Abstract

The utility model provides an outer channeling groove lugging device of an oil-water well sleeve. The device is formed by an oil pipe [1], a hydraulic anchor [2], an upper packer [3], a sleeve cement extruding flow controller [4], a lower packer [5] and a check valve [6], wherein the oil pipe [1], the hydraulic anchor [2], the upper packer [3], the sleeve cement extruding flow controller [4], the lower packer [5] and the check valve [6] are connected in sequence. By utilizing the device, cement can be conveniently extruded to an oil well sleeve of a leaked section, so as to conveniently take repairing measures on the damaged oil well sleeve.

Description

The outer channelling plugging device of a kind of Casing Failure

Technical field

The utility model relates to the outer channelling plugging device of a kind of Casing Failure on the oilfield, this device has this device to have oil pipe [1], hydraulic anchor [2], upper packer [3], sleeve pipe squeeze method restriction choke [4], lower packet [5], ball-and-seat [6] to form, use this device easily to the oil well casing squeeze method of leakage section, to be convenient to damaged oil well casing is taked repairing measures.

Background technology

At present, known technology is not have oil well casing squeeze method device, its major defect to be that the casing damage in the oil well is not easy to repair, and causes heavy losses often for Petroleum Production unit in the casing salvaging process of oil well.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of Casing Failure outer channelling plugging device, uses this device can search easily oil well casing and where misses, and is convenient to take corresponding casing salvaging measure.

The technical scheme that its technical problem that solves the utility model adopts is: adopt the outer channelling plugging device of a kind of Casing Failure, this device has oil pipe [1], hydraulic anchor [2], upper packer [3], sleeve pipe squeeze method restriction choke [4], lower packet [5], ball-and-seat [6] forms, it is characterized in that: oil pipe [1], hydraulic anchor [2], upper packer [3], sleeve pipe squeeze method restriction choke [4], lower packet [5], ball-and-seat [6] is linked in sequence, the effect of oil pipe [1] is to carry the liquid that pumps in the well, the effect of hydraulic anchor [2] is fixedly oil pipe and packer, stop upper packer [3] and lower packet [5] that length travel occurs, the effect of upper packer [3] and lower packet [5] is the annular space that envelope is cut oil pipe and sleeve pipe, between two packers, form seal section, the effect of ball-and-seat [6] is only to allow the liquid in the sleeve pipe to enter tubing string, do not allow the liquid in the oil pipe to enter sleeve pipe, use this device easily to the oil well casing squeeze method of leakage section, to be convenient to damaged oil well casing is taked repairing measures.

The beneficial effects of the utility model: by field trial, the utility model compared with prior art uses this device easily to the oil well casing squeeze method of leakage section, to be convenient to damaged oil well casing is taked repairing measures.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified:

(accompanying drawing) is the schematic diagram of the structure embodiment of the outer channelling plugging device of a kind of Casing Failure.

Among the figure: 1. oil pipe; 2. hydraulic anchor; 3. upper packer; 4. sleeve pipe squeeze method restriction choke;

5. lower packet; 6. ball-and-seat; 7. artificial bottom of a well; 8, oil well casing.

The specific embodiment

In the accompanying drawings, adopt the outer channelling plugging device of a kind of Casing Failure, this device has oil pipe [1], hydraulic anchor [2], upper packer [3], sleeve pipe squeeze method restriction choke [4], lower packet [5], ball-and-seat [6] forms, it is characterized in that: oil pipe [1], hydraulic anchor [2], upper packer [3], sleeve pipe squeeze method restriction choke [4], lower packet [5], ball-and-seat [6] is linked in sequence, the effect of oil pipe [1] is to carry the liquid that pumps in the well, the effect of hydraulic anchor [2] is fixedly oil pipe and packer, stop upper packer [3] and lower packet [5] that length travel occurs, the effect of upper packer [3] and lower packet [5] is the annular space that envelope is cut oil pipe and sleeve pipe, between two packers, form seal section, the effect of ball-and-seat [6] is only to allow the liquid in the sleeve pipe to enter tubing string, do not allow the liquid in the oil pipe to enter sleeve pipe, use this device easily to the oil well casing squeeze method of leakage section, to be convenient to damaged oil well casing is taked repairing measures.
