摘要

苏里格气田主要产层下石盒子组盒8段储层属典型的辫状河沉积,针对苏里格气田北部多波多分量三维地震工区内钻井少的具体情况,在研究中将Stratimagic地震相分析技术、地震多属性分析技术及相对波阻抗分析技术相结合,以钻井资料及古地貌分析结果为基础,对本区沉积相进行了研究。研究结果表明整个工区属辫状河相沉积,发育辫状河河道及泛滥平原沉积微相,物源来自于工区的北部,工区内有近南北向的3条主河道,同时发育多条分支河道,其中西部主河道的发育规模最大且河流交汇现象明显。

Abstract

The reservoir in the eighth member of lower Shihezi Formation in Sulig Gas Field is typical braid river sedimentary system. Drilling wells in 3D multiwave multicomponent work area in northern Sulig Gas Field are little. Based on the well data and the analysis of the palaeogeomorphology, the sedimentary facies were studied with applying the analysis techniques of Stratimagic seismic facies, seismic multi - attribute and relative wave impedance. The result showed that the whole work area is braid river sedimentary system which develops braided channel and flood plain deposit microfacies, and that the provenance come from northern work area where there are three main channels in NS direction, and several distributary channels developed. The development of the western main channels is the biggest, and the western channels show obvious convergence.
