摘要：

当地层孔隙发育时,其层速度必然降低.故可据低速异常预测孔隙发育带;当地层中富含油气而不是水时,也会使层速度降低.如选择一套岩性较稳定、孔隙度变化较小的储层,便可根据其速度参数的变化来检测油气是否存在.

Abstract:

The use of Differential Interformational Velocity Analysis (DIVA) in hydrocarbon seismic indication in Northern Tarim Basin is discussed in this paper, and the procedures of the DIVA mapping and interpretation have been improved so that the procedures may be applied to indicate hydrocarbon in deeper (>4500m) strata. The results of the comparation and analysis of Shacan-2 and Sha-7 wells suggested that the hydrocarbon potential of the formations is closely related to the abnormal zones of differential interformational velocity. The abnormal amplitudes fit well with the amounts of hydrocarbon in corresponding formation sections. This shows that the DIVA procedure could not only be used to detect formation porosity, but also could be used to detect subsurface hydrocarbon even in deeper strata.
