甲油田X油层组精细地质建模研究及应用

Research and Application of Fine Geologic Modelingof X Formation of Oilfield A

甲油田X油层组为一既受构造背景控制又受岩性(物性)影响的岩性构造层状油藏,对其构造特征及含油富集规律认识的不足严重制约了区内勘探开发进度。采用地震体、沉积相约束,并结合测井二次解释成果,建立了研究区X油层组精细油砂体模型,并通过其对各储层参数进行约束和模拟,精细刻画了油气富集区,为下一步的开发调整和稳产提供地质依据。

The X formation of Oilfield A was lithological-tectonic reservoir controlled by both structural background and lithologic property(physical property).The structural characteristics of the reservoir and oil enrichment regularity were insufficiently recognized and the progress of oil exploration and development in the area were severely restrained.The oil sand body model is determined for fine reservoir interpretation by using secondary interpretation results of logging and seismic inversion data volume,then,the reservoir parameters are constrained and fine simulated by using the model.So the oil enriched region is fine characterized,and it provides geological basis for the next development and stable production of the oilfield.
