The complex column jacket for oil production and water production comprises an outer oil pipe and an inner oil pipe which are put down into a sleeve of an oil well; the lower end of the inner oil pipe is provided with the one way valve, and the upper end of the inner oil pipe is provided with an oil outlet; the lower end of the outer oil pipe is provided with the one way valve, and the upper end of the outer oil pipe is connected with the gas injection device; the gas injection device includes a solenoid switch connected with the outer oil pipe, an electromagnetic pressure relief valve, a compressor, an accumulator and a gas accumulator tank which is connected with the compressor and the electromagnetic pressure relief valve. The utility model is applied to the gas production and oil production techniques in the oil field.
Description
One, technical field
The utility model relates to the method and apparatus of producing oil, gas, water from well, particularly a kind of multiple tubular pile type bar-free gas-production oil-production device.
Two, background technology
Traditional gas-production oil-production equipment is mainly traditional down-hole string and deep well pump, electric submersible pump, screw pump, these oil extraction pumps all are that the exploitation of oil gas water is made or made and contributing, but they also exist separately shortcoming or deficiency simultaneously: 1. cavitation easily takes place in deep well pump in gas well, and the eccentric wear between the pipe bar, efficient is low, energy loss is big, if side-abrasion of rod string is more outstanding when using on inclined shaft, then can't use on horizontal well; 2. electric submersible pump to the cable and the easy frayed equivalent damage of pump in shaft bottom, in case impaired termination of pumping is difficult to repeated priming, must operation descend pump just can start down again, and task difficulty is big, the expense height.In addition, when running into stratum feed flow deficiency, easily produce heat, burn out the accident of parts such as impeller, guide wheel; 3. Starting mode also exists and same or analogous shortcoming of electric submersible pump or deficiency under the screw bolt well; When 4. pit shaft water liquid level is high, will push down gas, make the gas production inefficiency, even adopt to hold one's breath and, cause operation frequent, cost of production raises.
Three, summary of the invention
The purpose of this utility model provides a kind of multiple tubular pile type bar-free gas-production oil-production device, adopts gas injection device and oil recovery gas production combined string, and the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art improve gas-production oil-production efficient effectively.
Multiple tubular pile type bar-free gas-production oil-production device described in the utility model, comprise gas injection device, adopt water combined string and one way valve, the water combined string is adopted in described oil recovery, comprise the outer oil pipe and the inner oil tube that are lowered in the oil well casing, this inner oil tube lower end is equipped with one way valve, the upper end is the profit outlet, and outer oil pipe lower end is equipped with one way valve, and the upper end is connected with gas injection device; Described gas injection device comprises electromagnetic switch, electromagnetic relief valve, compressor, accumulator that is connected on the outer oil pipe and the gas reservoir that is connected with electromagnetic relief valve with compressor.
Wherein, be connected with the less extension of diameter under the one way valve of described inner oil tube lower end.。
The utility model has following advantage compared with prior art:
1, owing to adopt the gas injection oil production method, get rid of pit shaft ponding, gas production, oil production increase the efficient height.
2, adopt gas injection device and combined string to adopt water, oil pipe oil extraction draining, the poor efficiency of oil well pump, highly energy-consuming problem are avoided in the sleeve pipe gas production.
3, adopt the multiple tubular pile type bar-free gas-production oil-production device, the use of having omitted sucker rod has solved oil-water well eccentric wear problem.
4, accident rate is low, and the production cycle is long, and cost of production is low.
5, use extensively, not only can on straight well, use, and on inclined shaft and horizontal well, use.
6, simplification instrument, operation, safety factor height, energy conservation.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the utility model device.
Five, the specific embodiment
Consult accompanying drawing, a kind of multiple tubular pile type bar-free gas-production oil-production device, comprise gas injection device, adopt water combined string and one way valve, oil recovery is adopted the water combined string and is comprised outer oil pipe 9 and the inner oil tube 8 that is lowered in the oil well casing 7, these inner oil tube 8 lower ends are equipped with one way valve 15, the upper end is profit outlet 5, and outer oil pipe 9 lower ends are equipped with one way valve 15, and the upper end is connected with gas injection device; Gas injection device comprises electromagnetic switch 14, electromagnetic relief valve 4, compressor 2, accumulator 1 that is connected on the outer oil pipe 9 and the gas reservoir 3 that is connected with electromagnetic relief valve 4 with compressor 2.
The one way valve of inner oil tube 8 lower ends is connected with the less extension of diameter 10 for 15 times to keep the enough big liquid capacity in bottom, and sleeve pipe 7 lower ends are artificial bottom of a well 13.
During operation, stratum gas 11 from the tubing and casing annular space through 6 extraction of gas production mouth; Stratum oil and water 12 through the one way valve 15 of outer oil pipe 9 lower ends, enter the combined string annular space.Gas is by the annular space of compressor and accumulator 1 and electromagnetic switch 14 injection inner oil tubes 8 and outer oil pipe 9.Form the closed check valve of high pressure,, will enter the stratum oil and water of combined string annular space, discharge by profit outlet 5 with the one-way valve opens of extension 10 and inner oil tube lower end with outer oil pipe 9 lower ends; After stratum oil and water is got rid of by the amount of certain liquid height, electromagnetic switch 14 is closed, electromagnetic relief valve 4 is opened, gas in the combined string 11 is drained into gas reservoir 3 naturally, pressure by fluid column is closed inner oil tube one way valve 15 simultaneously, make outer oil pipe one-way valve opens by strata pressure, stratum oil and water enters the combined string annular space once more, forms a working cycles thus.
