Description

Knotting device of temporary rope knot blocking agent and temporary rope knot blocking agent structure Technical Field The utility model belongs to the technical field of temporary plugging agents for oil and gas wells, and particularly relates to a knotting device for a knotting temporary plugging agent and a knotting temporary plugging agent structure. Background The temporary plugging agent is a key plugging material in the temporary plugging and fracturing technology of the oil and gas well, and mainly realizes the temporary plugging of cracks or leakage layers by forming a high-strength degradable rope knot structure in a shaft, so that pressure support is provided for subsequent fracturing operation, and finally the temporary plugging agent is degraded and discharged along with flowback fluid. At present, the preparation of the temporary plugging agent for rope knot is highly dependent on manual knot tying or simple manual clamps, and has the problems of low efficiency, poor knot consistency, unstable mechanical property and the like, so that the large-scale application of the temporary plugging fracturing process is severely restricted; After the multi-ring winding forming of the rope knot temporary plugging agent is finished, the rope yarns and the forming knot body are separated through a cutting mechanism to finish the preparation of the single temporary plugging agent, but at the cutting moment, the formed winding wire group is easy to cause the problems of integral loosening, dislocation of the ring, loosening of the joints and the like due to the loss of continuous tension constraint and end clamping, so that the mechanical strength and plugging performance of the knot are greatly attenuated, and the use requirement of high-pressure temporary plugging of an oil-gas well cannot be met; After the multi-ring winding forming of the temporary plugging agent is finished, the ropes and the forming knot body are separated through the cutting mechanism, so that the preparation of the single temporary plugging agent is finished, free rebound and scattering can occur at the cutting moment due to the fact that the tail ends of the remaining to-be-processed ropes are lost, and before the next knotting operation, the scattered ropes are required to be combed again and rotated for homing by a manual or auxiliary mechanism, so that the thread ends are restored to a flexible state convenient for clamping and winding, the production efficiency is greatly reduced, the consistency of the knot is difficult to control due to manual intervention, the fatigue and strength reduction of the rope fibers are easily caused by repeated rotation and carding, and the finished product qualification rate of the temporary plugging agent is further affected. Disclosure of utility model Aiming at the problems that the tail ends of the rest wire groups to be processed in the prior art are free to rebound and scatter due to the loss of fixation, and the scattered wire groups are required to be re-carded, rotated and reset by a manual or auxiliary mechanism before the next knotting operation, so that the wire ends are restored to a flexible state which is convenient for clamping and winding, the production efficiency is greatly reduced, the knot consistency is difficult to control due to manual intervention, the fatigue and the strength reduction of the wire fibers are easy to be caused by repeated rotation and carding, and the yield of finished products of temporary plugging agents is further influenced, the utility model provides the following technical scheme: a knotting device for knotting temporary plugging agent comprises a body, a first handle and a second handle, wherein the body is of an L-shaped structure; The cylinder is fixedly arranged on the end face of the machine body; The lifting plate is arranged at the movable end of the air cylinder and is formed by combining a mounting plate, a pneumatic piston and a positioning plate, the mounting plate is fixedly arranged at the movable end of the air cylinder, the pneumatic piston is arranged at the end part of the mounting plate, and the movable end of the pneumatic piston is provided with two positioning plates; The support column is arranged between the two positioning plates in a penetrating way and is movably connected with the lifting plate; a placing plate fixedly arranged on one end face of the machine body; And the clamping structure is fixedly arranged in the lifting plate and used for clamping and positioning the rope cutting part.
