Leakage analysis and plugging technology for Permian igneous rock in Shunbei Oil and Gas Field
-
摘要: 顺北油气田二叠系火成岩地层破碎、裂缝发育、压力敏感、埋深超过4445 m、厚度大于548 m,钻进过程中漏失严重。自2013年勘探开发以来,应用过水泥、化学固结、高失水、化学凝胶、桥接堵漏和堵漏浆钻进等技术。通过分析二叠系火成岩地层特性,明确了漏失原因;通过分析堵漏技术,结合前期应用情况,明确了不同漏失适用的堵漏技术,最终确定了“中小漏失采用桥接堵漏、多点漏失采用全井堵漏浆钻进、大漏采用化学固结或高失水堵漏专堵”的4种堵漏技术。通过推广应用,顺北油气田1号断裂带和5号断裂带二叠系火成岩地层漏失量和堵漏时间得到明显控制,漏失量减少87.2%,堵漏时间缩短92.9%,取得了显著效果。Abstract: The Permian igneous strata in Shunbei Oil and Gas Field has the following characteristics: fragmentation, fracture development, pressure sensitivity, burial depth of more than 4445m, thickness of more than 548mm, and serious leakage during drilling. Technologies such as cement, chemical consolidation, high filtration, chemical gel, bridge plugging and plugging slurry drilling have been applied since the exploration and development of the field in 2013. The leakage causes are defined by analyzing the characteristics of Permian igneous rock strata. The plugging technology applicable to different leakage is determined through the evaluation of the applied plugging technology with the application results. Finally four plugging technologies for different leakage layers are determined with bridge plugging for small and medium fractures, plugging slurry drilling for multi fracture leakage layers, and chemical consolidation or high filtration plugging for large fractures. Through popularization and application, the plugging time and leakage amount of Permian igneous rock formation in No. 1 fault zone and No.5 fault zone of Shunbei Oil and Gas Field have been significantly controlled with the leakage amount reduced by 87.2%, and the plugging time cut by 92.9%.
