| 摘 要： | 多压力系统井段钻井中,常出现"又喷又漏"的复杂情况,一直是困扰安全钻井的一个重大技术难题.目前处理这类问题一般采用常规复合堵漏或水泥浆堵漏的方法,但存在着一次堵漏成功率低、效果差、深井或高密度下用水泥浆堵漏易闪凝等问题.为此,从水基热敏性重晶石成塞堵漏的作用机理进行分析,并在室内对其影响因素、配方、成塞条件、塞子强度等进行研究,形成了具有热敏性强、成塞快、强度高、塞子厚度可调、施工简便等特点的水基重晶石成塞堵漏技术.该技术在剑门1井和龙岗001-27井堵漏中应用均获得成功,较好地处理了"上喷下漏"或"下喷上漏"的复杂情况.

| Abstract: | Some complex situations including blowout and lost circulation may take place during drilling certain well section with multi pressure systems, which affects severely a safety drilling. So far, there are always two methods to overcome this problem, such as conventional compound plugging and slurry plugging. However, for these two methods, there are many disadvantages of low success ratio and poor effect in primary plugging, and flash condensation of slurry plugging easily occurring in some deep wells or cer... |
