在一定地质条件下,地震描述技术能有效地区分储层与围岩,从而更直观地描述储层(或油层)的发育情况。应用于油气地质储量计算,能有效地提高储量计算的精度。新滩油田馆陶组油层发育受构造、岩性双重因素控制,油层发育横向连通性差,变化快,单层厚度小。常规方法用钻井资料、构造等值线圈定含油面积,所计算的石油地质储量误差较大,应用地震描述技术后取得了较好的效果。

Using seismic description technology can effectively distinguish the reservoir layer and the round layer on the certain geology condition,and we can describe the shape of reservoir layer(oil layer) visually. Using it to compute reserves, the accuracy of calculation can be increased.In Guantao FM of Xintan oil field, the oil layer is controled by structure and lithology. Horizontally it connecting the universality badly, change quickly, thickness of single layer is small. With the normal method of using the well data and structure bathymetric to define oil bearing area, quantity of geological reserves is not accurate. After using seismic description technology, we obtain a good result.
