地震波形指示反演在东营凹陷王家岗地区沙四上亚段滩坝砂的应用
以东营凹陷王家岗沙四上亚段滩坝砂为例,在层序地层格架建立的基础上,利用沉积学原理,基于贝叶斯理论将地震、测井和地质统计学信息融合为地层模型参数的后验概率分布,采用Metropolis-Hastings抽样算法对后验概率分布随机抽样,获得反演解,从而预测有利滩坝相带。结果表明：东营凹陷王家岗地区沙四上亚段低位域发育滩坝砂,其中准层序组2沉积时期以坝砂为主,砂体厚且横向分布稳定,而准层序组1和准层序组3沉积时期滩砂和坝砂间互发育,砂体厚度相对较小;湖侵域和高位域主要发育碳酸盐岩滩坝,滩坝砂零星状分布。该方法体现了相控的思想,预测结果更符合地质规律,在东营凹陷沙四上亚段滩坝储层预测中取得了较好的效果...

| Abstract_FL | The focus of the paper is the upper part of the fourth member of Shahejie Formation (Es4s) in Wangjiagang area,Dongying Depression.Based on Bayesian theory,a posterior probability density function of subsurface models was developed by establishing sequence stratigraphy framework,integrating the principles of sedimentology and information from seismic,well logs and geostatistics.The Metropolis-Hastings algorithm was applied to obtain an exhaustive characterization of the posterior probability density to predict the favorable beach-bar sedimentary facies.Results show that in the beach-bar sand development in the lowstand system tract (LST) of the Es4s,the bar sand is well developed,relatively thick,has large scale distribution,and less lateral variation in the second order para-sequence.The bar sand is interbedded with beach sand,and the overall thickness of the sand is relatively small in the first and third order para-sequences.The lacustrine transgressive system tracts (TST) and the highstand system tracts (HST) are mainly developed the carbonate beach-bar,and are less developed in sandy beach-bar.The aforementioned method is facies-controlled,which yields results that are more consistent with the geological observations.The proposed method works preferably in the Es~,but may also be applied to other types of reservoirs. |
