| 摘 要： | 针对川东北地区钻井漏失频率高、处理措施效果不理想的现状,运用数理统计方法对钻井漏失及其处理措施进行了分析、评价。在对川东北地区钻井漏失层进行统计的基础上,依据漏失发生频率、孔道类型、严重程度、漏失特点以及堵漏现状,将川东北地区漏失层分为4个层段,各个层段及其特点分别是:飞仙关组,堵漏难度最大;嘉陵江组,漏失频率最高;须家河组—自流井组,"高孔低破"喷漏同层;蓬莱镇组—沙溪庙组,已得到较好解决。对川东北地区目前应用的堵漏措施进行了归纳总结,并结合各井漏处理措施的封堵机理和现场堵漏效果,总结了11种漏失处理措施的优缺点和适用范围,指出了目前该地区堵漏存在的主要问题并提出了对策。

| Abstract: | For the problem of high frequency of circulation lost and unsatisfactory treatment measures in Northeast Sichuan Basin,statistical mathematics is used to analyze and evaluate the circulation lost and treatment measures.Based on the statistical results,the circulation lost formation in Northeast Sichuan Basin were divided into 4 groups according to the frequency of lost circulation,pore throat type,severity,lost circulation characteristics,and well plugging.Each group has their own characteristics.Well plugg... |
