Abstract
The utility model provides a spiral salvage well rubber instrument that falls, includes top connection, connecting pipe, coil spring, salvage section of thick bamboo connector, single -row entad short cylindrical roller bearing, spiral bit and a salvage section of thick bamboo. Its characterized in that: top connection and spiral bit go up end screw thread connection, salvage section of thick bamboo connector and salvage the periphery of barrel casing at connecting pipe and spiral fishing head, salvage section of thick bamboo connector and go up end screw thread connection with salvaging a section of thick bamboo, the top connection with salvage the connecting pipe between the section of thick bamboo on be equipped with coil spring, be equipped with the single -row cylindrical roller bearing of entad lacking on the upper portion of salvaging the spiral bit between section of thick bamboo connector and the salvage tin. The utility model discloses can pull out the great cubic rubber of diameter is whole, also can twist into the fritter and pull out, reduce the sticking of tool, block up the operating tool string, sand washing, drifting, cover mill the construction and meet and hinder the emergence not less than the scheduling problem. Shorten the operation and accounted for the well cycle, reduced the operating cost.
Description
Technical field
The utility model relates to a kind of oil well repairing operation instrument, and specifically a kind of spiral salvaging falls well rubber instrument.
Background technology
Current oil, well pit shaft drop after block rubber, cause lock of tool drilling, and blocking operating tool string, sand washing, drifting, cover milling work progress can be hampered any more, cause difficulty to job execution.Method processes on-the-spot generally to adopt punching, pressure, mill, milling to rubber process, lose etc., but effect is all undesirable, causes extend duty cycle, cost increase, affects the normal production of oil well.
Summary of the invention
The purpose of this utility model is to provide a kind of spiral salvaging and falls well rubber instrument, overcomes the defect that above-mentioned prior art exists.
Technical scheme described in the utility model is achieved in the following ways:
The utility model comprises top connection, tube connector, helical spring, fishing socket connector, single-row centripetal cylindrical roller bearing, augers and fishing socket.Described top connection is connected with augers threaded upper ends, fishing socket connector and fishing socket are enclosed within the periphery of tube connector and spiral fishing head, fishing socket connector is connected with fishing socket threaded upper ends, tube connector between top connection and fishing socket is provided with helical spring, and the top of the augers between fishing socket connector and fishing socket is provided with single-row centripetal cylindrical roller bearing.
Described top connection is set to cylindrical, and upper diameter is less than lower diameter, and top is provided with male thread, and bottom is provided with box thread, and center is provided with circular hole.
Described fishing socket is set to cylindrical shape, and upper inner diameter is greater than lower inner diameter, is provided with box thread in upper end, is provided with sawtooth in bottom.
Described augers is set to cylindrical, middle and upper part external diameter is greater than upper and lower external diameter, and upper end is provided with male thread or box thread, and male thread bottom is provided with single-row centripetal cylindrical roller bearing, bottom is provided with conical head, is provided with rotates anchor dish and circulation port in lower, outer perimeter.
The utility model has the following advantages: block rubber entirety larger for diameter can be pulled out, also can carry out being twisted into fritter to pull out, decrease bit freezing, blocking operating tool string, sand washing, drifting, cover milling construction are hampered the generation of not inferior problem, shorten operation and account for the well cycle, reduce operating cost.

1-top connection in figure, 2-helical spring, 3-fishing socket joint, 4-single-row centripetal cylindrical roller bearing, 5-augers, 6-fishing socket.
Detailed description of the invention
For disclosing the technical solution of the utility model further, elaborated by embodiment below in conjunction with Figure of description:
The utility model comprises top connection 1, tube connector, helical spring 2, fishing socket connector 3, single-row centripetal cylindrical roller bearing 4, augers 5 and fishing socket 6.Described top connection is connected with augers threaded upper ends, fishing socket connector and fishing socket are enclosed within the periphery of tube connector and spiral fishing head, fishing socket connector is connected with fishing socket threaded upper ends, tube connector between top connection and fishing socket is provided with helical spring, and the top of the augers between fishing socket connector and fishing socket is provided with single-row centripetal cylindrical roller bearing.
Operating principle of the present utility model:
When salvaging well rubber, power is passed to drilling rod by wellhead liquid pressing tongs or hydraulic pump, drilling rod drives top connection tube connector and augers to rotate, fishing socket and fishing socket joint produce elastic rotary under drilling rod Action of Gravity Field simultaneously, the well rubber that lands under the sawtooth effect of fishing socket lower end pierces in fishing socket, fishing socket, under helical spring effect, can prevent from rubber to grind to fall into well, cause the pollution to oil reservoir.The well rubber that falls entered in fishing socket is flutterred by the rotation anchor dish of augers simultaneously and is caught on augers, can flutter under the effect rotating anchor dish catch multiple fall well rubber, and flutter the well rubber that falls caught and turn tighter and tighter, difficult drop-off, the success rate of salvaging well rubber is high.
