Abstract
The utility model relates to a hydraulic jet pump separate zone oil production process pipe string, comprising a well completion casing, a production casing, a tubing string, a hydraulic jet pump, an upper check valve, a plug-in packer, a sand control pipe, a sealing plug, a sliding sleeve switch, a layered packer, a lower check valve and a tubing anchor, wherein the production casing is arranged in the well completion casing, and the upper end of the production casing is provided with a sealer and the plug-in packer; the sand control pipe and the layered packer are arranged under the packer in sequence, and the hydraulic jet pump, the upper check valve, the sliding sleeve switch, the sealing plug, the lower check valve and the tubing anchor are arranged above the tubing string in sequence. The utility model has an original production string which can carry out the separate zone oil production process, high oil well utilization rate, high oil production aging, high output, low production cost, high production efficiency, reliable layering switch, convenient operation and safety and easiness, and is widely applied to the oil production process.
Description
One, technical field
The utility model relates to the oil exploitation down-hole string, particularly a kind of hydraulic jet pump oil production by layer process pipe string.
Two, background technology
The oil exploitation downhole pump process pipe string of usefulness commonly used, as oil extraction process tubular columns such as electric pump sucker rod pumps, shortcoming that it is common or deficiency are exactly that fixed tubular column can not carry out oil production by layer, can not give full play to the strength of each oil reservoir in the well, even produce and pour in down a chimney phenomenon, cause oil well output low, the utilization rate of oil wells is low, exploitation effect is poor, and economic benefit is low, and cost is high to problem.
Three, summary of the invention
The purpose of this utility model provides a kind of improvement hydraulic jet pump oil production by layer process pipe string, adopt the water jet pump flow string, the selective sand control tubing string, the tubular column structure that separate-layer production string three partly combines, the both shortcoming or deficiencies that can overcome effectively or avoid existing in the above-mentioned prior art can reach the purpose of motionless pipe oil production by layer again smoothly.
Hydraulic jet pump oil production by layer process pipe string described in the utility model, comprise completion casing, production casing, tubing string, hydraulic jet pump, last ball-and-seat, the plug-in type packer, anti-sandpipe, sealing plug, sliding sleeve switch, layer separating packer, following ball-and-seat and tubing anchor, it is characterized in that in the described completion casing production casing being installed, the production casing upper end is equipped with sealer and plug-in type packer, install in turn under this packer and be connected with anti-sandpipe, layer separating packer is installed in turn on the described tubing string and is connected with hydraulic jet pump, last ball-and-seat, sliding sleeve switch, sealing plug, following ball-and-seat and tubing anchor.
Wherein, the described above tubing string of ball-and-seat of going up is outside the sealer of production casing upper end, and described tubing anchor is installed in the completion casing under the production casing.The interlayer place of described layer separating packer between each oil reservoir.Described anti-sandpipe is installed in the position of oil reservoir correspondence.Described sealing plug is installed on the top and bottom of layer separating packer respectively.Described upper and lower ball-and-seat is the retrievable structure.Described sliding sleeve switch is installed on the tubing string of each oil reservoir relevant position.
The utility model has following advantage compared with prior art:
1, fixed tubular column can carry out oil production by layer technology;
2, the utilization rate of oil wells, oil production efficiency raising, output height, cost of production are low, the production efficiency height;
3, reliable, easy to operate, safe, the easy row of seam change switch.
