Intelligent electro-hydraulic remote control pitching device

Abstract

The present invention relates to the field of drilling operation equipment, and provides an intelligent electro-hydraulic remote control pitching device, including: a base, an explosion-proof electric control cabinet, a hydraulic pump station, a high-pressure combined gate valve, and multiple groups of pitching units; each group of pitching units includes: A ball counting device and a ball throwing device; the feeding port of the ball dropping device is connected to the input end of the ball counting device; the high-pressure combined gate valve includes: a main valve body and a primary high-pressure gate connected together through the main valve body valve and a secondary high-pressure gate valve; the axis of the main valve body is hollow; the primary high-pressure gate valve is close to the ball output end of the high-pressure combined gate valve, and the secondary high-pressure gate valve is close to the high-pressure combined gate The ball-throwing input end of the plate valve; a ball-holding cavity is formed between the first-stage high-pressure gate valve and the second-stage high-pressure gate valve; the ball-throwing output end of the high-pressure combined gate valve is connected with the high-pressure fracturing pipeline connection. The invention can improve the safety, reliability and production efficiency of the temporary blocking ball throwing operation.

Description

technical field [0001] The invention relates to the field of drilling operation equipment, in particular to an intelligent electro-hydraulic remote control ball throwing device. Background technique [0002] At present, in the fracturing operation of the oil drilling industry, it is necessary to put the degradable temporary plugging ball for fracturing acidification into the high-pressure fracturing pipeline. Plugging the perforation blasthole in the high-permeability layer forces the working fluid to divert to the low-permeability layer for reconstruction. After the construction is completed, it will be hydrolyzed into a water-soluble mixture and discharged together with other liquids, so as to achieve a clean transformation of the formation, realize vertical physical layering transformation, and reduce the risk of surface process blockage, which is required in the testing and completion stages use. [0003] Most of the current pitching methods of temporary plugging balls...
