API 5L Casing Steel Pipes Casing can be divided into: conduit, surface casing, technical casing and reservoir casing.
use
Oil casing is a kind of large diameter pipe, which plays a role in fixing the wall or hole of oil and gas well.Casing is inserted into the wellbore and secured with cement to help separate the rock API 5L Casing Steel Pipes and prevent the wellbore from collapsing, as well as to allow drilling mud to circulate for easier production.
Steel grades of oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc.Casing end processing form: short round thread,API 5L Casing Steel Pipes long round thread, partial trapezoidal thread, special buckle.For oil well drilling, it is mainly used to support the well wall during drilling and after completion, so as to ensure the drilling process and the normal operation of the whole well after completion.
The important position of oil pipeline
Oil industry is a large use of oil pipeline industry, oil pipeline in the oil industry occupies a very important position:
1, oil pipeline consumption is large, spend more money, save expenses, reduce the potential of great cost.Oil well pipe consumption can be estimated according to the annual drilling footage.According to the specific situation in China, in general, API 5L Casing Steel Pipes 62kg of well pipe is needed for each 1m drilled, including 48kg of casing and 10kg of tubing.Drill pipe 3kg, drill collar 0.5kg;
2. The mechanics and environmental behavior of petroleum pipelines have an important influence on the adoption of advanced technology andAPI 5L Casing Steel Pipes increase production and efficiency in the petroleum industry;
3, the oil pipeline failure loss is huge, its safety, reliability and service life of the petroleum industry is of great importance.
