| 摘 要： | 新疆C油藏属于开发早期区块,井资料少、井距较大,采用地震反演等数据进行沉积相研究,可提高研究精度。采用约束稀疏脉冲反演和地质统计学反演两种方法进行地震反演研究,前者受到地震分辨率的限制,纵向上分辨率不能够满足研究需求;而后者可提高反演纵向上的分辨率。本文采用地质统计学反演的储层厚度分布图进行沉积相分析,得到沉积相平面展布图,并总结了沉积相模式,解决了勘探阶段沉积相难以描述等问题,并取得了较好的效果。

| Abstract: | The C oilfield of Xinjiang is in the early development period which has few well data and large well spacing. The study of sedimentary facies using seismic inversion data can improve the research accuracy. The two methods are used for seismic inversion studies, namely constrained sparse pulse inversion and geostatistical inversion. The former is limited by seismic resolution and the vertical resolution can''t meet the research demand. The latter can improve the vertical resolution. The sedimentary facies distribution is obtained by the geostatistical inversion of the reservoir thickness distribution map and the sedimentary facies pattern is summarized. This method solves the problem in describing the sedimentary facies in the exploration stage and the better results are obtained. |
