摘    要:在东营凹陷胜坨油田坨71区块的有利储集砂体预测中,探索应用砂体随机模拟的结果直接对无井区进行有利储集砂体分布预测。综合测井、地震资料.应用示性点过程随机模拟方法,建立了20个等可能的渗透性砂体分布的模拟实现,在对各模拟实现进行概率统计分析的基础上,对模拟结果进行不确定性评价.结合对概率大于0.5和0.7的渗透性砂体的厚度统计结果、构造背景及附近井油层分布情况,预测出坨71井以东和坨深1井东南的2个有利储集砂体分布区。应用砂体随机模拟的结果直接预测无井区的有利砂体分布,有利于降低滚动勘探风险。图5参18

关 键 词:东营凹陷  随机模拟  储集层建模  砂体预测

Abstract:Stochastic modeling based on well logs and seismic data of Tuo-71 Block in Dongying Depression indicates that favorable reservoir sand bodies of un-drilled areas can be predicted. In statistical and probability analyses of permeable sands modeled in several realizations, uncertainty evaluation was applied for the modeling results. According to the thickness of the permeable sands with probability greater than 0. 5 and 0.7, as well as the structure and distribution of the oil-bearing formation in the well nearby, two favorable reservoir sand bodies are predicted to occur in the area, on east of well Tuo-71, and the other southeast of well Tuoshen-1.
Keywords:Dongying Depression  stochastic modeling  reservoir modeling  sand body prediction
