Abstract
This is a gas lifting method by use of the gas generated by diesel motor. After treatment of the gas generated by diesel motor, the main components are nitrogen and carbon dioxide. The gas could be used for gas lifting or pipe cleaning in gas well. Also because of good solubility and viscosity reduction ability of the gas, It can be used for gas lifting for heavy oil well. After filtering, quench and compressed, the gas exhausted from the diesel motor is compressed into the well cycle.
Description
The present invention relates to produce safe gas in a kind of oil exploration and the exploitation and be used for the method that the oil gas gas well gas is lifted.
Technical background: 1, oil well generally adopts the modes of production such as pumping production, electric pump, hydraulic jet pump at present, adopt these modes cost of production height that recovers the oil for outlying well, scattered well, stripper well, inclined shaft, directional well, if adopt gas-lift production mode cost relatively the end of than, when if local natural gas or nitrogen are sufficient, gas-lift production use natural gas or nitrogen are the safest.When source of the gas is not enough,, strengthen gaslift cost and poor stability if adopt gaslift then must use chemical anti-knock agent.2, for ponding in the gas well manufacturing process and measure working fluid, before the gas well ordinary production, all must get rid of pit shaft liquid, modes such as electric pump, oil pumper band pump, gaslift are mainly used in gas well discharge opeing at present.Wherein good with gaslift mode discharge opeing cost minimum frequency especially.But also there is limitation in gaslift, is difficult to obtain large-area use.As everyone knows, when natural gas mixes with air, when reaching 5.3-14%, airborne natural gas content just might blast, in order to prevent gas explosion, the limitation that it uses shows following: present gaslift fluid-discharge technology must adopt the local natural gas of producing or use nitrogen, if local natural air-air source deficiency then uses the nitrogen cost higher relatively, and the preparation suffering.If use cheap air, because gaslift is under high pressure to work, safety is relatively poor.Relevant document forbids to use the air gaslift.
The purpose of this invention is to provide in a kind of oil exploration and the exploitation and can produce the method that safe gas is used for the act of oil gas gas well gas.
The present invention adopts following principle to realize: gaslift has simple to operate, with low cost for hyposmosis, the exploitation in low pressure oil field, outlying well, stripper well, electric power installation difficulty or the oil well of uneconomic individual well (block), deep-well, knot La Jing, inclined shaft and seriously corroded that difficulty is big, residual sour discharge opeing and the gas well discharge opeing behind the oil well acidation.Use the air gaslift to exist potential safety hazard to cause gaslift must use natural gas or nitrogen, so just limited the range of application of gaslift technology.This invention mainly is to solve gaslift process source of the gas and safety problem.Limitation at gaslift technology, in order to solve the gaslift source of the gas and to use the explosive shortcoming of air, the invention provides a kind of method: utilize flue gas that diesel combustion produces after treatment, this gas main component is nitrogen and carbon dioxide, natural gas mixes afterwards ratio no matter in how many scopes in this gas and the well, can not produce the danger of blast, therefore can carry out gas-lift production at high oil-gas ratio well, condensation oil well etc.; Carry out the gaslift discharge opeing at gas well, this gas also can be used as the pipeline purging of gas well pipeline.Because nitrogen and carbon dioxide have dissolving and viscosity reduction effect preferably, also can carry out gas-lift production simultaneously for part common heavy oil well.
Beneficial effect: the safe gas that this method produces cooperates gaslift technology to have application widely.Its cost for oil production and gas well discharge opeing cost are significantly less than the running cost of alternate manner.
Below be implementation method of the present invention: utilize flue gas that diesel combustion produces after treatment, this gas main component is nitrogen and carbon dioxide, natural gas mixes afterwards ratio no matter in how many scopes in this gas and the well, can not produce the danger of blast, therefore can carry out gas-lift production at high oil-gas ratio well, condensation oil well etc.; Carry out the gaslift discharge opeing at gas well, this gas also can be used as the pipeline purging of gas well pipeline.Because nitrogen and carbon dioxide have dissolving and viscosity reduction effect preferably, also can carry out gas-lift production simultaneously for part common heavy oil well.The oil gas well is when gaslift, after the flue gas process filtration that diesel combustion produces, cooling, the pressurized treatment, enter compressor compresses, enter the oil well annular space then, because the flue gas main component that burning produces is carbon dioxide and nitrogen gas, its with can not produce blast after natural gas in the oil well mixes.The gaslift of carrying out that just can be safe is constructed.
Claims (1)
1, a kind of safe gas that produces is used for the method that the oil gas gas well gas is lifted, and it is characterized in that: after the flue gas process filtration that diesel combustion produces, cooling, the pressurized treatment, enter compressor compresses, enter the oil well annular space then.
