页岩气固井技术对于油田油井寿命和资源保护起至关重要的作用。是通过在井壁和套管中的环空注入水泥浆实际保护油井为目标的工程水平井固井技术。随着钻井技术的进一步提高,为页岩气固井工程提出了新的要求,能够促进页岩气水平井固井的更好发展。因此,在工程建设中,应及时开展页岩气水平井固井技术的工作及相关措施,避免由水平井固井技术所引起工程事故。
Shale gas cementing technology plays an important role in oil well life and resource conservation. Is a horizontal well cementing technology that aims to actually protect oil wells by injecting grout into the annulus in casing and casing. With the further improvement of drilling technology, new requirements for shale gas cementing projects are put forward, which can promote the better development of horizontal well cementing in shale gas. Therefore, in project construction, the work of shale gas horizontal well cementing technology and related measures should be carried out in time to avoid engineering accidents caused by horizontal well cementing technology.
