Testing device for bridge plug setting test

Abstract

The invention relates to a testing device for a bridge plug setting test. An upper joint of a mechanical pressure testing unit is provided with three upper pressure transmitting holes including a screw plug port, a pressure transmitter connector and an inflating port. The inflating port is connected with a pneumatic pressure pump and an air pump. The right end of the mechanical pressure testing unit is connected with a bridge plug pressure bearing test unit and an electronic pressure test monitoring device. The electronic pressure test monitoring device is connected with a lower joint. The electronic pressure test monitoring device is provided with three lower pressure transmitting holes including a screw plug port, a pressure transmitter connector and a pressure release port. By adoptingthe device provided by the invention, the to-be-tested bridge plug or bridge plug setting tool is placed into a sleeve of the bridge plug pressure bearing unit. The pneumatic pressure pump or the airpump is driven, and high pressure liquid is injected from the inflating port and is then released from the pressure release port after ignition, setting and ball delivery of the bridge plug. The pressure transmitter records pressure change curves, analyzes the pressure change curves output by different units and obtains parameters and conclusions. The device provided by the invention is convenientto mount and dismount, wide in application and easy for promotion and application.

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 plug and tools The performance indicators of the setting tool, such as temperature resistance, pressure resistance, damage resistance during slips and pumping, long-term working stability, etc., have been unable to meet the deeper well depth and bottom hole pressure of Fuling Phase II deep shale gas wells. Larger, higher temperature construction requirements
