高升油田莲花稠油油藏剩余油分布规律研究

Distribution of residual oil in Lianhua heavy oil reservoir of Gaosheng oilfield

针对辽河油区高升油田莲花稠油油藏地质及开发特点,定性地分析了稠油油藏蒸汽吞吐开发剩余油形成机制和规律。以钻井取心、化验分析、试油、试采及测井资料为基础,采用数理统计、神经网络分析等多学科有机结合的方法,指出了剩余油在纵向上和平面上的定量分布规律及蒸汽吞吐井水淹波及范围。

In accordance with the geological and development features of Lianhua heavy oil reservoir in Gaosheng oilfield of Liaohe oil province , the mechanism and distribution of residual oil of cyclic steam stimulation are qualitatively analyzed. Based on drilling, coring, assay, formation testing, production test, and logging data, vertical and horizontal distribution of residual oil and water - flooded zone of cyclic steam stimulation are pointed out through combination of multidiscipline such as mathematical statistics and neural network analysis, etc. This provides basis for improving measures and adjustment plan.
