Description
Technical field
The utility model relates to a kind of producing well equipment, particularly a kind of oil recovery fishing device.
Background technology
Along with the develop rapidly of oil play in recent years and the raising of technology various aspects, China has become the big country of an outlet oil, has brought the effect of bragging about of considerable pulling force and each large industry in the national economy of economic benefit and social benefit Shang Douwei China.But along with undertaking under the more and more heavier prerequisite of responsibility of oil play, problem and drawback have also appearred in technical elements successively, the oil-water well of one of them salvaging can not be caught up with the development speed of oil play with regard to day by day having there is some drawbacks and the technology of falling behind.Oil-water well is salvaged and is seemed a simple minor matter that is easy to, and when practical operation is salvaged, is not still the so simple of the imagination, and due to oil, (kind of the more and more junks of kind of well is also without identical, and the difficulty of salvaging also constantly increases.
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 oil recovery fishing device is provided, and has improved well recovery efficiency, has improved field output.
Its technical scheme is: comprise salvaging unit, fishing socket, valve, clamping unit, tool joint, tool joint connects salvages unit, described salvaging unit is fixed on the inside of fishing socket, described salvaging unit comprises fishing rod, leading truck, helical blade, drill bit, lifting rod, the outside of described fishing rod is provided with helical blade, described fishing rod is provided with lifting rod, the external stability leading truck of fishing rod, the bottom of fishing socket is valve fixedly, described valve is fixed by being fixed on the clamping unit of fishing socket inside, described clamping unit comprises retainer ring and swivel becket, described swivel becket is provided with tooth bar, described retainer ring is provided with fixed block, described fixed block is positioned at the inner side of retainer ring.
Described swivel becket is provided with locking draw ring, and described locking draw ring connects rope.
The beneficial effects of the utility model are: equipment is simple, and operating efficiency is high, have effectively improved sand removal efficiency, improved the efficiency that oil well resumes operation, guaranteed the rapid production of oil well, reduced sandstone in oil well production and stopped up the impact causing, improve well recovery efficiency, improved field output.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of salvaging unit;
Accompanying drawing 3 is structural representations of clamping unit;
In upper figure: salvage unit 1, fishing socket 2, valve 3, clamping unit 4, tool joint 5, fishing rod 1.1, leading truck 1.2, helical blade 1.3, drill bit 1.4, lifting rod 1.5, retainer ring 4.1, swivel becket 4.2, fixed block 4.3, tooth bar 4.4, locking draw ring 4.5, rope 4.6.
The specific embodiment
1-3 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises salvages unit 1, fishing socket 2, valve 3, clamping unit 4, tool joint 5, tool joint 5 connects salvages unit 1, described salvaging unit 1 is fixed on the inside of fishing socket 2, described salvaging unit 1 comprises fishing rod 1.1, leading truck 1.2, helical blade 1.3, drill bit 1.4, lifting rod 1.5, the outside of described fishing rod 1.1 is provided with helical blade 1.3, described fishing rod 1.1 is provided with lifting rod 1.5, the external stability leading truck 1.2 of fishing rod 1.1, the bottom of fishing socket 2 is valve 3 fixedly, described valve 3 is fixed by being fixed on the clamping unit 4 of fishing socket 2 inside, described clamping unit 4 comprises retainer ring 4.1 and swivel becket 4.2, described swivel becket 4.2 is provided with tooth bar 4.4, described retainer ring 4.1 is provided with fixed block 4.3, described fixed block 4.3 is positioned at the inner side of retainer ring 4.1.
Described swivel becket 4.2 is provided with locking draw ring 4.5, and described locking draw ring 4.5 connects rope 4.6.
Salvage the bit that unit rotational drives fishing socket bottom, go deep into gradually well inside, the sandstone that bit drills rises progressively deeply progresses into the inside of fishing socket cylindrical shell by 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, hoisting tool by top is pulled out fishing socket, when pulling out, carrying the inner valve of cylinder closes, connect tooth bar on the swivel becket of valve and the fixed block card on retainer ring with, blocking swivel becket rotates, realize closing of valve, prevent sandstone leakage, fishing socket is pulled out the removing operation that realizes 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 proposes, outside well, to pour out sandstone in pipe.Operation repeatedly, until silt is drawn only in well.
