Abstract
The invention discloses a quick fluid-discharge technology in the petroleum industry, a fluid-discharge device is quickly delivered downwards to a presetting location in the pit by a continuous steel wire rope, the fluid-discharge device is composed of a sealing device, an integrated sucking pump and a liquid inlet screening pipe, the integrated sucking pump is driven to move in a reciprocating way by the power which is supplied by the steel wire rope, thereby realizing the quick flowback of fluid in the pit. A construction operation method of continuous and quick back-flowing of the fluid in the pit to the ground is realized by the quick fluid-discharge technology, and the quick fluid-discharge technology has the characteristics of simple construction, fast speed, high efficiency and low operation cost. The quick fluid-discharge technology can be widely applied to the continuous and quick fluid-discharge of an oil (water) well.
Description
Technical field:
The invention belongs to oil (water) well array liquid technology, particularly a kind of quick fluid-discharge technology is used for the producing well of petroleum industry, continuously lifting liquid fast.
Background technology:
In the field produces, when measures such as enforcement oil (water) well underbalance perforating, acidifying, de-plugging, pressure break,, construction processing liquid need be drained into ground from the down-hole for reducing to the secondary pollution of oil (water) layer.Discharge opeing technology at present commonly used mainly contains two classes: a class is to be lowered to instrument such as swab in down-hole oil tube, driving swab by drifting equipment pumps, down-hole liquid is drained into ground, but the restriction of swab depth of setting owing to be subjected to pumping, this technology have, and efficient is low, lifting depth as shallow, the halfway problem of discharge opeing.Second class is to adopt the gaslift method that well liquid is lifted to ground, as in well, injecting media such as pressure-air or liquid nitrogen, instruments such as supporting down-hole gas lift valve, utilize low-gravity gas in uphill process, liquid in the well to be lifted to ground, supporting and ground construction equipment complexity, expense height that such technology is implemented can not be applicable to the needs of multiple discharge opeing simultaneously.
Summary of the invention:
The purpose of this invention is to provide a kind of quick fluid-discharge technology, comprise the down-hole continuous liquid-discharging device, by continuous wire rope the down-hole continuous liquid-discharging device is transferred to the precalculated position, down-hole fast, and drive down-hole continuous liquid-discharging device work, the row of returning fast that realizes liquid in the well by wire rope.
The objective of the invention is to reach like this: wire rope drives the pumping equipment of being made up of sealer, integrated suction pump, feed liquor screen casing continuously, transfer to the precalculated position, down-hole fast, the precalculated position is determined by the locating ring that is installed on the oil pipe, sealer is by having the elastic sealing element of self sealss characteristic, with the oil pipe spatial separation is upper and lower two parts, integrated suction pump is made up of pump barrel, plunger, and the feed liquor valve is arranged at the pump barrel bottom, and tapping valve is arranged on the plunger.During work, the plunger of rope belt movement and motor-driven integrative suction pump pumps, and when plunger was up, tapping valve was closed, the feed liquor valve is opened, and finishes imbibition, and when plunger was descending, tapping valve was opened, the feed liquor valve cuts out, and finishes discharge opeing, and the continuous lifting that has realized liquid in the well that moves in circles like this drains into ground.
The present invention has designed a kind of oil (water) well down-hole liquid and has returned the technology that drains into ground continuously fast, has following significant effect:
1, the pumping equipment that adopts continuous wire rope to be made up of sealer, integrated suction pump, feed liquor screen casing is transferred to the down-hole fast and is installed on locating ring position on the oil pipe, has improved operating speed and efficient;
2, the elastic sealing element that has the self sealss characteristic by sealer is upper and lower two parts with the oil pipe spatial separation, has set up the lifting passage of discharging liquid;
3, the pump barrel of integrated suction pump keeps static relatively under sealer frictional force and bottom tubing string deadweight effect, can form relative motion with integrated suction pump plunger;
4, firm continuously silk rope provides power, drives integrated suction pump plunger iterative motion, has realized that the quick continuously of liquid discharged in the well, until being lifted to ground.
A kind of quick fluid-discharge technology has been realized the row of returning fast continuously to liquid in the well, and easy construction, speed is fast, efficient is high, running cost is low.The present invention can be widely used in the operations such as underbalance perforating, the de-plugging of oil (water) well acidizing, oil (water) lamination split, oil well formation testing, satisfies the down-hole liquid needs of the row of returning fast continuously.
Description of drawings:
Accompanying drawing is the structural representation of down-hole of the present invention continuous liquid-discharging device.
The specific embodiment:
Below in conjunction with embodiment the present invention is done further detailed description: as shown in drawings, sealer 1 bottom connects integrated suction pump 2, feed liquor screen casing 3 being connected in one suction pumps 2 bottoms, form pumping equipment by sealer 1, integrated suction pump 2, feed liquor screen casing 3, integrated suction pump 2 is made up of pump barrel 4, plunger 5, feed liquor valve 6 is arranged at the pump barrel bottom, and tapping valve 7 is arranged on the plunger, and wire rope 8 is connected with integrated suction pump plunger continuously.During construction operation, by continuous wire rope pumping equipment is transferred to the precalculated position, down-hole continuously fast, the precalculated position is determined by the locating ring 10 that is installed on the oil pipe 9, sealer 1 is by having the elastic sealing element of self sealss characteristic, with the oil pipe spatial separation is upper space 11, lower space 12 two parts, and upper space 11 is for discharging the lifting passage of liquid.During continuous draining, wire rope 8 drives integrated suction pump 2 motions, when plunger 5 was up, tapping valve 7 was closed, and feed liquor valve 6 is opened, liquid enters in the integrated suction pump pump barrel 4 in the well, when plunger 5 was descending, tapping valve 7 was opened, and feed liquor valve 6 cuts out, liquid in the integrated suction pump pump barrel is upwards discharged through outage 13, moves in circles like this to have realized that the continuous lifting fast of liquid drains into ground in the well.
