摘要
辽河油区青龙台油田龙10块Es31为近源扇三角洲沉积,沉积微相变化快、砂体展布复杂、储集层非均质性较强,用确定性地质模型不能很好地反映储集层的"空洞效应"。为了较好地表征龙10块储集层的"空洞效应"及其物性的不连续性,应用密井网条件下的"硬数据"和地质家的经验,综合测井、录井及动态监测资料建立沉积微相的一维井模型,采用确定性建模方法建立沉积微相模型,在该模型控制下,应用序贯高斯随机模拟方法建立储集层及其相关参数分布的随机模型。实践表明,建立的模型能够很好地表征砂体展布及储集层参数的非均质性。
The environment of Es3^1 in Block Long 10 of Liaohe Oilfield is a fan delta near the source, the sand-body distribution is very complicated and the reservoirs have strong heterogeneity. To better characterize the discontinuity of the reservoir physical properties, micro-facies modeling is built in a deterministic way with the ＂hard data＂ of closely spaced wells and geologist＇s experience. Under the micro-facies modeling, the reservoirs and their parameter distribution are predicted by Sequential Gaussian Simulation. The accuracy and practicability of the method in the prediction are verified by application.
