以发现并圈定通常存在于油气储中的平的流体和天然气界面为基础的勘探可能改进勘探效果,特别是对于小幅度构造和地层圈闭更是如此。流体界面的反射能力在最“亮”的(R=0.4)硫松砂岩中的浅层气液界面至最弱的(R=0.01)深层碳酸岩油水界面间变化(该处的反射能力可能受密度差的控制)。在倾斜岩性反射面背景中认出与地震构造等高线相一致的界面限制的、弱的平反射面,可以提供比较肯定的油气储标志,以及某些油储特性的资料如储层厚度等。识别能力取
Exploration based on the discovery and delineation of a flat fluid and gas interface commonly found in oil and gas reservoirs may improve exploration performance, especially for small-scale tectonics and formation traps. The reflectivity of the fluid interface changes between the shallow gas-liquid interface in the brightest (R = 0.4) fluvial sands and the weakest (R = 0.01) deep carbonate oil-water interface where the reflectivity may be affected by Density difference control). Recognizing interface-constrained, weakly flat reflectors consistent with seismic tectonic contours in the background of sloped lithologic reflections can provide more positive oil and gas reservoir indications, as well as information on some oil reservoir properties such as reservoir thickness Wait.
