DEVICE FOR CAPTURE AND LESSONS FROM PIPE WELLS

摘要

The proposal relates to a fishing devices used for emergency response in wells with pipes, in particular to emergency tools used to retrieve from the well pipes emergency (e.g., continuity sucker rods) by their outer surface for gripping. Device for gripping and extraction tubes from the borehole comprises a housing having a tapered surface and a locking body. The conical surface of the housing are provided with grooves, and the locking bodies are designed as grooved plates installed in these grooves for longitudinal movement thereon. The housing bottom is designed as a reverse funnel. The number of grooves and, respectively, the corrugated plates on each conical surface is not less than two. Application of the device for gripping and extraction tubes from the borehole having a required load and the torque depending on the weight of emergency pipe, in conjunction with reliable and comfortable grip would lead to reducing the time to capture and retrieval of emergency pipe from the well, which ultimately reduce the cost of emergency work.
