Description
Technical field
The utility model relates to a kind of downhole operation equipment, and particularly a kind of oil field operation salvages fettling installation.
Background technology
At present, in Petroleum Production, because summer rainwater is large, there will be flood, 13 years there is extraodinary flood in Daqing oil field, and after being forced to stop production, new website operation area daily oil production reduces more than 1/3, the direct Daqing oil field that affects recovers the oil nine factories, recover the oil ten factories and the riverine production operation region of Toutai Oilfield, and a large amount of oil well is forced to close because of water logging.In addition, cause waterlogging because large area continues rainfall, flood inundation on tracks motor-pumped well, the suspended particulate carried secretly in water is deposited in well, and well is silted up, and light deposition thickness is not dark, and serious silt is put down, and oil well, by silt landfill, affects the rapid production of oil well.The sandstone that oil field is filtered in recovery process easily causes the blocking to oil well, often occurs that object falls into the situation of down-hole, and what impact was produced normally carries out.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil field operation to salvage fettling installation, effectively improves sand removal efficiency, improve the efficiency that oil well resumes operation.
Its technical scheme is: comprise tool joint, salvage unit, drill bit, tool joint connects salvages unit, the bottom of described salvaging unit connects drill bit, described salvaging unit comprises fishing socket, the top of described fishing socket connects to carry draws ring, the inside of fishing socket is provided with carries cylinder, valve is fixed in the inside carrying cylinder, described valve is connected with swivel becket by being fixed on the retainer ring carrying cylinder inside, described swivel becket is provided with rotation slide calliper rule, described retainer ring is provided with fixed block, and described fixed block is positioned at the positive lower portion of retainer ring upper ring body.
Above-mentioned rotation slide calliper rule are arc tooth bar.
The beneficial effects of the utility model are: by the closedown of valve, prevent sandstone from revealing, and fishing socket pull-out realizes the removing operation of sandstone; Arrive alluvial face under dragging for sand tube when dragging for sand, repeatedly carry drilling rod, impact silt, make silt enter in fishing socket; Then will drag for sand tube to propose, outside well, to pour out sandstone in pipe; In addition, equipment of the present utility model is simple, and operating efficiency is high, effectively improves sand removal efficiency, improves the efficiency that oil well resumes operation, and ensures the rapid production of oil well, decreases sandstone in oil well production and block the impact caused.

Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the structural representations salvaging unit;
Accompanying drawing 3 is the structural representations carrying cylinder;
Accompanying drawing 4 is syndeton schematic diagrames of valve;
In upper figure: tool joint 1, salvage unit 2, drill bit 3, fishing socket 2.1, carry and draw ring 2.2, carry cylinder 2.3, valve 2.4, retainer ring a, swivel becket b, rotate slide calliper rule c, fixed block d.
Detailed description of the invention
1-4 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises tool joint 1, salvage unit 2, drill bit 3, tool joint 1 connects salvages unit 2, the bottom of described salvaging unit 3 connects drill bit 3, described salvaging unit 2 comprises fishing socket 2.1, the top of described fishing socket 2.1 connects to carry draws ring 2.2, the inside of fishing socket 2.1 is provided with carries cylinder 2.3, valve 2.4 is fixed in the inside carrying cylinder 2.3, described valve 2.4 is connected with swivel becket b by being fixed on the retainer ring a carrying cylinder 2.3 inside, described swivel becket b is provided with and rotates slide calliper rule c, described retainer ring b is provided with fixed block d, described fixed block d is positioned at the positive lower portion of retainer ring b upper ring body.
Rotation slide calliper rule c is wherein arc tooth bar.
Operating principle of the present utility model: fishing socket rotates the bit driven bottom fishing socket, go deep into well inside gradually, the sandstone that bit drills rises is by the inside progressively deeply progressing into fishing socket cylindrical shell of fishing socket, when fishing socket moves downward, the cylinder of carrying of fishing socket inside moves downward, carry valve in cylinder by sandstone jack-up, sandstone enters fishing socket inside, when the inner sandstone of fishing socket reaches maximum capacity, by the hoisting tool at top, fishing socket is pulled out, the valve carrying cylinder inside while pull-out is closed, connect valve swivel becket on rotation slide calliper rule with on retainer ring fixed block card with, block swivel becket to rotate, realize the closedown of valve, prevent sandstone from revealing, fishing socket pull-out realizes the removing operation of sandstone, arrive alluvial face under dragging for sand tube when dragging for sand, repeatedly carry drilling rod, impact silt, silt is entered in fishing socket.Then will drag for sand tube to propose, outside well, to pour out sandstone in pipe.Repeatedly operate, until silt is drawn only in well.
