Problems solved by technology

[0003] The blowout preventer system is the core equipment in the drilling well control device. Although various wellhead blowout preventers can effectively control wellhead blowout and blowout events, it is possible to close the wellhead blowout preventer to prevent fluid flow or control pressure. Will increase the possibility of downhole blowout

Abstract

The invention discloses an underground blowout preventer experiment bench device and an operation method thereof, belongs to the technical field of indoor experiments, and is mainly used in the indoor experiment process of an underground blowout preventer with a rubber sleeve in the oil exploration and development process. The experiment bench device is composed of parts of a bench body structure, a casing lifting device, a pressure applying device and a test casing. In the experiment process, firstly, the underground blowout preventer is installed into the test casing in the casing lifting device, then, an electric hoist is matched with a pulley combination to complete the installation and centering of the underground blowout preventer, the pressure applying device is used for applying hydraulic pressure to cause the rubber sleeve to be loaded and compressed, and finally, drilling fluid is pumped into the test casing to test the sealing effect of the rubber sleeve on the annulus of a drill stem in the deformation condition of the rubber sleeve. The experiment bench device, disclosed by the invention, has the characteristics of labor-saving operation, simple structure and easiness in the observation of rubber sleeve deformation process, and can effectively carry out operation performance testing and display of the underground blowout preventer with the rubber sleeve.

Description

technical field [0001] The invention relates to an experimental technique for carrying out related indoor tests on an underground blowout preventer, in particular to an experimental bench device and an operating method thereof for performing a sealing test and function verification on an underground blowout preventer with a rubber tube. Background technique [0002] In oil and gas exploration and development, with the development of modern oil drilling technologies, such as deep wells, ultra-deep wells, high-pressure oil and gas wells and the development of widely used balanced drilling techniques, especially in the discovery, release and protection of oil and gas layers, it is increasingly In the underbalanced (negative pressure) drilling technology that we pay attention to, due to the high and complicated downhole pressure, if we only rely on ground well control equipment to control the flow of fluid and the pressure in the well during the drilling process, the possibility ...
