摘要
王官屯油田沙河街组沙一段生物灰岩、沙三段以及孔店组火成岩目的层容易发生裂缝性和孔洞性漏失,严重影响了钻井速度。通过对发生井漏的原因进行分析,结合近5年的现场应用经验,并经过室内研究,提出对该区块的井漏需采取预防为主和有针对性的堵漏相结合的综合防漏堵漏方式,形成了防漏堵漏钻井液技术措施,为优质高效地完成王官屯油田钻井施工提供技术保障。
Mud losses were encountered in several formations such as the 1st member of the Shahejie formation（bioaccumulated limestone）,the 3rd member of the Shahejie formation and the Kongdian formation（igneous rock）,and characteristic of fracture and cavernous. Based on the analyses of the causes of mud losses,a set of mud loss control technology was presented and adopted in subsequent drilling operation.The analyses concluded that a complete set of mud loss circulation prevention and control method should be used. This paper is to provide technical support for quality and efficient drilling in Wangguantun oilfield.
