摘要

摘要: 安探4X井是中石油华北油田公司为了勘探杨税务潜山含油气性所部署的一口风险探井，完钻井深为6 455 m。该井四开以后地层岩性主要为灰岩、泥岩，井底最高温度在210~217℃之间，超高温对钻井液处理剂的抗温性能提出了极高的要求。室内在现场浆的基础上，通过优选的4种关键处理剂对体系进行优化，构建出抗温200℃和220℃的低固相钻井液配方。现场钻井液维护过程中，根据井下温度环境，按照阶梯序列维护补充钻井液体系，最大程度地提升钻井液的性价比，在整个钻进过程中钻井液性能稳定，体现了良好的悬浮携砂性能，保障了四开超高温井段的顺利钻进。

Abstract: Well Antan-4X is a prospecting well for exploring the oil/gas reserves in the Yangshuiwu buried hill area in Huabei Oilfield. The depth of this well, 6455 m, has set a new record of well depth in Huabei Oilfield. The fourth interval of the well penetrated formations mainly with limestone and mudstone, and the down-hole temperatures are between 210-217℃, which poses rigorous requirement on the high temperature resistance of drilling fluid. Laboratory studies on the mud samples taken from well site have been conducted, and based on the studies 4 key mud additives have been selected to optimize the mud formulation, a low solids drilling fluid with temperature resistance up to 200-220℃. In field operations, the drilling fluid was maintained at its best state in accordance with bottom hole temperature, thereby to maximize the cost performance of the drilling fluid. During the entire drilling operations, the drilling fluid showed stable properties and good cuttings carrying performance, ensuring the safe drilling operations in the ultra-high temperature fourth interval.
