Description
Technical field:
The utility model belongs to the oil extraction in oil field mechanical field, particularly relates to a kind of offshore production platform cluster well oil extractor.
Background technology:
Sucker rod pumping is the maximum a kind of oil production method of land use.Capital equipment comprises oil pumper, sucker rod and oil well pump.Its operating principle is: Surface power drive equipment gives rise to downhole crude on the ground by the deep well pump work of sucker rod drive down-hole.At present most widely used is beam pumping unit---the deep well pump oil pumping.This apparatus structure is simple, reliable operation, convenient management, compliance are stronger, be suitable for shallow well and low yield oil field, so it occupies critical role in mechanical oil recovery.But its shortcoming is also arranged, as the ground installation volume and weight is large, pumpage is little, can not adapt to well complex situations and the offshore platform oil recoveries such as sand, wax, water, viscous crude.
In the oilfield development process, because stratum energy descends gradually, oil well can not keep blowing, or flowing production rate crosses when low, just must carry out mechanical oil recovery.Offshore oil production artificial lift equipment is most popular both at home and abroad is electric submersible pump, screw pump, water conservancy piston pump, water conservancy jet pump etc., these several artificial lift modes not only are subject to reservoir condition, oil well condition, ground (platform) conditionality, but also will be subject to the restriction of benefit and management expectancy; Ask the aspects such as economy, technological adaptability can both relatively conform with concrete field situation at the selection upper stress of oil production method, thereby can effectively bring into play the oil field jacking capacity, give full play to the oil productive capacity of oil reservoir.The basic principle of selecting is: adapt to the requirement of the various hole conditions of offshore platform cluster well group, be based on underground, take the characteristics of oil reservoir and liquid-producing capacity as the basis, analyze the productivity characteristic of oil reservoir different development phases and different lift method to the lifting effect of oil well production system.The characteristics of electric submersible pump are: discharge capacity is large, lift is high, flow equalization, tubing life long, ground installation is simple, be easy to realize automatically control and have and take preferably sand, take the advantage such as wax ability, but one-time investment is high, construction, the management expectancy technical condition are strict, be subjected to the restriction of the heat-resisting degree of motor, applicable well depth generally is no more than 3000 meters; Can affect pump efficiency when oil well output change and exploitation heavy oil, also not allow more gas (generally being no more than 2% volume content) to enter in the pump.Dried turning easily occurs in electric submersible pump when oil well liquid-supplying is not enough, cause rapid wearing to lose efficacy, and device structure is complicated, workmanship is had relatively high expectations, and according to its characteristics, it is applicable to well, the inclined shaft that high-yield well, well depth do not surpass 3000 meters.
Screw pump belongs to pusher displacement pump, critical piece is rotor and stator, rotor is a large tooth depth of large helical pitch and than the screw rod (rotor) of warp in the minor spiral, stator is the rubber swivel nut that the double end helical is arranged that matches with it, between rotor and stator, formed like this space of storage medium, when rotor turned round in stator, medium was moved to discharging by the suction side vertically.Screw pump has following advantage:
1, pressure and range of flow are broad;
2, transport kind and the range of viscosities broadness of liquid;
3, because the pivoting part inertia force in the pump is lower, so can use very high rotating speed;
4, intake performance is good, has suction capacity;
5, flow is evenly continuous, vibrates littlely, and noise is low;
6, compare with other drum pump, not too responsive to the gas and the dirt that enter.
The shortcoming of screw pump is: processing and the matching requirements of screw rod are higher, and the stator swivel nut is fragile.The screw pump sucker rods post is stressed more complicated in the down-hole, bears again shear stress when bearing tensile stress.Whether the rod string that adopts at present can satisfy the normal need of production of screw pump, and namely whether combined strength bination can reach requirement, and perhaps intensity is too high causes waste, and perhaps intensity is excessively low causes roofbolt to lose efficacy and cause work accident.The screw pump depth of falling well generally is no more than 2000 meters.The service life of screw pump is short generally at 6～8 months, and the inspection pump often.
Along with the raising of exploration level, China explores at the deep-sea and attaches most importance to, the deep-sea oil gas aboundresources, and the average reserves of oil gas field are obviously greater than the shallow sea.At present the offshore field degree of depth reaches 4000 meters～6000 meters well and constantly occurs.Therefore, marine deep mining requires higher to the compliance of mechanical oil recovery equipment, because most widely used electric submersible pump, screw pump etc. have limitation in the present marine mechanical oil recovery, the darkest oil well that can only exploit 3000 meters, compliance is not high, comprehensive benefit is low, and significant discomfort is answered the exploitation of marine super dark oil well.
