摘要
王府地区目前尚处于勘探阶段,已经发现天然气的储集。为研究该区域储层建筑结构,以城深7井作为标准井制作岩心相,分析取芯井岩相类型;对比研究区内所有探井的测井曲线,分析登娄库组各部分的沉积相类型及微相特征;计算登娄库组不同砂组的砂地比,分析水进水退趋势;通过单井校正和地震剖面上对下切谷的识别绘制砂组的沉积相平面图,描述沉积相展布和砂体展布情况。结果表明:登娄库组主要沉积相类型为辫状河三角洲沉积,分为辫状河道沉积微相、越岸沉积微相、水下分流河道微相和水下分流河道间微相四个沉积微相类型。登娄库组地层在沉积时期经历了一次水进水退旋回,最大湖泛面为d22时期,沉积期物源有北东和南西两个方向。王府断陷沉积受沉积环境和盆地演化影响。该研究为气藏开发提供了基础资料。
This paper is an effort to investigate the reservoir structure observed in Wangfu region with proven natural gas reserve at the stage of exploration. The specific investigation is performed by making core phase using the well cs7 as the standard and analyzing the facies; comparing logging curves between different exploratory wells to define the characters of every sedimentary facie and sedimentary microfacies;calculating the data in different sand groups by relating depositional cycle closely to the data of sand content; and thereby describing the distribution sedimentary facies and sand body using two main ways,such as single well correction and the incised valley finding on the seismic section. The results show that Denglouku formation is mainly marked by the types of sedimentary facies,identified as braided river delta deposit consisting of braided river sedimentary microfacies,shore sedimentary microfacies,underwater distributary channe,and underwater interchannel; in the sedimentary period,the formation experienced a water inlet annealing cycle,accompanied by and the maximum flooding surface of d22; and fault subsidence and deposition occurring in Wangfu region are subjected to the influence of the sedimentary environment and the basin evolution process. This study may provide basic data for further research into the gas reservoir.
