摘要
寻找和开发剩余油气藏是提高采收率的关键.以往主要是通过测井、试井资料建立中高层渗透砂岩油藏的井间剩余油分布模型,并采用数学分析方法建立井间剩余油的预测模型.本文介绍了基于高分辨率地震和精细测井分析建立剩余油模型并结合数模分析的剩余油分析技术.利用该技术对辽河油田某断块进行了实际剩余油气分析,在开发方案设计和提高采收率方面取得了明显的效果.
Seeking and development of residual oil/gas are the keys to enhance the recovery ratio. Traditionally, the cross-well distribution model of residual oil/gas in the high-level seepage sandstone is built with the logging and testing well data and then the prediction model is established using the mathematical analysis method. In this paper we present a new method with the data of high resolution seismic and fine well logging combing with the numerical model analysis. The new method is introduced into the analysis of a fault block in Liaohe oilfield and this application shows that it is effective for the design of developing plan and the enhancement of the recovery ratio.
