摘要
对钻探堵漏技术的现状进行了分析。介绍了近期针对地质钻探堵漏开展的高强度快失水堵漏、高强度化学触变堵漏、溶胀型随钻堵漏材料以及成膜钻井液技术阶段科研成果。提出了加强漏失层特性判断与堵漏方法的关联性,广谱型堵漏技术,复合堵漏材料和堵漏技术集成化,高效随钻防漏材料和防漏冲洗液体系,膨胀管封堵技术研究等地质钻探堵漏技术的重点研究方向。
With the brief discussion on the status of lost circulation control, the paper introduced the recent scientific re-search achievements in view of the high-strength fast dehydration plugging, the high-strength chemical thixotropic materials plugging and the swelling plugging materials, as well as the film-forming drilling fluid technology. The paper also presents that the key research directions in the relevance of loss zone characteristics judgment and plugging measures; broad spec- trum plugging technology ; integration of composite plugging materials and leak-proof technology ; high-efficient materials for loss circulation control while drilling and leak-proof washing fluid system; and expansion tubular sealing technology.
