摘　　要：南堡油田1号构造人工岛由于长期开采,造成储层压力亏损,钻井过程中经常出现失返性漏失,堵漏时间长、漏失量大.室内实验采用HD-Ⅱ型堵漏仪,采用不锈钢的缝板模拟宽度为1.0～10.0 mm等不同规格的裂缝,分别对2种主要片状锲入剂NTS-S（酸溶性堵漏剂）和NTS-M（超强堵漏剂）进行了承压堵漏实验,并优选出一套高效承压堵漏配方.该堵漏剂配方以大颗粒状高承压堵漏剂为架桥剂、片状堵漏剂NTS-M复配NTS-S为多层叠加锲入剂、纤维类材料SQD-98为桥接剂,并配合不同级配填充类堵漏剂,室内评价其承压值可达7 MPa.南堡13-1170井通过应用该套堵漏技术,承压堵漏一次成功,并确保了该井下套管、固井顺利完成,固井质量合格.The Structure No.1 of Nanpu, an artificial island, has found formation pressure depletion because of long period of production. Mud losses have been a major problem for safe and economic drilling operation. A high performance LCM slurry, which is aimed at controlling mud losses under pressure, is recently developed. This LCM slurry uses large bridging particles, flake LCM NTS-M and NTS-S and fiber LCM SQD-98 as well as sized packing LCM in a certain mass ratio, can hold pressures up to 7 MPa in laboratory test. Mud losses in well Nanpu13-1170 was completely controlled at the first use of this LCM slurry, and subsequent jobs such as casing running, cementing were all successful.
