四川盆地井漏处理技术实践与研究

Practice and research of well leakage treatment technology in Sichuan Basin

针对四川盆地钻井漏失频率高、处理措施效果不理想的现状,对四川地区的地形进行了分析和评价,分析钻井、固完井作业发生井漏的原因及特点。通过钻井、固完井施工过程中,川西马蓬15-1HF井、新22-1H井典型井漏及处理情况;川东HF203井、元坝29井、元坝102-侧1井、元坝21井典型井漏及处理情况;固完井马蓬26井、马蓬46井、马蓬11井、川孝489井、新沙23-18HF井、HF203井典型井漏及处理情况进行综合案例分析,总结出了四川地区井漏的处理方法。

In view of the present situation of high drilling loss frequency and the effect of treatment measures in Sichuan basin, the topography of Sichuan area is analyzed and evaluated,and the causes and characteristics of the leakage of drilling and cementing well completion operation are analyzed and evaluated. By drilling,well cementing and completion in the construction process, Sichuan mapoon 15-1HF wells,new wells 22-1H typical wells leakage and treatment;Sichuan HF203 and Guangyuan 29 wells, Guangyuan 102- side 1 and Guangyuan 21 wells typical wells leakage and treatment;comprehensive case of solid completion mapoon 26 wells,mapoon 46 wells 11, mapoon Chuanxiao 489 wells, wells, wells HF203, 23-18HF shinsa typical wells leakage and treatment situation analysis,summed up the processing method of leakage in Sichuan area.
