油井套管补贴大修技术

Casing patch workover technology

针对辽河油区目前套管损坏井不断增多的现状,开展了套管补贴大修技术研究。该项技术不仅适用于中浅层的套损井,也适用于中深层的套损井。现场试验表明:套管补贴工艺技术是一项成本低、简便适用的套损井修复工艺技术;对油田开发进入中后期,增产节资,将起到积极有效的作用。

In accordance with the current situation of increasing number of casing failure wells in Liaohe oil province, study on casing patch workover is carried out. This technology can be used not only in mid-shallow casing failure wells, but also in mid-deep casing failure wells. Field test shows that, casing patch technology is a low cost and easy to operate method for workover in casing failure wells, which will be of great help for increasing production and saving cost in mid-late period of oilfield development.
