摘要:
桂融页1井位于广西喀斯特地貌带,地质条件复杂、邻井资料少,施工中面临诸如井漏风险高、地层易垮塌、防斜打直难度大、钻头磨损严重、机械钻速低等问题。为此,在井口位置确定时应用物探法规避溶洞或破碎带,采取井身结构优化、空气钻、主动控斜保证井身轨迹、优化高研磨性地层钻头、应用中长筒取心、钾胺聚合醇聚合物防塌钻井液体系等技术,顺利完成钻井施工,钻机台月比设计方案缩短10 d。并在石炭系鹿寨组发现良好的油气显示。
Abstract:
Guangxi’s karst landform belt contains well Guirongye 1,which has difficult geological circumstances and scant adjacent well data. During construction,it faces problems such as a high risk of lost circulation,easy formation collapse,difficulty preventing deviation and straightening,severe drill bit wear,low mechanical drilling rate,and so on. When the wellhead position is determined,the geophysical method is used to avoid karst caves or broken zones,and the drilling construction is completed successfully by employing technologies such as wellbore structure optimization,air drilling,active deviation control to ensure wellbore trajectory,optimization of highly abrasive formation drill bits,medium and long barrel coring,potassium amine polymerized alcohol polymerization prevention drilling fluid system,and so on,and then the drilling rig month is 10 days shorter than the design plan. The Carboniferous Luzhai Formation also has good oil and gas showing.
