利用砂体叠加部署聪明井提高勘探开发效果

通过相应属性的叠加可提高油气勘探开发的分析效果，减少投资风险。在勘探中采用精细沉积微相分析技术，通过对勘探目标区各小层沉积微相分析，编制各层的砂体分布图，提取各层砂体中主力砂体，编制小层主力砂体的叠加图；通过对叠加图分析，确定优势储层分布区域，进行成藏风险评价，提高了布井效果。而在油田开发调整中，通过对各单层进行精细沉积微相分析，确定其平面分布特征，结合各成因砂体的控制和动用程度，确定成因砂体内的剩余油分布情况，进而确定剩余油富集砂体，并制作剩余油富集砂体叠加图，据此以成因砂体为单元部署高效聪明调整井，提高了油田的采收率和开发效果。

Smart Well Designing Based on the Superposed Graph to Decrease the Petroleum Exploration and Exploitation Risk

Taking usage of superposed graph can increase the petroleum exploration and exploitation effect and decrease the risk. In the petroleum exploration, through the detailed facies analysis, microfacies distribution of each layer can be mapped. When the framework reservoir sandstones are determined, superposed map of the them can be drawn and the location of good reservoir can be analyzed to drill exploration wells. While in the petroleum exploitation, through the detailed microfacies analyzing to determine the distribution of genetic sandstone, and combining with the development data, genetic sandbodies which are not well controled by production and water injection wells can be recognized. Superposing these genetic sandbodies may tell us the location for drilling smart wells which may produce more oil and less water.
