Abstract
The utility model discloses a shearing release connector for a continuous pipe, which is designed for achieving the purpose that the continuous pipe can be safely separated from a downhole tool when being clamped during operation. The shearing release connector is characterized in that the outer wall of the necking section of an upper connector is provided with a shear pin inserting groove and a sealing groove; the upper end of a lower connector is provided with a shear pin hole through which shear pins can penetrate; the outer wall of the lower end of the upper connector is provided with symmetrical arc-shaped inserting grooves; the outer wall of the top end of the lower connector is provided with arc-shaped inserting blocks; and the upper connector and the lower connector are in butt joint through the arc-shaped inserting grooves and the arc-shaped inserting blocks. The shearing release connector disclosed by the utility model is suitable for various operations of the continuous pipe; when the shearing release connector is in use, the upper connector is connected with a connector of the continuous pipe, and the lower connector is connected with the downhole tool; and when the shearing release connector is clamped during the operation, the shear pins can be sheared by utilizing a pitching or differential method so that the upper connector is safely separated from the lower connector, and therefore the treatment difficulty of downhole accidents is lowered. The shearing release connector disclosed by the utility model has the advantages of suitability for the small-size range operation of the continuous pipe and an oil through pipe, simple tool structure, agility convenience for operation and torsion transfer function and can achieve flexible and controllable operation by determining the number of the shear pins according to the condition of downhole operation and reliable work by realizing a disassembling effect in the pitching or differential way.
Description
Technical field
The utility model relates to a kind of continuous-tube and shears releasing-joint, belongs to continuous-tube well workover underground operation tool technical field.
Background technology
Because the particularity of continuous-tube operation, and the disconnecting means that conventional oil pipe workover treatment is used is different from the operation mechanism of continuous-tube, makes conventional oil pipe can't be applicable to the continuous-tube operation of oil pipe.In order to satisfy the particularity requirement of continuous-tube size, connected mode and operation mechanism, need special design to be applicable to the continuous-tube disconnecting means.
Summary of the invention
The purpose of this utility model is to provide a kind of continuous-tube to shear releasing-joint, cuts off shear pin when it can make continuous-tube meet card in operation, realizes the safe escape of continuous-tube and downhole tool.
Concrete technical scheme of the present utility model is as follows:
This device tubular top connection bottom undergauge section outer wall is provided with shear pin slot and the sealed groove that is connected sealing ring, and tubular lower contact upper end is provided with shear pin hole interspersed shear pin, that aim at top connection shear pin slot.Tubular top connection lower end outer wall is provided with symmetrical arc slot, and tubular lower contact top outer wall is provided with the arc inserted block corresponding with top connection arc slot.Top connection is docked by arc slot and arc inserted block with lower contact.
The utility model continuous-tube is sheared releasing-joint can adapt to the range of small operation that continuous-tube is crossed oil pipe, and tool construction is simple, and is easy to operate.Upper and lower joint is realized differential docking, has the function of transmitting torque.Can determine shear pin quantity according to the underground work situation, make operating flexibility controlled.Can realize shirking effect by pitching or differential mode, make work more reliable.

The specific embodiment
Further specify referring to figs. 1 through 6 couples of embodiment of the present utility model:
Embodiment:
This device tubular top connection 1 bottom undergauge section outer wall is provided with shear pin slot 12 and the two seals groove 13 that is connected sealing ring 3, and tubular lower contact 4 upper ends are provided with shear pin hole 42 interspersed shear pin 2, that aim at top connection shear pin slot 12.Tubular top connection 1 lower end outer wall is provided with two symmetrical arc slots 11, and tubular lower contact 4 top outer walls are provided with two the arc inserted blocks 41 corresponding with top connection arc slot 11.Top connection 1 is docked by arc slot 11 and arc inserted block 41 with lower contact 4.
The utility model is applicable in the various operations of continuous-tube, such as the not Operating Pressure that reaches with pressure such as sand washing, well-flushing, salvaging, brill milling.After the ontology tool assembling, top connection 1 is connected with the connector of continuous-tube before using, with lower contact 4 connecting downhole instruments, can carries out the continuous-tube workover treatment under the lower going-into-well.When in operation, meeting card, can utilize pitching or differential method to cut off shear pin 2, make top connection 1 safe escape lower contact 4, to reduce the intractability of down-hole accident.
