Description

Central fluid supply station many wells cluster U-shaped pipe extracting device of oil

Technical field

The utility model is a kind of central fluid supply station many wells cluster U-shaped pipe extracting device of oil, belongs to mechanical oil recovery technology frontier.

Background technology

In oil field development, along with the prolongation of Development life, oil well all will proceed to mechanical oil production model.According to incompletely statistics, in the current 2,000,000 mouthfuls of oil wells in the whole world, mechanical oil recovery accounts for more than 95%.

Mechanical oil production model conventional is both at home and abroad mainly electric submersible pumping, screw pump oil production, jet injector oil production, double leval jib beam pumping unit sucker rod pumping and the Balance electric-machine directly-driven vertical oil pumping extraction oil in order to energy efficiency improvement.Although above-mentioned oil production method respectively has superiority, technology is also respectively had to limit to.

Electric submersible pumping adapts to huge discharge discharge opeing needs, but wants lifting fluid column weight and overcome frictional resistance, and energy consumption is high, and application life is short, and replacement cost and the high cost that enters well cable govern the large-scale promotion of this kind of oil production method.

Screw pump oil production needs lifting fluid column weight equally and overcomes frictional resistance, and is difficult to adapt to deep-well, inclined shaft, thin oil well, and the scope of application is less.

Jet injector oil production does not have moving component, liquid lifting is realized by the momentum between jet power and formation fluid conversion, do not limit by lift height, technique is simple, with low cost, operating principle be can yet be regarded as a kind of comparatively ideal oil production method, but the wearing and tearing of high pressure nozzle and the inadaptable of low production capacity well constrain its long-life spread.

The vertical oil-pumping machine of double leval jib beam pumping unit and improvement in theory a lifting liquid weight half load, and tired reality is reliable, durable in use, still accounts for about 90% of mechanical oil recovery so far, becomes the leading type of mechanical oil recovery.But huge structure, maintenance heaviness, somewhat expensive and side-abrasion of rod string cause down-hole fault rate high, use limited, be more and more not suitable with the development need of modern society's low-carbon economy to inclined shaft, ultradeep well.

Last century the eighties, hydraulic piston pump was once introduced in Some Domestic oil field, caused extensive concern, but gave prominence to due to the fault of construction of controlling organization and reversal valve, and the construction cost of Surface power drive liquid system is higher, just exits site of deployment very soon.

Along with the in-depth of oil field development, many contradictions seriously governs oil field development:

One is get more and more along with deviated directional drilling with from formula well, and the side-abrasion of rod string that hole deviation problem causes becomes the difficult problem that sucker rod pump is difficult to capture;

Two is restrict by the more and more serious sand of oil field middle and later periods exploitation, wax, thick, gas, and above-mentioned oil production method has been difficult to adapt to;

Three be along with deeply taking out, the increasing of huge discharge well, close to and exceed the load limit of above-mentioned mechanical oil production model;

Four be energy-conservation, safety, environmental protection, substantially non-maintaining Modern Enterprise Administration require the Innovation and development of urgently new oil-extract technique, new technology.

How to capture the technical bottleneck of above-mentioned many oil production technology, over nearly 10 years, the domestic research around hydraulic defueling pump continues deeply, successively disclose 60 multinomial RELATED APPLICATIONS, but all do not drop into on-the-spot application, tracing it to its cause, the poor reliability of its hydraulic change(-)over, flow passage resistance force of waterproof be large, being difficult to the limitation of the technology such as reply corrosion and scaling, wax deposition, viscous crude is the crux being difficult to filed application.

Follow the tracks of domestic and international mechanical oil recovery 40 years, through preferred to the contrast of all kinds of mechanical oil production model, U-shaped pipe recovers the oil and only need overcome double rubs power between liquid and tube wall, and its lifting force to be less than etc. 30% of head of liquid, and therefore U-shaped pipe oil recovery principle is the optimal selection of all oil production methods.

How to make that U-shaped pipe oil recovery technique is integrated, scale, both extensively adapted to single well production, and adapted to again cluster well, block and whole oil field, thus start the directionality milestone of cost efficiency, and became the important topic of Continuous Innovation.
