Abstract
A casing leakage-finding decompression tool comprises a packer, a decompression body, shearing pins, a slide sleeve and sealing rings, wherein the lower portion of the packer is connected with the upper portion of the decompression body, a decompression hole is arranged on the decompression body, the slide sleeve is installed in the decompression body, and is covered on the decompression hole, the sealing rings are installed on the slide sleeve, two sealing rings are installed on the upper portion of the slide sleeve above the decompression hole, and two sealing rings are installed on the lower portion of the slide sleeve below the decompression hole to seal a gap between the slide sleeve and the decompression body, the slide sleeve is fixed on the decompression body through the shearing pins, and the upper inner hole of the slide sleeve is provided with a trumpet for throwing in steel balls to form the sealing to block the inner hole of the slide sleeve. After finding leakage and needing decompression, the slide sleeve can be opened, and liquid in an oil pipe can flow into the casing, thus the spouting phenomenon can be avoided after the oil pipe is decompressed, thereby not polluting environment, and having convenient operation for workers and obvious economic benefits.
Description
Technical field:
The utility model is a kind of oilfield oil well power tool, is that a kind of sleeve pipe is looked for and sewed press tool.
Background technology:
Present oil-water well looks for leakage that instrument is that ball-and-seat is installed under the packer, this supporting can not pressure release, look for Lou finish after during the upper lifting pipe post, liquid in the tubing string can spray on ground, cause environment pollution on the one hand, workman's inconvenience work influences job schedule on the other hand.
Summary of the invention:
The purpose of this utility model is that a kind of sleeve pipe of design is looked for and sewed press tool, can be in sleeve pipe after oil-water well being looked for Lou finish with the liquid earial drainage in the oil pipe, and free from environmental pollution, the workman is easy to operate.
The purpose of this utility model has been achieved in that packer, also by the pressure release body, cut off pin, sliding sleeve, sealing ring and form, the packer bottom is connected with pressure release body top, on the pressure release body relief hole is arranged, sliding sleeve is installed in the pressure release body, sliding sleeve covers relief hole, and sealing ring is installed on the sliding sleeve, and sliding sleeve is fixed on the pressure release body by cutting off pin.
The two seals circle is arranged at sliding sleeve top, and is on the relief hole, and the two seals circle is arranged at the sliding sleeve bottom, and is under the relief hole.
Sliding sleeve upper end endoporus has horn mouth.
The beneficial effects of the utility model are: look for when needing pressure release after Lou finishing, sliding sleeve can be opened, and the liquid in the oil pipe can flow in the sleeve pipe, can not spray after the oil pipe pressure release and carry, and free from environmental pollution, the workman is easy to operate, has remarkable economic efficiency and benefit.
Description of drawings:
Accompanying drawing is an assembling drawing of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment of the present utility model by packer 1, pressure release body 2, cut off pin 3, sliding sleeve 4, sealing ring 5 and form, packer 1 bottom is connected with pressure release body 2 tops, relief hole 6 is arranged on the pressure release body 2, sliding sleeve 4 is installed in the pressure release body 2, sliding sleeve 4 covers relief hole 6, sealing ring 5 is installed on the sliding sleeve 4, two seals circle 5 is arranged at sliding sleeve 4 tops, and be on the relief hole 6, two seals circle 5 is arranged at sliding sleeve 4 bottoms, and be under the relief hole 6, being used to seal the gap between sliding sleeve 4 and the pressure release body 2, sliding sleeve 4 is fixed on the pressure release body 2 by cutting off pin 3.Sliding sleeve 4 upper end endoporus have horn mouth, are convenient to form sealing with the steel ball that drops into, and stop up the endoporus of sliding sleeve 4.
When the upper lifting pipe post needed pressure release after sleeve pipe was looked for and Lou being finished, drop into steel ball in oil pipe, steel ball is landed on the horn mouth of sliding sleeve 4 upper ends, suppresses in oil pipe, the thrust that pressure produces is cut off pin 3 and is cut off, the sliding sleeve 4 descending relief holes 6 that expose make tubing and casing UNICOM, the oil pipe pressure release, can not emit spray to carry oil pipe, the well site is clean, does not pollute, and the workman is easy to operate.
