地震属性分析技术在波斯湾盆地中部S区块储层预测中的应用

Application of seismic attributes analytic technique to reservoir prediction in some block of central part of Persian Gulf basin

本文以波斯湾盆地中部S区块为例,运用地震属性分析技术,结合地质、测井及地震等资料,在层位精细标定和构造精细解释的基础上,应用正演模拟方法从中优选出能够反映该区储层物性及含气性较敏感的瞬时振幅、瞬时频率、瞬时相位等3种属性,并依据这3种地震属性的分布特征,对储层的平面分布特征进行了描述。在此基础上结合测井资料,将该区储层分为四类,其中:M井区综合评价为一类储层;M井区西北综合评价为二类储层;H井区综合评价为三类储层;F井区以南综合评价为四类储层。可见地震属性分析技术可为该区隐蔽油气藏的勘探与开发提供可靠的依据。

Taking some block of central part of Persian Gulf basin as an example, using seismic attributes analytic technique and in combination with geologic, logging and seismic data, the paper, on the basis of fine horizons calibration and structural interpretation, carried out description of planar distributing feature of reservoir by using forward simulation and optimizing three attributes: instantaneous amplitude, frequency and phase that can reflect the physical nature of reservoir and is sensitive to gas-beari...
