Abstract

The invention relates to the field of petroleum well construction, in particular to an integrated oil and gas well mouth automatic pressure control system which comprises a rotary control head, a first electric valve and an electric throttle valve. The rotary control head is provided with three ports, the first port of the rotary control head is communicated with a wellhead, the second port of the rotary control head is communicated with one end of the first electric valve through a hard pipe, and the third port of the rotary control head is communicated with one end of the electric throttle valve through a hard pipe; and the other end of the first electric valve is connected with the other end of the electric throttle valve through a three-way joint. The whole wellhead pressure control system can be arranged on a wellhead platform through remote control, when pressure control needs to be carried out, the first electric valve is closed, the electric throttle valve is opened and adjusted, and well liquid flows to the vibrating screen and the mud pool through the three-way connector finally, so that the pressure control function is achieved; when pressure control is not needed, the first electric valve is opened, and the electric throttle valve is closed, so that well liquid flows to the vibrating screen and the mud pool through the three-way joint.

Description

technical field [0001] The invention relates to the field of oil well construction, in particular to an integrated automatic wellhead pressure control system for oil and gas wells. Background technique [0002] During the drilling process of oil and gas wells, managed pressure drilling technology is usually used to increase drilling speed and increase efficiency and ensure well control safety. There are hoses, one of which is used for pressure control, which needs to be connected to the manifold equipment, and then connected to the valve control equipment through the hose, and finally flows to the shaker and mud pool; the other hose is also through the manifold The equipment flows to the vibrating screen and the mud pool. The existing equipment is complicated, bulky, expensive, and inconvenient to install and transport. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an integrated automatic wellhead pressur...
