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。
Under certain geological conditions, seismic description technology can effectively distinguish between reservoir and surrounding rock, so as to describe the development of reservoir (or reservoir) more intuitively. Applied to the calculation of oil and gas geological reserves, can effectively improve the accuracy of reserves calculation. The development of the Guantao Formation in Xintan Oilfield is controlled by the dual factors of structure and lithology. The lateral connectivity of the reservoir is poor, and the change is rapid with a small single layer thickness. Conventional methods use well data and construct contours to define the oil-bearing area. The errors in the calculated oil geological reserves are large, and good results have been obtained after using seismic description techniques.
