The oil extraction device has simple process flow, reduces a large amount of ground and underground equipment compared with the common mechanical oil extraction mode, greatly reduces the production cost, increases the sectional area of an oil flow channel for extraction because no oil pipe is arranged in a shaft, is beneficial to improving the thick oil extraction effect and increasing the oil well yield.
Description
The utility model relates to a kind of particularly two-tube hydraulic power extracting device of oil of heavy oil wells exploitation of oil well production that is used for.
At present, both at home and abroad the mechanical oil recovery equip ment of Oilfield using mainly contain the sucker rod pumping device that constitutes by ground oil pumper and down-hole sucker rod, oil well pump, the electric submersible pumping device formed by GCU, stube cable and downhole electrical motor, protector, electric centrifugal pump, the three major types such as hydraulic piston pump oil extracting device formed by ground power fluid feed system and down-hole Piston Reciprocating Pump.The major defect of above-mentioned all kinds of extracting device of oil is complex manufacturing, need to be equipped with, adopt large number of ground and underground equipment, and the down-hole all need be provided with tubing string, thereby oil well capital construction and equipment investment height.In addition, power consumption is higher when the oil well ordinary production, need carry out underground work when oil well breaks down, and cost of winning is increased, and the oil well production management workload is increased.
The purpose of this utility model is to provide that a kind of production technology is simple, ground, underground equipment are few, oil well capital investment and the low two-tube hydraulic power extracting device of oil of cost of production.
The utility model is to realize like this.This kind extracting device of oil is made up of ground hydraulic pump, special-purpose well head, feed tube, liquid back pipe, packer, oil pipe, hydraulic oil producing pump, adopt the power source of ground hydraulic pump as whole oil extraction system work, by the two-tube hydraulic circuit in one-in-and-one-out down-hole that links to each other with hydraulic pump, drive the underwell hydraulic oil producing pump with crude oil extraction from well.The structure of this device, assembling feature are as follows: feed tube that is connected with ground hydraulic pump import and export pipeline and liquid back pipe pass through special-purpose well head G.I.H arranged side by side respectively, feed tube, liquid back pipe lower end are connected with the import and export of hydraulic oil producing pump both sides respectively, hydraulic oil producing pump top is connected with one section oil pipe by reducer union, the oil pipe upper end links to each other with packer with union formula special fit, and this packer is connected with feed tube, the liquid back pipe of oil pipe both sides simultaneously.Before the use, with the diplopore elevator lower end is connected with the advancing of hydraulic oil producing pump, returns the two-tube and oil pipe of liquid G.I.H abreast, make the oil extraction pump depth of setting be positioned at the perforated interval middle and lower part, the packer that is attached thereto is positioned at the oil reservoir top; After special-purpose well head is installed two-tube upper end is connected with hydraulic pump import and export pipeline respectively, can puts into production.During use, elder generation's primer fluid press pump, power fluid flow to the hydraulic oil producing pump and drives its work through feed tube with certain flow velocity and operating pressure, and before this, the cross through hole of the power fluid of the packer of flowing through on it enters the expansion tire to be made it distending and be adjacent to the seal pack effect of playing with sleeve pipe; The hydraulic oil producing pump gives rise to the packer top with the crude oil in oil reservoir and the packer below pit shaft through oil pipe, and under the situation of continuous operation, the crude oil liquid level constantly rises in the well, and from the wellhead flowline extraction.Meanwhile, the power fluid that flows out from the outlet of hydraulic oil producing pump opposite side then returns the ground hydraulic system that flow to along liquid back pipe, repeats said process, forms continuous closed cycle working method.Under this kind working method, crude oil is continuously by extraction.This kind extracting device of oil adopts the lower conduction oil of viscosity as power fluid.For heavy oil wells, ground need be set up heating system power fluid is heated, and the heat power liquid by circulation in the down-hole is two-tube makes it reduce viscosity the viscous crude in heat transferred oil reservoir and the pit shaft, improves liquidity, in order to extraction.
The utility model modern design, technological process is simple, reduces large number of ground and underground equipment than common mechanical oil production model, particularly ground cancellation oil pumper, down-hole cancellation R a T post, thereby can save great deal of steel and power consumption, cost of production is reduced greatly.Adopt this kind extracting device of oil owing to do not establish oil pipe in the pit shaft, extraction oil flow channel sectional area is increased, flow resistance reduces, and more can play the viscosity reduction effect in that the situation of utilizing heat power liquid is next, helps improving the thickened oil recovery effect, improves crude output.
