Abstract

A recycling device of mud generated during well drilling and well repairing comprises a supporting and stretching frame foundation, a supporting and stretching hydraulic cylinder, a supporting and stretching frame, an opening and closing type clamping mechanism and a mud barrel. The recycling device of the mud generated during well drilling and well repairing is of a bionic arm structure. Only one supporting and stretching hydraulic cylinder is needed to drive a rear supporting and stretching frame body and a front supporting and stretching frame body of the supporting and stretching frame to move at the same time so as to achieve the stretching and folding of the supporting and stretching frame. Compared with an existing recycling device of the mud generated during well drilling and well repairing which is driven by multiple cylinders, the recycling device of the mud generated during well drilling and well repairing has the advantages that the structure is more compact, a control system is simple and higher in reliability, and the centering capacity of the mud barrel is good. Furthermore, due to the fact that the supporting and stretching frame can be folded when the recycling device is not used, the recycling device of the mud generated during well drilling and well repairing has the advantages that occupied space is reduced and influence on working of other tools is reduced when compared with an existing recycling device of the mud generated during well drilling and well repairing which is driven by a single cylinder.

Description

technical field [0001] The invention relates to a drilling and workover mud recovery device, which belongs to the field of drilling into soil layers or rocks. Background technique [0002] In oil and gas and unconventional oil and gas drilling and workover operations, especially when drilling and repairing wells, tripping and dismantling drilling tools, some mud overflows and splashes on the turntable, resulting in messy work sites and great potential safety hazards , At the same time cause mud waste. At present, in order to prevent mud from splashing and reclaim the splashed mud, a mud recovery device is generally used. When working, the mud recovery device is extended to the center of the drilling and workover hole, and folded after completing the corresponding work to avoid affecting the operation of other tools. [0003] At present, there are two kinds of mud recovery devices in use at home and abroad: [0004] The first kind of mud recovery device is driven by multi-...
