| 摘 要： | 渤中13—1油田古近系沙河街组沙一段顶部发育一套薄层生屑云岩油气藏。由于该储层具有厚度薄、埋藏深、横向变化快、预测难度大等特点，给油田钻探部署带来了极大的困难。运用类比分析及相控储层预测技术，对薄层生屑云岩的分布特征和成因进行了系统分析，并预测生屑云岩储层有利区带，优化钻前井位部署。经钻探证实均获良好效果，钻探成功率达100％，经投产测试均获高产油气流，为相似油藏的开发部署提供了良好的借鉴和指导作用。

| Abstract: | At the top of Shahejie section developed a thin bioclastic dolomite reservoir in BZ13 - 10ilfield. Due to the control of the ancient sedimentary environment, the reservoir has followed characteristics such as thin layer, large buried depth, and lateral variation, so it＇ s difficult to be predicted and bring great difficulties to drilling deployment. To solve these problems, analogous analysis and reservoir prediction was applied, comprehensive analysis of the reservoir characteristics and control factors of thin bioclastic dolomites was carried on, favorable area of bioclastic dolomite was forecasted and well location optimization before drilling was done. The results showed 100 % drilling success rate, high-yield oil and gas flow by testing was obtained, providing a good guide for similar reservoir study. |
