As we all know,casing plays an important role in the oilfield industry,but do you have a deep understanding of the casing pipe? Today I will have a detailed introduction of the casing pipe.
There are three different kinds of the casing pipe.They are Surface casing,Intermediate casing and production casing.Surface casing is set to provide blowout protection, isolate water sands, and prevent lost circulation. It also often provides adequate shoe strength to drill into high-pressure transition zones. In deviated wells, the surface casing may cover the build section to prevent key seating of the formation during deeper drilling. This string is typically cemented to the surface.Intermediate casing is often set in the transition zone from normal to abnormal pressure. The casing cement top must isolate any hydrocarbon zones. Some wells require multiple intermediate strings. Some intermediate strings may also be production strings if a liner is run beneath them. Production casing is used to isolate production zones and contain formation pressures in the event of a tubing leak.
What is said above is something about the three different kinds casing.Now do you have a deep understanding of the casing pipe?Whenever you have needs for the casing pipe,you can contact with us,our company can deliever the products that you needed in the first time.
