Multi-pressure fracture temporary blocking agent pressure testing device

The present invention relates to a technical field pressure testing apparatus, is a multi-pressure fracture temporary blocking agent pressure test apparatus; pressure vessel which includes a body, an upper cover and a lower plug; pressure at the upper end of the reactor body the upper cover member is fixedly mounted at the lower end of the pressure vessel body is attached to the fixed plug, a cavity is formed between the upper cover body pressure, the pressure vessel and a lower plug, and the pressure chamber has a top cover is connected through the mounting holes, cracks in the lower plug head has pressure bearing chamber communicating with at least one of. The present invention is compact and reasonable structure, convenient to use, by the pressure vessel body, with the top cover, the plug and the intake pressure valve is used, to achieve truly simulate multiple fracture pressure bearing capacity diverting agents in the formation, with good and reliable closure performance characteristics, improve the bearing capacity of the test precision temporary blocking agent, it provides a theoretical basis for fracturing.
