埕海油田地质条件复杂,沉积类型多,储层纵横向变化快,油藏类型复杂多样,储层精细预测难度大。针对储层预测的难题,使用多种技术手段来解决储层研究的多解性,如应用地震属性分析技术圈定有利储层范围,利用频谱成像技术提高储层空间横向识别能力,利用测井约束地震反演技术提高储层垂向分辨率,利用河道边缘检测技术,描述末期河道,通过综合应用各种技术的优点,从而实现对单砂体由点到面再到体的识别与追踪。
The geological conditions of Qionghai Oilfield are complex, the sedimentary types are multifar, the vertical and horizontal changes of reservoirs are fast, the types of reservoirs are complex and diverse, and the precision of reservoir prediction is very difficult. In view of the difficulty of reservoir prediction, a variety of techniques are used to solve the multi-solution of reservoir research. For example, the application of seismic attribute analysis to delineate the favorable reservoir range, the use of spectral imaging technology to improve the lateral recognition of reservoir space, Seismic inversion technique can improve vertical resolution of reservoirs, and use the edge detection technology of the river to describe the terminal channel. By combining the advantages of various techniques, the single sand body can be identified and tracked from point to plane and then to the body.
