Background

At present, 98% of oil wells in onshore oil fields are mechanical oil extraction, and sucker rod pump oil extraction is a main artificial lifting extraction mode of the oil fields. The artificial lifting technology has made great progress for more than ten years, but still does not fundamentally get rid of the series of problems of high energy consumption, large investment, eccentric wear of rod and pipe, large ground management difficulty and the like. In particular, in recent years, with the continuous progress of oil field exploration and development technology, deep oil reservoir burial, low-permeability and difficult-to-recover reserves are discovered and put into development and utilization. The well depth of the oil reservoir buried deep reaches more than 3000 meters, and as the number of horizontal wells, highly deviated wells and cluster wells is increased continuously, the problems of abrasion of rod pipes and the like are more severe, so that the well repairing operation is increased. The lifting efficiency of the conventional mechanical oil extraction artificial lifting equipment is low, and the energy consumption is high, so that the cost per ton of oil is increased.

The new technical requirements of the mechanical oil extraction production equipment with the sucker rod pump for the well depth and the medium-deep well above 3000 meters can be met: the device has the advantages of simple structure, reliability, durability, simple and convenient operation, easy maintenance, convenient parameter adjustment, low energy consumption, low material consumption, intelligent control, electronic patrol, remote monitoring, intelligent management, ultra-long stroke of more than 10 meters, low stroke frequency, large displacement and small dynamic load.

The problem that the existing equipment is lifted manually by the sucker-rod pump is that: the maximum stroke of the beam-pumping unit is 5.5 meters, when the pumping depth of the oil well reaches 3000 meters, the stroke loss of the oil well is close to 2 meters, and the effective stroke of the oil well pump is only 3.5 meters. The stroke length of the tower type walking beam-free oil pumping unit depends on the height of the tower, the maximum stroke is only 10 meters at present, and the effective stroke of an oil well pump with the pump hanging depth of 3000 meters is only 8 meters. The ultra-long stroke oil pumping unit which is popularized and applied in an oil field and mining field and has the stroke of 50 meters can reach to the CN201230127009.0 and 201420750926.8, and the problems that the occupied area of the oil pumping unit is not reduced, the oil pumping unit is basically the same as a beam pumping unit, and the weight of a single machine of the same type as the beam pumping unit is not obviously reduced are solved; secondly, the pumping unit model is limited by the breaking force of the flexible steel wire rope polished pumping rod to only achieve an eight-type pumping unit at present, the diameter of the flexible steel wire rope polished pumping rod is increased to 32mm from 30mm at present in the technical measure adopted in the field application at present, so that the diameter of a roller, the output torque of a speed reducer and the installed power are increased, and the production and manufacturing cost of the pumping unit is increased; thirdly, the maximum breaking force of the flexible steel wire rope polished pumping rod is only 200KN, so that the safety factor is low, the safe use coefficient of the 8-type pumping unit is 2.5, and the maximum breaking force of the 10-type pumping unit is only 2, so that the requirement of fixing the hoisting equipment to be 3.5 in the safety factor use rule of the hoisting steel wire rope is completely not met; and fourthly, the steel wire rope sucker rod realizes centering through a well head pulley and a well head packing, the steel wire rope sucker rod has the service life of one year under the dual actions of sliding friction and rolling friction of the well head pulley, and the average speed of 100 m multiplied by 78 yuan per meter of each well is 7800 yuan, so that the oil extraction production cost is increased, and the oil field development and production of deep wells, medium-deep wells and large well clusters are seriously restricted by the conventional manual oil extraction technology of the rod pump machinery at present.

The ultra-long stroke oil well pump related to patent No. 201410726196.2 adopts the working principle of the conventional tube pump, namely, the long pump barrel and the short plunger, when the length of the pump barrel reaches dozens of meters, and the plunger is only 1.2 meters, the fit clearance of the primary pump between the plunger and the pump barrel is only 0.03mm to 0.07mm, and the pump jamming fault of the oil well is very easy to occur in the stroke of 30m or 50 m.
