Remote control ball delivery device

Abstract

The invention discloses a remote control ball delivery device. The remote control ball delivery device comprises a ball containing mechanism, a ball storing mechanism, and a hydraulic system. The upper end of the ball containing mechanism communicates with the ball storing mechanism, the lower end of the ball containing mechanism communicates with the hydraulic system, and the device further comprises a remote control mechanism for storing fracturing balls on the ball storing mechanism. According to the remote control ball delivery device, the problem existing in passing through a high-voltagearea by a constructor can be effectively solved, constructor safety coefficient is improved, work continuity is improved, construction cost is reduced, use of fracturing liquid is reduced, the construction success rate is improved, the construction over displacement is solved, independent choice is achieved, work is intelligent, an operator can be thoroughly away from the high-voltage work area,and the high-voltage thorn leakage danger possibly bringing by the high-voltage area is avoided.

Description

technical field [0001] The invention belongs to the field of petroleum engineering, and in particular relates to a remote control ball throwing device used for the staged fracturing process of a ball throwing slip sleeve. Background technique [0002] In oil and gas exploitation, in order to increase production, staged fracturing is carried out, and the staged fracturing process of throwing ball sliding sleeves is usually used in staged fracturing. During the operation, the opening of the sliding sleeve needs to be pumped from the surface into the high-pressure area to load the corresponding sliding sleeve fracturing ball, and the fracturing ball is pumped to the ball seat through the liquid to form a closed space, and the pressure is rapidly increased until the sliding sleeve is opened. In the prior art, workers need to carry the next stage of fracturing balls into the high-pressure area and load them into the ball-throwing device. There are potential safety hazards for wor...

AI Technical Summary

Problems solved by technology

In the existing technology, the staff need to carry the next section of fracturing balls into the high-pressure area to install the ball-throwing device. There are potential safety hazards for the staff to go to and from the high-pressure area, and the construction process cannot be continuous, which wastes fracturing fluid and affects the fracturing effect.
