Abstract
The utility model discloses an under well multifunctional fishing tool for the petroleum industry which is applicable to a workover operation for oil well, gas well and water well, and operations of downhole articles fishing, well drifting and sand washing. The tool consists of an upper joint, a fishing rod, etc., wherein, a pipe base and the fishing rod are connected by a twisting joint, and a connecting stop ring, a guide hole caliper and a connection sleeve are arranged out of the pipe base. A bottom end of the fishing rod is a conical claw which can be inserted into a rubber sheet or other flexible materials to grasp the downhole articles firmly. The tool has a function of a drift size gauge tool, when excessive sands are deposited at the bottom of a well, a circulation channel formed by a tubing-casing annulus and the pipe base can be used for a reverse circulation sand washing operation.
Description
The utility model relates to the mining equipment of petroleum industry, and fishing tool is used in particularly a kind of down-hole more, is applicable to the workover treatment of oil, gas, well, salvages trouble of lost tool in hole, drifting and sand washing operation.
At present, at the exploitation scene of petroleum industry, the situation that object falls into the down-hole often takes place in oil well in process of production, and what influence was produced normally carries out, and will carry out fishing this moment.Present fishing tool is to connect fishing socket in the lower end of down-hole string, and the inwall of fishing socket has 4 elasticity of inwardly stretching out to salvage sheet, when fishing socket touches junk, continues the test tubing string, makes flexure strip block junk and takes oil well out of.Though this instrument is simple in structure, when the long-pending sand in shaft bottom too much or junk partially the time, flexure strip is difficult for pulling out junk, and in taking the process of oil well out of, junk is easily run into the borehole wall and come off.This instrument is not suitable for salvaging similar junks such as wire rope in addition, and fishing success ratio is lower, causes the cost of production height, and operating efficiency is poor.
The purpose of this utility model is to make the down-hole to use fishing tool, the shortcoming of overcome fishing tool function singleness in the prior art, salvaging weak effect more.Make this tool set salvage the interior junk of well, sand washing milling, drifting function, reduce construction technology and corollary equipment, reduce production costs and working strength of workers, increase economic efficiency in one.
The present technique solution can reach above-mentioned purpose: fishing tool is used in the down-hole more, is made up of top connection and adapter sleeve etc., and central tube is connected by the torsion pass joint with fishing rod, its outer connection baffle ring, guiding hole caliper and adapter sleeve.
After using the utility model, fishing tool can be used for the down-hole kinds of processes: drifting, sand washing milling and salvaging junk.Simplify construction sequence and corollary equipment, improved job success ratio, alleviated working strength of workers, reduced cost of production.The utility model is the best to salvage in the well flexible material such as rubber, also can salvage hard materials such as steel wire, grabs that to drag for junk solid reliable, salvaging efficient height.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, fishing tool is used in the down-hole more, be made up of top connection 1, adapter sleeve 9 and fishing rod 10 etc., central tube 3 is connected by torsion pass joint 6 with fishing rod 10, its outer connection baffle ring 5, guiding hole caliper 7 and adapter sleeve 9.Top connection 1 and adjustable ring 2, guiding hole caliper 7 is threaded with baffle ring 5 and adapter sleeve 9 usefulness and fixes with screw.Spring 4 is loaded between adjustable ring 2 and the baffle ring 5, outside the central tube 3; Central tube 3 two ends are pyramidal structure, are attached thereto the top connection 1 of cooperation and the part internal diameter of torsion pass joint 6 and are corresponding conical internal cavity.The outer radius of torsion pass joint 6 is provided with the torsion pass keyway, interior dress torsion pass key 8; The internal diameter of guiding hole caliper 7 is axially arranged with slideway, and torsion pass joint 6 is connected by torsion pass key 8 with guiding hole caliper 7.Torsion pass key 8 can transmit torque and can drive the core that forms with central tube 3, torsion pass joint 6 and fishing rod 10 and slide up and down along the slideway on the guiding hole caliper 7.After making adapter sleeve 9 contact junks, core continues descending, spring 4 is compressed and makes fishing rod 10 stretch out adapter sleeve 9, allow the sharp pawl 11 of fishing rod 10 stab junks such as rubber, and after fishing rod 10 drags for junk, push away adjustable ring 2 on spring 4 releases energy, exercise the junk that adapter sleeve 9 encases fishing rod 10 salvagings on the central tube 3 thereby drive.Adapter sleeve 9 bottoms are the taper claw-like.Fishing rod 10 for hollow tubular, bottom be provided with the crowfoot of falling the pawl several, crowfoot is pulled out for the fishing rod body and is formed or fixed processing in addition, as: welding, crowfoot is fixed or the like with screw, this accompanying drawing is that body is pulled out.The sharp pawl 11 of fishing rod 10 bottoms is a conical claw shape, easily inserts flexible materials such as rubber.On the fishing rod 10 several are the open crowfoot of falling the pawl outwards, can be firm drag for flexible material such as rubber.This instrument also has the function of drift size gauge tool, can check hole diameter to have or not distortion.Can amass in addition sand in the shaft bottom when too much, utilize the circulation canal of oil jacket annular space and central tube 3 formation to carry out the inverse circular sand washing adapter operation.
