| 中文摘要:井漏的发生不仅给钻井工程带来损失,也为油气资源的勘探开发带来极大困难。顺北地区二叠系火成岩发育，地层破裂，钻井时井下复杂主要表现为漏失。目前，该区块二叠系井漏现象频发，导致坍塌掉块，造成该区块井下复杂高发，给施工进度带来非常不利的影响。针对此问题，开展了顺北地区二叠系随钻堵漏技术研究，结合顺北1-1、1-5和1-6井的钻井实践以及二叠系地层特点，分析了该区块的二叠系钻进难点，总结了随钻堵漏技术具体的施工措施。为了应对地层可能出现较大漏失的情况，优选出了用于堵1、3和5 mm缝板的堵漏配方。 |

| Abstract:Well leakage brings not only losses to drilling engineering, but also great difficulties to the exploration development of oil gas resources. Permian igneous rock developed in the northern part of Shunbei area with formation fractures, leakage in drilling process is the main complex downhole situation. At present, Permian leakage happens frequently, which causes collapsing and block falling and has adverse effects on construction progress. To solve this problem, the research on plugging while drilling technology for Permian in Shunbei area is carried out. Combined with the drilling practice of wells SHB 1-1, SHB 1-5 and SHB 1-6 and considering Permian strata characteristics, this paper analyzes the drilling difficulties of Permian in this block and summarizes the concrete construction methods of plugging while drilling technology. In order to cope with the possible large leakage, plugging formulas are optimized for the boards with seams of 1, 3 and 5mm respectively. |
