八面河地区河道砂体描述方法与应用

Channel Sand Body Description Method and its Application in Bamianhe Area

根据八面河地区的沉积特点,分析河道砂体的响应特征,引进先进的勘探技术与方法对河道砂体进行精细描述,预测河道砂体展布,寻找有利圈闭,形成一套适用于八面河地区的河道砂体描述方法,发现有利勘探目标区2个,其中面138北部地区含油河道已被钻井证实,新增探明石油地质储量176万吨。

Based on the sedimentary characteristics and analysis results of seismic response feature of channel sand bodies in Bamianhe Area, fine description of channel sand bodies has been conducted by using advanced hydrocarbon exploration technique and method in order to predict distribution of these sand bodies and find favorable traps. A suit of channel sand body description methods for the area has been established. What＇s more, two favorable exploration targets have been discovered, of which oil--bearing channel sand body in the north of Mian--138 Block has been confirmed by well drilling. The proven geological reserve is increased by 176＊10^4t.
