| 摘 要： | 临清坳陷某区块缺少岩心、薄片、录井及常规测井资料。为了研究其目的层山西组沉积相对储层的控制作用,指导非常规天然气的高效开发。通过利用较少的录井岩性统计资料,结合地震物探方法,分析地震剖面特征、优选地震均方根振幅及相对波阻抗属性,确定该区目的层沉积相。通过上述地震属性研究的物探方法,确定山西组储层为河控浅水三角洲相和碳酸盐台地相,主要发育分流河道、分流间湾及局限台地沉积微相。其中三角洲相是主要的沉积相类型,分流河道是有效储层发育的主要微相类型。

| Abstract: | The core, thin section, logging and conventional logging data are lacked in a certain block of LinQing depression. In order to study its purpose layer in the control action of sedimentary facies of reservoir of shanxi formation, to guide the efficient development of unconventional gas.By using less logging lithology statistical data and combining seismic geophysical method, the characteristics of seismic profile, root-mean-square amplitude and relative wave impedance are analyzed, and the target sedimentary facies are determined. By this geophysical method through the above seismic attribute study, it can be got that the reservoir of shanxi formation contains fluvial-dominated shallow water delta facies and carbonate platform facies, with the main sedimentary microfacies of distributary channel, distributary bay and restricted platform. Delta facies is the main sedimentary facies type and distributary channel is the main microfacies type of effective reservoir development. |
