Pressure well manifolds are used to control borehole pressure and usually consist of the main body of the manifold, upstream and downstream valves and ancillary piping. The main body of the manifold consists of multiple valves and valve control systems to meet different operating conditions, while the upstream and downstream valves are used to control the direction of fluid flow in the borehole. In addition, the ancillary piping is also responsible for connecting with other wellhead sockets. Overall, the pressurized tubing manifold is a highly integrated and multifunctional device.
Pressure well manifold is a kind of equipment used in the drilling fluid circulation system, which generally consists of the main body of the manifold, auxiliary valves and pipelines. It is mainly used to control the injection and leakage of drilling fluid to ensure the safety and stability of the drilling process.
Pressurized tubing sink is one of the important equipments in the drilling process, and its main functions are as follows:
1. controlling the circulating pressure: by adjusting the injection and leakage of drilling fluid, the pressurized tubing sink controls the size of the circulating pressure to ensure the stability of the borehole during the drilling process and to prevent the well wall from collapsing.
2. Detecting the condition of the well bottom: The pressure control instrument set in the pressurized tubing sink can monitor the condition of the well bottom, such as the presence of water, gas and other substances at the bottom of the well, as well as the size of the pressure at the bottom of the well, to ensure the safety of drilling.
3. Protecting the integrity of the well wall: During the drilling process, the pressurized tubing manifold can control the injection and leakage of drilling fluid to protect the integrity of the well wall, preventing the collapse of the well wall and other safety accidents.
