摘要
自20世纪20年代以来,为解决钻井过程中遇到的各种复杂问题,在钻井液体系优化和新材料研发的基础上,对油基钻井液技术进行不断完善和改进,目前已形成包括抗高温、低固相、无土相、可逆乳化及恒流变等多种高性能油基钻井液体系和技术,并得到广泛应用。近年来,随着陆上易开采油气资源逐渐枯竭,世界范围内油气勘探开发逐步向页岩气、超深层、超深水等非常规油气、复杂油气资源迈进,对钻井液性能要求越发严苛。在水基钻井液无法满足要求的情况下,油基钻井液因固有的抗温性、页岩抑制性、水合物抑制性、润滑性和储层保护性等优势已逐渐成为钻探高温深井、大斜度定向井、页岩气水平井、海洋深水等各种复杂地层的主体钻井液技术,不仅给油基钻井液的发展带来了机会,也使油基钻井液面临前所未有的挑战。梳理并阐述油基钻井液的发展历程和目前技术现状、难点以及未来发展趋势;提出研发适合油基钻井液的“固壁剂”、油基钻井液配套的系列防漏堵漏材料、Gemini型油溶性聚合物等具特殊分子结构的絮凝剂、油基钻井液携屑剂、抗极高温度的乳化剂等,并开展生物质合成基液和绿色油基钻井液处理剂应用研究,以及采取光催化和微生物协同降解原理的废弃油基钻井液无害化处理研究。
Since the 1920s,in order to solve various complex problems encountered in the drilling process,the oil-based drilling fluid technology has been continuously improved based on the optimization of the drilling fluid system,as well as the research and development of new materials.At present,a variety of high-performance oil-based drilling fluid systems and technologies have been formed and widely utilized,including high-temperature resistance,low solid phase,no-soil phase,reversible emulsification and constant rheology.In recent years,with the gradual depletion of onshore oil and gas resources that are easy to exploit,oil and gas exploration and development around the world are gradually approaching unconventional and complex resources,such as shale gas,ultra-deep water.Hence,the requirements for drilling fluid performance are becoming more and more stringent.When water-based drilling fluid cannot meet the criteria,oil-based drilling fluid has gradually become the central drilling fluid technology for drilling high-temperature deep wells,highly deviated directional wells,shale gas horizontal wells,offshore deep-water and other complex formations due to its inherent advantages of temperature resistance,shale inhibition,hydrate inhibition,lubrication and reservoir protection,which not only brings opportunities for the development of oil-based drilling fluid,but also makes oil-based drilling fluid face unprecedented challenges.This paper reviews the development history,current technical status and difficulties,and future development trends of oil-based drilling fluid.The"wellbore strengthener"for oil-based drilling fluids,a series of leakage and plugging materials tailored for oil-based drilling fluids,flocculants with unique molecular structures such as Gemini-type oil-soluble polymers,debris-carrying agents for oil-based drilling fluids,and emulsifiers resistant to extremely high temperatures were proposed.The application of biomass-synthesized base fluids and environmentally friendly oil-based drilling fluid treatme
