Description
Technical field
The utility model relates to a kind of downhole operation equipment, particularly a kind of eccentric fettling installation of salvaging.
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, directly affect Daqing oil field recover the oil nine factories, recover the oil ten factories and the riverine production operation of Toutai Oilfield region, oil wells are forced to close because of water logging in a large number.In addition, because continuing rainfall, large area causes waterlogging, flood inundation on tracks motor-pumped well, and the suspended particulate of carrying secretly in water is deposited in well, and well is silted up, and light deposition thickness is not dark, and serious silt is flat, and oil well, by silt landfill, affects the rapid production of oil well.The sandstone that filter in recovery process in oil field easily causes the obstruction 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, and a kind of eccentric fettling installation of salvaging is provided, and equipment is simple, and operating efficiency is high, has effectively improved sand removal efficiency, has improved 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, carry the fixing eccentric valve in inside of cylinder, described eccentric valve is by being fixed on a side of carrying cylinder, the inner side of carrying cylinder is provided with groove, described groove matches with eccentric valve, described eccentric valve by bearing pin with carry cylinder be connected, one end of eccentric valve is stretched out and is carried cylinder by draw ring cylinder lever connecting rod, the other end of eccentric valve matches with the inwall of carrying cylinder.
The above-mentioned inwall of carrying cylinder is provided with the limiting convex block matching with eccentric valve.
The lower end of above-mentioned eccentric valve is provided with block with the junction of carrying an inwall.
The beneficial effects of the utility model are: equipment is simple, and operating efficiency is high, have effectively improved sand removal efficiency, have improved the efficiency that oil well resumes operation, and ensure the rapid production of oil well, have reduced sandstone in oil well production and have stopped up the impact causing.

Accompanying drawing 2 is structural representations of salvaging unit;
Accompanying drawing 3 is syndeton schematic diagrames of eccentric valve;
In upper figure: tool joint 1, salvaging unit 2, drill bit 3, limiting convex block 4, block 5; Fishing socket 2.1, carry and draw ring 2.2, carry cylinder 2.3, eccentric valve 2.4, bearing pin 2.5, draw ring 2.6, pull bar 2.7.
Detailed description of the invention
1-3 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, carry the fixing eccentric valve 2.4 in inside of cylinder 2.3, described eccentric valve 2.4 is by being fixed on a side of carrying cylinder 2.3, the inner side of carrying cylinder 2.3 is provided with groove, described groove matches with eccentric valve 2.4, described eccentric valve 2.4 by bearing pin 2.5 with carry cylinder and 2.3 be connected, one end of eccentric valve 2.4 is stretched out and is carried cylinder 2.3 by draw ring 2.6 cylinder lever connecting rods 2.7, the other end of eccentric valve 2.4 matches with the inwall of carrying cylinder 2.3.
The above-mentioned inwall of carrying cylinder 2.3 is provided with the limiting convex block 4 matching with eccentric valve 2.4.
The lower end of above-mentioned eccentric valve 2.4 is provided with block 5 with the junction of carrying cylinder 2.3 inwalls.
Operating principle: fishing socket rotates the bit that drives fishing socket bottom, go deep into gradually well inside, the sandstone that bit drills rises is by the inside that progressively deeply progresses into fishing socket cylindrical shell of fishing socket, when fishing socket moves downward, the cylinder of carrying of fishing socket inside moves downward, carry eccentric valve in cylinder by sandstone jack-up, sandstone enters fishing socket inside, when the inner sandstone of fishing socket reaches maximum capacity, hoisting tool by top pulls out fishing socket, when pull-out, carrying the inner eccentric valve of cylinder closes, prevent sandstone leakage, fishing socket pull-out realizes the removing operation of sandstone, while dragging for sand, will drag under sand tube and arrive alluvial face, repeatedly carry drilling rod, impact silt, silt is entered in fishing socket.Then will drag for sand tube and propose, outside well, to pour out sandstone in pipe, operation repeatedly, until silt is drawn only in well.
