API casing tubing

The API casingis generally used for the borehole wall support in the drilling as well as after the completion of a well, so as to make sure the smooth running of the drilling process and also the normal procedure of the whole oil well after well completion. As a result of the advancement in recent years, making use of the product is much more substantial. It is generally utilized in oil, gas, coal bed methane, water system, thermal electrical power generation, hydropower penstock, thermal electrical power generation, dredging design, as well as other sectors.

这种产品一般是利用光滑的钢质管道为原料的产品。一些大口径及特殊壁厚项目使用直缝管的管道的身体。该机构应当具有在两端螺钉串进行处理。一端连接到结合，而另一端配备有串保护。线程以及耦合链路壳体之间被使用。此外，各种钢的品质的管体应该对应于不同的接头。

According to the function of well cementation and also the feature of casing, the item down right into a well can be mostly divided into the surface area, intermediate, and also manufacturing types.

1. Surface area casing: The setting depth varies from 10s of meters to hundreds of meters. It depends upon different developments.
2. Intermediate casing: It is used for securing the facility development, so about make certain the smooth running of boring. It can separate huge sector lost-circulation area, stressful water layer, significant collapse strata, in addition to non-target layer of oil or gas, and so on
3. Production casing: It is used to divide the gas, water, or oil layer of different stress from various other strata, so regarding create the oil as well as gas stations. This guarantees the long-lasting production as well as satisfies the extraction and also stimulation needs.

The API tubingis defined as a pipe that drops right into the wells for the production or injection of fluids. In oil expedition, it drops hole to remove underground oil or gas, depending on threaded link. It normally travels through the oil casing, which plays a role of protection and also seclusion.

The tubing dimension in API standard is 1.05 “- 4 “. Our manufacturing array is 2 3/8 “- 4 1/2″ (60.32 mm – 114.3 mm). The pipe produced within this variety is used most regularly in oil and also gas exploration.

The API casing is mostly made use of for the borehole wall surface assistance in the drilling and also after the conclusion of a well, so as to make certain the smooth operating of the boring process and the regular procedure of the entire oil well after well conclusion. It is mostly made use of in petroleum, all-natural gas, coal bed methane, water supply, thermal electrical power generation, hydropower penstock, thermal power generation, digging up engineering, as well as various other markets.
