Problems solved by technology

With the development of downhole blowout preventers in recent years, although there are various forms of blowout preventers, there are still many imperfections in terms of technology, and a large number of experiments are required in terms of functional stability. Designers need to A large number of experiments have verified the design results. Knowing the relevant working parameters of downhole blowout preventers is of great significance for new well control tools. However, there are few experimental devices for downhole blowout preventers. The experimental bench can quantitatively understand the working parameters of a certain downhole blowout preventer, and these parameters will be an important basis for evaluating the quality of the blowout preventer

Abstract

The invention discloses a down-hole annular blowout preventer experiment bench, belongs to the technical field of down-hole annular blowout preventing experiments, and is mainly used for experiments of down-hole annular blowout preventers. The experiment bench is composed of a frame part, a testing rubber barrel pressure part, a pressure device part and a drive blowout preventer rotating part. The frame part comprises I-shaped steel, rolling wheels and rolling wheel mounting plates; the testing rubber barrel pressure portion comprises a pulley block, a guy cable, sleeves, sleeve lower connectors, gut cable hooks, observation holes, a high-pressure liquid inlet, sealing pieces and rubber barrels; the pressure device part comprises a hydraulic cylinder, a bearing plate, a tension spring, thrust ball bearings, an upper spring connecting block and a lower spring connecting block; the hydraulic cylinder is fixed in the I-shaped steel, and two spring connecting blocks are matched with the thrust ball bearings; and the drive device is formed through spline transmission or belt transmission or friction wheel transmission. The down-hole annular blowout preventer experiment bench is simple in structure and capable of effectively measuring imposed pressure and packing pressure when the annular blowout preventer works.

Description

technical field [0001] The invention relates to an experimental technology of an annular blowout preventer in a downhole. Background technique [0002] Drilling plays a pivotal role in the process of oil exploration and oil field development. Drilling technology is an important link in the exploration and exploitation of oil and natural gas resources, and an important means of oil exploration and development. During the drilling process, when drilling into oil and gas layers, if the bottom hole pressure is lower than the formation pressure, the formation fluid will enter the wellbore. After a large amount of formation fluid enters the wellbore, well kicks, blowouts, and even fires may occur. lead to major accidents. [0003] The blowout preventer is an essential safety facility in the oil drilling process, and it can be divided into wellhead blowout preventer group and drill string blowout prevention tool according to its different functions. According to the needs of actu...
