摘要: 利用地震相分析和测井相分析来综合研究和解释沉积相是岩性油气藏有利区带优选和储层预测最有效的技术手段。针对鄂尔多斯盆地D16井区储层多层系、物性特征复杂和储层层薄等特点,采取了相控储层预测思路。也就是先进行测井相分析和地震相分析,然后,应用测井微相解释结果标定地震相,建立了储层的地震响应模式,并通过模式识别方法实现砂体的横向预测。优选出强振幅地震相和透镜状地震相是研究区最主要的有利地震相,并预测其在研究区的空间展布规律。

Abstract: Using seismic facies analysis and log facies analysis to do comprehensive research and interpretation of sedimentary facies is the most effective approach for optimum selection ideal area and reservoirs prediction of lithologic reservoir. Reservoirs in D16 Well Block are thin and they are characterized by multiple strata and complex physical properties. In view of this, facies-controlled idea of the prediction is adopted, i.e. analyzing the seismic facies and log facies first, and then calibrating the result of the seismic facies by log micro-facies. Based upon this, seismic response patterns of reservoirs are built. Finally, the spatial distribution of reservoirs could be predicted. It is found that strong amplitude seismic facies and lentoid seismic facies are the most potential seismic facies in the area, and their distributing regulations are predicted

Key words: lithologic hydrocarbon reservoir, seismic facies, facies analysis, reservoir prediction
