摘　　要：从井身结构、造斜点选择、钻井液性能、堵漏方式和技术措施上进行了分析研究,提出了一套适合广安002号区块的综合治漏技术,给出了小漏(0～5m3/h)、中漏(5～30m3/h)和大漏(30m3/h～失返)的推荐堵漏方案。通过对广安002-H1-2、广安002-H9、广安002-X28等井现场应用的分析,发现该种综合治漏技术取得了明显的效果,减少了因井漏造成的垮塌、卡钻、形成新井眼等事故,缩短了钻井周期,降低了钻井成本。A set of comprehensive techniques to control lost circulation has been developed in Guang＇an- 002 block,by analyzing wellbore structure,hole deviation points,drilling liquid properties and ways and measures to control lost circulation,and different scenarios are recommended for small lost（0-5m3/h ）,middle lost （5-30m3/h） and large lost（3Om3/h-no return） respectively.The applications of these techniques in several wells, such as GA002-H1-2,GA002-H9 and GA002X28,have resulted in significant effects in controlling lost circulation,decreasing various accidents caused by lost circulation （e.g.collapse,drill tool sticking and new hole creation） ,reducing drilling time and saving drilling cost.
