Testing device for bridge plug setting test

Abstract

The invention relates to a bridge plug setting test device. The upper joint of the mechanical pressure test unit has three upper pressure holes, a wire plugging port, a pressure transmitter port and a pressurizing port, and the pressurizing port is connected to a pneumatic pressure pump or Air pump; the right end of the mechanical pressure test unit is connected to the bridge plug pressure test unit and the electronic pressure test monitoring device. The electronic pressure test monitoring device is connected to the joint. The pressure relief port has three lower pressure transmission holes. With the present invention, put the bridge plug to be tested or the bridge plug setting tool into the bushing of the bridge plug pressure test unit of the present invention; drive the pneumatic pressure pump or air pump, and inject high-pressure liquid from the pressurization port to complete the bridge. After the ignition, setting and ball throwing operations of the plug, it is released from the pressure relief port; the pressure change curve is recorded by the pressure transmitter, and the parameters and conclusions are obtained by analyzing the pressure change curve output by each unit. The invention is convenient to assemble and disassemble, has wide applicability and is easy to popularize and apply.

Description

technical field [0001] The invention relates to the field of shale gas well pumping bridge plug staged perforation operations, in particular to a bridge plug setting test and testing device that usually cooperates with cable operations. Background technique [0002] Pumped bridge plug staged perforation is a main method of shale gas development, in which the performance of bridge plugs and setting tools greatly affects the pumping link and fracturing effect. The performance of the setting tool (powder type, electro-hydraulic type), the sealability, stability, and pressure resistance of the bridge plug are all direct and important factors. With the development of shale gas development technology, new tools and new bridge plugs continue to appear. The second phase of deep shale gas development in Fuling is facing a high temperature and high pressure environment. The existing bridge plugs and tools are gradually exposed to the following problems during the application process:...

Problems solved by technology

The second phase of deep shale gas development in Fuling is facing a high temperature and high pressure environment. The existing bridge plugs and tools are gradually exposed to the following problems during the application process: the product quality is not stable, which leads to the midway setting of the bridge plug during pumping; the existing bridge pl
