Abstract
The present invention relates to oil and gas extracting apparatus and method suitable for deep well, super deep well and high gas/liquid ratio oil well, and aims at saving power consumption and raising the hydrocarbon reservoir yield via utilizing the energy of stratum gas to lower the pressure in bottom of gas lift well and solve the artificial lift problem of various kinds of well. The technological scheme of the present invention includes: separating the stratum fluid in the well bottom with gas anchor into gas and liquid; making the separated gas to drive the pneumatic motors of booster pump; exhausting the exhaust gas to well head; and pumping the gas anchor separated liquid through pump barrel and oil pipe to exhaust in the well head. The present invention operates on the stratum gas to increase yield and save energy obviously.
Description
Technical field
The present invention relates to a kind of deep-well, ultradeep well, the oil recovery of high gas-liquid ratio oil gas well and device and method of liquid discharging gas producing of being specially adapted to, belong to oil and natural gas extraction field.
Background technology
In recover petroleum and natural gas process, when the stratum energy was sufficient, the oil gas well can adopt the blowing mode to produce; When the stratum energy reduces and moisture content rises when being not enough to keep blowing production, need makeup energy to transfer the artificial lift mode to and exploit.Artificial lift mode commonly used has: sucker rod pump, gaslift, electric submersible pump, hydraulic piston pump, hydraulic jet pump, gas jetpump, waterpower air driven pump, foam discharge opeing etc.Sucker rod pump is a present domestic and international application mechanical oil recovery method the most widely, but the application of the gas-water well in well, the especially gas field higher to gas liquid ratio is less, because sucker rod has limited sucker rod pump and has been used for deep-well and ultradeep well.Continuous gas lift is only applicable to the oil gas well condition that the stratum production capacity is higher and energy is sufficient, even have high gas-liquid ratio oil gas well, self having under the sufficient gas production situation still needs the gas injection makeup energy.Ground injecting gas boosting oil production that the inventor has proposed and liquid discharging gas producing device and method, it need utilize ground to inject gas drive mine gas booster pump, needs the people for energy is provided.
Summary of the invention
The objective of the invention is: be energy efficiency and raising oil-gas reservoir recovery ratio, make full use of the energy that flows to the gas of separating the gas-liquid mixture in shaft bottom from the stratum, the bottom pressure of gas-lift well is dropped to lower level, solve the artificial lift problem of high gas-liquid ratio oil gas well, low-voltage and low-yield energy oil gas well, deep-well and ultradeep well, special a kind of mine gas automatic boosting oil production and liquid discharging gas producing device and the method for proposing.
In order to achieve the above object, the present invention is by the following technical solutions: mine gas automatic boosting oil production and liquid discharging gas producing device and method, its device is made up of well head, sleeve pipe, oil pipe, packer, gas boosting pump, gas anchor, extraction pipe, it is characterized in that: sleeve pipe extends to the shaft bottom from well head, oil pipe is arranged in sleeve pipe, and tubing and casing links to each other with production tree at well head; Down-hole oil tube is provided with packer separates tubing and casing annular space and shaft bottom and oil pipe, and certain space is arranged at the packer bottom, is used for isolated gas under the storage well; In oil pipe upper packer position the gas boosting pump is installed, the downhole gas physical efficiency in the oil jacket annular space of packer bottom enters the power gas inlet of gas boosting pump motor; Gas anchor is positioned at gas boosting pump bottom, links to each other with pump end intake; The extraction pipe is positioned at well head, and an end is connected with the well head oil pipe, and the other end links to each other with the surface gathering and transferring pipe.
The course of work of the inventive method is: utilize the density contrast of liquids and gases, a plurality of air motors that adopt isolated stratum, down-hole gas to promote the gas boosting pump drive the pump piston motion, and liquid in the pump barrel is discharged well head, do not need from ground injecting gas energy conservation.The formation fluid that flows into the shaft bottom from the stratum separates by gas anchor in the down-hole, and isolated gas flows upward in the oil jacket annular space of packer bottom, and gas enters the mouth from booster pump power gas and enters an end of a plurality of air motors, promotes the motor piston motion; The other end of motor piston will lack gas and be discharged to oil pipe from the motor outlet opening, and weary gas is discharged well head extraction pipe by oil pipe; The motor piston motion drives the pump piston motion, the inlet valve of pump suction side is opened, enter the pump barrel suction side from the isolated liquid of gas anchor, the blow off valve of outlet side of pump is opened simultaneously, the pump piston motion is pressed into the oil jacket annular space with outlet side of pump well liquid from pump discharge, and well liquid is discharged to well head extraction pipe from the oil jacket annular space; When motor piston moved to the terminal point of motor one end, mine gas entered the other end of motor piston, motor piston motion commutation, and circulation is so repeatedly recovered the oil and liquid discharging gas producing thereby finish.Oil pipe also can be made discharging tube, and at this moment the oil jacket annular space is made stack.
Compared with prior art, the present invention has following beneficial effect: (1) relies on stratum gas work, the energy Increasing Production and Energy Saving, and effect is remarkable, has improved system effectiveness significantly; (2) have the advantage of sucker rod pump, bottom pressure can be dropped to the level lower, can the oil well condition have stronger applicability low-voltage and low-yield than gaslift; (3) do not need sucker rod and special down-hole and ground link, be applicable to the artificial lift technology of deep-well and ultradeep well.
