灰岩油藏，尤其是处于风化壳部位的灰岩油藏孔缝洞发育，钻井过程中钻井液漏失现象严重，会导致无法钻进或卡钻恶果。根据任平２井所在的储层特点和钻达３３４７～３３９０ｍ井漏段，采用有机化学堵剂工艺技术较圆满地解决了这个问题。介绍了 ＴＣ—９３８化学剂及凝胶的性能，堵漏原理及在该井的现场应用，通过堵漏工艺技术分析看出应用化学剂堵漏工艺技术在任平２井的水平段堵漏施工十分成功，并取得了理想的效益。认为这是促进整体钻井工艺技术水平的一项新技术，值得推广。
Limestone reservoirs, especially those in limestone reservoirs with weathered crusts, are well developed. Drilling fluid loss during drilling is serious, leading to inability to drill or drill. According to the reservoir characteristics of Renping-2 well and drilling up to 3347 ~ 3390m well-drain section, the organic chemical plugging process technology is a more satisfactory solution to this problem. Introduced the TC-938 chemical and gel properties, plugging principle and field applications in the well, through the plugging process technology analysis shows that the application of chemical plugging technology in Ren Ping 2 wells horizontal plugging construction is very Success, and achieved the desired benefits. This is considered as a new technology to promote the overall drilling technology and is worth promoting.
