本文提出一种地震声速与测井声速对比勘探石油的设想。此法拟利用垂直地面方向的纵波声速,即纵向地震声速与测井纵波声速。位于潜水面以下的诸地层中,其纵向地震声速明显地小于测井纵波声速的地层应是油气层,而具有相同纵向地震声速的连续延伸区域应属于同一圈闭,其中贮有油气。与贮有油气的圈闭相邻的其他圈闭,如果具有相同的纵向地震声速,也可能贮有油气。在原理上,以上规律对砂层和灰层均能适用。
This paper presents a scenario of seismic sound velocity and logging sound contrast exploration of oil. This method proposes to use the longitudinal wave velocity perpendicular to the ground, that is, longitudinal seismic sound velocity and the sound velocity of the LWP. Among the strata below the surface of the submerged surface, the strata whose longitudinal seismic sound speed is obviously less than the sound velocity of the longitudinal compressional wave of the well logging should be a hydrocarbon layer, while the continuous extension region with the same longitudinal seismic sound velocity should belong to the same trap, in which oil and gas are stored. Other traps adjacent to traps containing oil and gas may also store hydrocarbons if they have the same longitudinal seismic sound velocity. In principle, the above rules apply to the sand and ash layers.
