摘要
青海油田柴达木盆地涩北气田是由多个层状水藏和气藏叠加而成 ,多年来其特有的地质特点给钻探工作带来了很大难度 ,多次发生井漏、井喷、卡钻等事故。文中对涩北气田的地质构造、储层特性及气藏特征进行分析 ,总结钻井施工经验和新技术应用 ,介绍涩北气田的钻井井控、钻井液技术及施工措施 ,对涩北气田的钻探工作有一定的指导意义。
The geologic structure of Sebai gas field,Qinghai Chaidamu Basin is much complicated.The gas reservoir which is shallow and the well is deeper.The reservoir is non-diagenetic formation with high shale content.The gas field is composed of many banded water reservoir stacking gas reservoir,which has own special geologic characteristics that always brings many problems in drilling like lost circulation,blowout,sticking etc..The paper analyses the geologic structure and reservoir characteristics of Sebai gas field,summarizes the drilling experiences and the applications of new technique in resent years,introduces the well control,drilling fluid technique and operation measures in Sebei Gas Field.
