Description

U-shaped pipe individual well fluid power self-loopa extracting device of oil

Technical field

This use is novel is a kind of U-shaped pipe individual well fluid power self-loopa extracting device of oil, belongs to mechanical oil recovery frontier.

Background technology

In oil field development, except early field life relies on the oil flow production of stratum energy, along with the prolongation of Development life, oil well all will proceed to mechanical lift oil production method.According to incompletely statistics, the whole world has approximately 2,000,000 mouthfuls of oil wells at present, and wherein mechanical oil recovery accounts for more than 95%.

Both at home and abroad conventional mechanical oil production model is mainly electric submersible pumping, screw pump oil production, jet injector oil production, four connecting-rod beam formula oil pumper sucker rod pumpings and for the improved Balance electric-machine directly-driven of energy efficiency vertical oil pumping extraction oil.Although above-mentioned oil production method respectively has superiority, also respectively there is technology limitation.

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

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

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

The load partly of a four connecting-rod beam formula oil pumpers and improved vertical oil-pumping machine lifting liquid weight after balance, and tired reality is reliable, durable in use, still accounts for so far 90% left and right of mechanical oil recovery, becomes the leading type of mechanical oil recovery.But huge structure, safeguard that heavy, somewhat expensive and side-abrasion of rod string cause down-hole fault rate high, inclined shaft, ultradeep well, heavy oil wells are used limited, be more and more not suitable with the development need of modern society's low-carbon economy.

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

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

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

The 2nd, restricted by the more and more serious sand of oil field middle and later periods exploitation, wax, thick, gas, above-mentioned oil production method has been difficult to adapt to;

The 3rd, along with deeply taking out, the increasing of large discharge capacity well, approach and exceed the load limit of above-mentioned mechanical oil production model;

The 4th, energy-conservation, safety, environmental protection, substantially non-maintaining Modern Enterprise Administration require urgently to recover the oil innovation and the development of new technology, new technology.

How to capture the limitation of the technology bottleneck of above-mentioned many oil production technology, over nearly 10 years, the domestic research around hydraulic defueling pump continues deeply, 60 multinomial relevant patents are successively disclosed, for technological innovation provides valuable enlightenment, but all do not drop into on-the-spot application, trace it to its cause, the commutation up and down that its hydraulic change(-)over complexity causes replaces the closure of moment fluid course and opens poor reliability, flow passage resistance force of waterproof is large, the assembly difficulty of the multiple sealing surfaces of inner/outer tube and reply sand, wax, thick, the limitation of the technology such as gas are the cruxs that is difficult to mining site application, only have it is further improved and is optimized, could realize better the conversion to productivity.

For the many contradictions of above-mentioned restriction mechanical oil recovery, advantage and defect that the present invention contrasts above-mentioned all kinds of oil production methods by analysis draw the following conclusions:

Above-mentioned many oil production methods, need lifting liquid weight and frictional resistance sum mostly, cause high energy consumption and high material-consumption.

According to U-shaped pipe principle: when same liquid is housed in U-shaped pipe, liquid always flows to the other end from one end, flow to always two ends liquid level equally flat till.Therefore, lifting U-shaped liquid in pipe, only need overcome and between liquid and tube wall, come and go frictional force, and its lifting force such as is less than at 30% of the head of liquid.Thereby for adapting to better the demand of modern oil production technology, through optimizing screening, U-shaped pipe oil recovery principle is the optimal selection of all oil production methods.
