Study on Mud Loss Control Technology for Sulige Gas Field
-
摘要: 苏里格气田普遍存在低压易漏层,不同程度地存在构造裂缝、微裂缝,并且具有一定的区域性。介绍了苏里格地区易漏地层地质特点。根据历年来苏里格地区堵漏的经验,对现场堵漏实例进行了分析研究,提出了几种针对不同地层、不同漏失机理的有效堵漏方法,望能对该区块同类井的堵漏施工起到一定的借鉴和帮助作用。Abstract: Structural fractures and micro fractures are highly regionally developed in the low pressure formations in Sulige gas field.This paper discusses the geological characteristics of the formations in the gas field in which mud losses are easy to occur.Case histories of mud loss control are studied based on the experiences gained through field practices.Several effective methods of mud loss control are presented in this paper, and are expected that they are of helpful in mud loss control in similar situations.
