Abstract

The invention discloses an automatic ball delivering device used for perforating and fracturing continuous operation. The automatic ball delivering device used for perforating and fracturing continuous operation comprises a ball delivering component, a frame body, a rotating device and a supporting rod; the ball delivering component is arranged at one end of the frame body; the other end of the frame body is connected with the supporting rod through the rotating device; the ball delivering component comprises a ball partition rotating cylinder, a rotating cylinder protecting cover, a ratchet wheel, a shifting pin, a driving device and a check pawl; during working, a working end of the driving device expands and retracts for one time, the shifting pin pushes the ratchet wheel to rotate under the cooperation of the check pawl, the ratchet wheel drives the ball partition rotating cylinder to rotate, and the rotating angle is an angle between axes of two adjacent ball partition grooves. According to the automatic ball delivering device used for perforating and fracturing continuous operation, the working efficiency is effectively enhanced, the automatic ball delivering device is beneficial for guaranteeing the fracturing construction quality and effect, personnel climbing is reduced, workers can be prevented from entering into a high pressure area, the safety risk is furthest reduced, fracturing balls can be delivered under a pressure, and double purposes of realizing safety operation and reducing the engineering cost are finally achieved.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery, in particular to an automatic ball-throwing device for continuous operation of perforation and fracturing. Background technique [0002] In the production and development of low-permeability oil and gas fields and shale gas fields, since there are multiple reservoirs in the formation, each reservoir needs to be exploited in one or more stages, so staged fracturing is required, and multi-stage ballistic staged fracturing is used Construction process to open the sliding sleeve. In the staged fracturing process, after putting in the bridge plug to seal, manually board the operation platform, and manually put the fracturing ball into the wellhead. At this time, the wellhead must perform pressure relief operation as required. The fracturing can only be carried out after the pitching personnel get off the stage safely. The pitching process is complex, discontinuous, time-consuming and labo...
