EXAMPLE: A C-456D-256-120 Unit with 4 No. 2RO Counterweights and 4 No. 2S Auxiliary Weights would have a maximum counterbalance effect of 16,975 pounds in the 120" stroke. This effect includes a structural unbalance of +55 poun ds. If the counterbalance effect is desired for the 85" stroke, subtract the structural unbalance from the e ffect in the 120" stroke and multiply this difference by the ratio of 120 ÷ 85, then add the structural unbalance to this product. Thus, counterbalance effect in the 85" stroke = [16,975 – (+55)] x 120/85 + (+55) = 16,920 x 120/85 +55 = 23,942 pounds. Structural unbalance with a negative ( – ) sign indicates a walking beam assembly that is heavy on the well end. Structural unbalance without the negative sign indicates a walking beam assembly that is heavy on the gear reducer end.

* Use only one aux. weight per counterweight on belt cover side on 40D units. NOTE: To convert effective counterbalance to maximum counterbalance torque for dynamometer card analysis, multiply the pounds counterbalance, minus the structural unbalance, by the torque factor at the 90°crank position.

MARK II UNITORQUE PUMPING UNITS

The M ark II P um ping U nit, due to its un ique geom etry and phased counterbalance feature, low ers peak torque and ho rsep ow er req uirem ents. The unusual geom etry of the M ark II prod uces a som ew hat slow er up stroke and faster do w n stroke w ith red uced acceleration w here the load is g reatest, resulting in low er peak loads and longer rod life.




Mar k II Geometr y Reduces Rod Load and Peak Tor que

T

Th e M ark II's unique U N ITO R Q U E geom etry is characterized by three (3) basic configurations w hich red uce the rod load and peak torque over that of a conventionalpum ping unit. The design characteristics w hich m ake the M ark II unique are: •S hifting the gearb ox from direc tly under the eq ualizer tow ards the S am son p ost turning in a preferred direction of rotation, creates an upstroke that occurs in ap proxim ately 195° of crank rotation and a d ow nstroke o f ap proxim ately 16 5° of crank rotation. •P lacing the eq ualizer betw een the ho rsehead and the S am son post creates a “ push-up”or “ C lass 3” lever system . The 19 5° up stroke, coup led w ith the front m ounted geo m etry, reduces the acc eleration at the beg inning of the u pstroke w here the load is greatest, thereby effecting a reduction in polished rod load . Locating the cross-yoke forw ard of the gear red ucer creates a g reater m echanicalad vantag e for lifting the heavy load on the upstroke, and a lesser m echanicalad vantag e for the red uced dow nstroke load (i.e., the m axim um upstroke torque factor is red uced w hile the m axim um dow nstroke torque factor is increased). •A n angular offset in the cran k that produces a m ore effective co unterbalance torque w hich at the beginning of the upstroke “ lags”the w ellload 1 torque ap proxim ately 7 ⁄2°. S im ilarly, at the beginning of the d ow nstroke, this sam e o ffset co ndition produces a counter balance torque w hich “ leads” 1 the w ellload torque approxim ately 7 ⁄2°. Ind ep en dently these features w ould no t produce a relatively uniform torque, but w orking together a “ unitorque”system is o btained w hich can red uce the torque on the gearbox u p to 35 % as w ellas low ering pow er co sts and often, prim e m over size.

Uniform torque can be obtained under ideal conditions. NOTE: The Mark II Unit must be operated in a counter-clockwise direction (standing at the side of the unit with the wellhead to the r ight).

“Two-Point” Suspension bases are standard for all Lufkin Mark II Pumping Units. The two-point base permits the use of small salvageable precast concrete blocks or fabricated foundation pads under the front and rear of the unit. Precast concrete blocks reduce concrete requirements by approximately 80%. This simple base suspension/foundation design significantly reduces installation time.

AIR BALANCED PUMPING UNITS

The u tilization of co m pressed air instead of heavy cast iron counterw eights allow s m ore accurate fingertip controlof counterbalance. A s a result, the w eight of the unit is g reatly reduced, significantly low ering transp ortation and installation costs. A ir B alanced units have a d istinct advantage in the larger sizes w ith long strokes, w here sp ace an d w eight restrictions prohibit the u se of co nventional cran k b alanced units.




Air Balanced Pumping Units pr ovide: •P erfect counterbalance w ith finger-tip control. •Low er installation cost. •C om pact and portab le; idealfor w elltesting. •S m allsize and lighter w eight m ake unit ideal for exp ort. •S troke lengths to 20 feet for high volum e p roduction from great dep ths. These are som e of the ou tstanding ad vantages of Lufkin A ir B alanced P um ping U nits. These units em ploy com pressed air to counterbalance the w ell load rather than b eam w eights or crank w eights. The air system has been so sim plified that the o nly co ntinuously operating parts are the b alance cylinder and piston. The reservoir capacity o f the cylinder is en larged by a steelreceiver w hich m oves w ith the cylinder as a unit. O n engine-driven un its, w hen the system is in need of air, an autom atic reg ulator engag es an air operated clutch (driven by one b elt from the u nit sheave) and rep laces any lost air. The operator sets the reg ulator, initially, at a pressure sufficient to counterbalance the w ellload. Then, this p ressure is m aintained autom atically. S hould the load ch ange ap preciably, a slight adjustm ent of the regulator w illrestore perfect co un terbalance. A safety shut-off sw itch is available, w hich w ill ground out the en gine, or shut off the m otor, if pressure should exceed a p reset figure or fallbelow a m inim um pre-set figure. For units p um ping w ith electricity, a separate m otordriven com pressor assem bly is standard equipm ent. Lufkin A ir B alanced U nits are ap proxim ately 35% shorter and 40% lighter than crank-type units, w hich m akes them idealfor use as p ortab le o r test units, and for installation on piling or su perstructures. S ince changing co unterbalance effect is a m atter of adjusting a valve, air balanced units are idealfor use in testing w ells. A llof the rugged ness and sim plicity of co nventional Lufkin P um ping U nits are inco rporated in the design of Lufkin's A ir B alanced P um ping U nits.

SLANT HOLE PUMPING UNITS


Slant Hole Pumping Units These units are one of the latest exa m ples of Lufkin's cap ability to design an d m anufac ture rod pum ping units that m eet new or un usual w ellsp ecifications. D evelopm ents in extended -reach, horizontaland deviated drilling technologies have proven successfulin helping operators tap into previously hard to reach reserves. In order to efficiently p roduce oilfrom these unco nventionaldeviated w ell bores, a new generation of production equipm ent has been req uired . A s it has so often in response to other sp ecialindustry needs, Lufkin delivered an effective rod pum ping solution . . . the Lufkin S lant H ole pum ping unit. Each ofthese units can be custom -built to m eet individualw ellsp ecifications.

The Slant Hole Unit is an example of Lufkin's ability to design and manufacture pumping units for special applications.

GEAR REDUCER AND LUBRICATION DATA

Lufkin designed and manufactured herringbone gears (double helical) have p roven to be the standard of excellen ce for pum ping unit gear red ucers. H erringbone gears are less sensitive to m isalignm ent and resist torque reversals better than o ther types of gears. H eavy-duty sleeve bushings o n the cranksh aft and straight roller bearings o n the high speed and interm ed iate shafts need no ad justm ent at assem bly or w hen field service is req uired . The no dular iron gears w ith high strength alloy pinion used by m ost m anufacturers of pum ping units w ere p ioneered by Lufkin over thirty-tw o years ago. The rug ged tw o-piece h ousing is m anufactured sp ecifically for oilfield pum ping ap plications. Churchill’s precision-cut helical gears are encased in a strong, heavy-w alled , cast-iron gear red ucer ho using . Fo r sm aller, beam balanced pum ping un its, these g ear red ucers are the m ost econom icaland reliab le availab le. Inco rporated into the h igh sp eed end of the g ear reducer is C hurch ill’ s unique S tepD ow n design, w hich m inim izes shaft deflection and im proves proper gear m eshing. P ositive lubrication of the h eat treated, nodular gears and steelalloy pinions is en sured by a w iper-type system . A built-in sight gau ge allow s im m ediate visual insp ection o f the oillevelin the gear reducer housing. A lltapered roller bearing cups are m ounted in bearing carriers, a unique configuration w hich m inim izes field rep lacem en t tim e and also prevents dam ag e to the housing should a bearing fail.

As long as the oil is maintained at the proper level, the slow speed and high speed gears dip in oil and provide continuous lubrication to the gear mesh. Large oil wipers direct a flood of oil into oversized oil troughs which in turn provide each individual bearing with more than adequate lubrication above five SPM. Add high speed wipers below five SPM.

AUTOMATION

leading rod pump design and analysis software programs. Lufkin Automation’s new release of these

Plus, the MPC controller has a built-in, quantitative dynamometer system that continuously monitors and analyzes pumping dynamics. A unique operator interface with a user-friendly keypad graphically displays detailed, real-time well information. Dynagraph cards store valuable information such as percent run time history, counterbalance and time on/time off plots for later retrieval and comparison. And, the controller is easily integrated with most third-party SCADA software packages.

The OPTIMIZER Economy Rod Pump Controller offers producers a third, simpler control option. This very affordable, low-maintenance product cost-effec-

tively maximizes the efficiency of marginal wells by turning the pumping unit on only when the pump is filling. Power requirements and the adverse effects of “fluid pound” are significantly minimized.

programs cover both deviated and vertical wells in one software package, and new features have been included to improve the programs’ user interface. SROD is the design and predictive program, and DIAG is the analysis program. Since most wells do not have perfectly vertical wellbores, both programs have been designed to handle deviated wellbores. A deviated well can increase the chances of rod-tubing drag and downhole friction, which in turn can cause severe equipment wear, overloading, out-of-balance problems, power loss and rod buckling. SROD and DIAG have the superior mathematical models to correctly identify and solve these problems. Combining the design and predictive power of SROD with the accurate diagnostic capabilities of DIAG provides the operator with the ultimate solution for designing new installations and optimizing existing wells. Program features include: SROD

The Optimizer controller is capable of recording and displaying runtime over the last 72-hour run period, providing operators with the means to detect changes in mechanical or reservoir conditions. Because the product requires no traditional position transducers or load cells, it virtually eliminates maintenance problems.
