1 mm) of 3000~5300 m in which major hole stability problems faced is as follows: The hard brittle mudstones in the upper formation of Jura-Triassic and Carboniferous and the basalts in Permian is prone to strip and drop when drilling and sloughing and severe hole enlargement frequently occurred.
在这一井段面临的井眼稳定问题主要是:①侏罗系—三叠系、石炭系上部硬脆性泥岩及二叠系玄武岩地层易剥落和掉块、坍塌,扩径严重;②需要解决裸眼段多个地层压力系统共存和地层岩性差异较大的漏失问题,目前承压堵漏工艺技术还不过关;③巨厚盐膏层的塑性变形极易导致发生缩径卡钻,由于含盐膏泥页岩中的盐溶解及泥页岩的水化分散作用易造成井壁的不稳定性。
