近几年来塔河油田在飞速发展,年产量在逐年上升,是西部地区具有重要贡献的原油开发之地之一。塔河油田在油田上部钻井时容易产生缩径阻卡的现象,因为上部的地层比较疏松,具有较好的可钻性;在油井下部钻井时由于地层掉块剥落、严重坍塌,经常会出现复杂的井下事故,存在的溶洞或裂缝会导致钻井液漏失。所以,塔河油田采用了一系列的先进工艺钻井技术,并且不断地提高改善技术,尽可能地降低成本,提高经济效益。
In recent years, the rapid development of Tahe Oilfield, annual output increased year by year, is one of the western regions have an important contribution to the development of crude oil. Tahe oilfield prone to drilling in the upper oil wells reduce the diameter of the blocking phenomenon, because the upper strata relatively loose, with good drillability; drilling in the lower reaches of the well as the formation of flaking off, serious collapse, often complicated Of underground accidents, the existence of caves or cracks can lead to drilling fluid loss. Therefore, Tahe Oilfield adopted a series of advanced technology drilling technology, and constantly improve the technology to reduce costs and improve economic efficiency.
