摘要

因地质、工程、环境及人为因素,深井超深井极易发生钻井液漏失,给钻井作业带来危害,但目前关于深井超深井堵漏技术的研究成果较为分散,缺少系统性。为此,通过文献调研,分析了深井超深井钻井液漏失原因,总结了深井超深井堵漏工艺技术及不同种类堵漏材料的研究进展,分析了深井超深井堵漏技术存在的问题,并对未来发展进行了展望。研究表明:将地质、工程、材料和智能堵漏技术有机结合,改进堵漏材料的配方及抗温、抗盐、抗压性能,优化注入方式、注入压力、注入剂量等工艺参数,充分考虑井筒-漏点-地层之间的流动耦合,综合利用储层堵漏与解堵技术,使用人工智能技术对以往堵漏案例进行深度学习并对新井的堵漏方案进行智能决策,可显著提高深井超深井堵漏效果。该研究可为深井超深井堵漏技术的应用提供参考和指导。

Abstract

Deep and ultra-deep wells are highly prone to drilling-fluid loss because of geological,engineering,environmental,and human factors,which can seriously endanger drilling operations.However,current research achievements on lost-circulation control in deep and ultra-deep wells are relatively scattered and lack systematic synthesis.Through a literature review,this paper analyzes the causes of drilling-fluid loss in deep and ultra-deep wells,summarizes progress in lost-circulation control technologies and in different categories of plugging materials,and discusses existing problems and future development directions.The study indicates that significant improvement in lost-circulation control for deep and ultra-deep wells can be achieved by organically integrating geology,engineering,materials,and intelligent plugging technologies;improving the formulations and the temperature resistance,salt resistance,and pressure-bearing capacity of plugging materials.Besides,the following measures can also help,such as optimizing process parameters such as injection mode,injection pressure,and injection volumefully considering the coupled flow among the wellbore,loss zone,and formation,comprehensively utilizing reservoir plugging and plug-removal technologies,and applying artificial intelligence to perform deep learning on previous lost-circulation cases and to make intelligent decisions for plugging programs in new wells.This study provides a reference and guidance for the application of lost-circulation control technologies in deep and ultra-deep wells.

Key words： deep and ultra-deep wells; drilling fluid; lost circulation; plugging
