Abstract
A gas displacing method for recovering petroleum features that the gas displacing jet pump is installed between oil-bearing stratum and ground surface and a compresor is used for filling the natural gas in said gas displacing jet pump which plays the role of the cosprayer of recovered material. Said gas displacing jet pump is composed of gas mixing tube, oil pipe and sleeve pipe, which are sleeved together. Its advantages are high utilization rate of natural gas, no damage to oil or gas bearing stratum, and high recovery rate.
Description
Technical field:
The present invention relates to a kind of oil field oil production method, particularly about a kind of gas drive oil production method.
Background technology:
In the oil field development at present, later stage displacement of reservoir oil power is water and chemical agent water, full oil field gross area water filling, water has serious corrosion traction to the DDGS of oil reservoir, easily produces a large amount of sulfide corrosion sleeve pipes, destroys oil reservoir calcium, the skeleton of things such as magnesium causes silt and moves, stop up oil reservoir, be de-plugging, carry out a large amount of large tracts of land fracture acidizings, sidetracking, interlayer is ganged up, interfere with each other a large amount of water fillings, big again volume production water, a large amount of water treatments, need a large amount of down-holes, Ground Operation causes the complex manufacturing variation, and cost of production improves greatly, the exploitation cycle stretch-out, ultimate recovery descends.
Summary of the invention:
The purpose of this invention is to provide a kind of gas drive oil production method, it can make the utilization rate of natural gas improve greatly, and oil-gas Layer is not had destruction, and recovery ratio improves, and cost of production is low.
The technical solution used in the present invention is: design a kind of gas drive oil production method, it is characterized in that: between the ground gas-drive jet pump is installed at oil reservoir, with compressor natural gas is injected in the gas-drive jet pump by deflector, play output object helped the spray apparatus effect.
Described gas-drive jet pump is to be made of gas mixing pipe, oil pipe, casing pipe sleeve together, is with gas mixing pipe in the oil pipe, oil pipe is with sleeve pipe outward, on the oil pipe bottom interior surface seal receptacle is arranged, and on the tracheae bottom outer surface end socket is arranged, trunnion is arranged in the tracheae, and there is nozzle the trunnion below; Gas-drive jet pump, top are mounting flanges.
Described deflector is to be communicated with pipeline on the packing seat, is communicated with control valve and three way cock on the pipeline; Also be connected with indicating meter on the pipeline.
Described oil pipe is 2 ', 2 '/2 " pipelines.
Characteristics of the present invention are: because the present invention passes through jet pump with gas as motive fluid, produce vacuum or low-pressure area, make well liquid flow to low-pressure area, nozzle is converted to swiftly flowing gas kinetic energy with the pressure energy of the high voltage power gas of flowing through, and behind mouth, form region of no pressure or low-pressure area between trunnion, the product of swiftly flowing low-pressure gas and the oil reservoir of the low-pressure area that is inhaled into is pushed to ground and reaches the oil recovery purpose after forming mixed gas thing between trunnion.Adopt gas jet pump to recover the oil in full field produces overall process, inject natural gas in the oil field oil-gas Layer is not had destruction, natural gas can be taken ponding out of under the effect of jet pump, increase output.Adopting this technology also can be that the oil field oil extraction pump is done the basis from limit portion or low-lying water filling, and compressor is installed on the ground, and easy operating is used to realize the adjusting of output.This oil production technology not only improves output, and total exploitation drops into also and descends greatly.And jet pump is directly to change by the fluid energy between fluid pressure energy and the kinetic energy to realize transmitting energy.Jet pump does not have moving component, flows to vertically upward, and is parallel with the well self-energy, forms and makes a concerted effort, well liquid is elected in suction, and the discharge capacity scope is big, compact conformation, and it can be applicable to lack of water ground, plateau directional well, horizontal well, inclined shaft, marine from the formula well, high and cold district well, high gassiness, content of wax well.Natural gas is light, is easy to flow, and easily occupies oil reservoir and occupies high spatial and drive house beam oil, and high in addition dissolubility is cleaned high-viscosity oil in the oil reservoir.Natural gas does not have water-soluble, does not destroy the ultimate recovery that the oil reservoir skeleton can improve the oil field, and natural gas is that compressible easy dilatant makes the oil gas excitement, pushes away away silt in oil reservoir and the pit shaft, removes oil layer blocking and improves oil production.This technology is to there being a large amount of natural gases, and the oil field that is about to stop-spraying can be carried out the people and exploited for helping spray, until the oil field is withered have a rest till.The oil gas field high to natural gas content, recover the oil on one side, pour into natural gas on one side and store in case of need.Natural gas does not have destruction to reservoir physical property can not change reservoir physical property, and oil reservoir reason skeleton is effectively preserved, and carries out the water filling of limit portion, and crestal gas injection middle part oil recovery benefit is better.
The invention will be further described below in conjunction with the embodiment accompanying drawing.
