陡坡扇储集层三维沉积相建模研究
|
摘要
为研究抽稀井网应用随机模拟方法和多学科信息 (井信息与地震信息 )进行储集层沉积相三维建模和预测的效果 ,结合三维地震资料 ,分别用东营凹陷永 92 1地区全部井 (3 7口 )、抽稀一半井、仅 5口井 ,对其沙河街组陡坡扇储集层进行三维沉积相建模研究。结果表明 ,当波阻抗与沉积相之间有较好的概率相关关系时 ,应用标点过程随机建模方法 ,仅用少量井亦可获得较好的建模和预测效果。这对于勘探或开发早期少井条件下的储集层预测具有较大的实用意义。图 4参 2 1
This paper deals with the effect evaluation of reservoir facies modeling and forecasting using stochastic modeling methods and multi disciplinary information (well and seismic data). Taking the steep slope fan reservoirs in the Paleogene of Yong 921 area of Jiyang Depression as an example, 3 D facies modeling was completed by using the information from all the 37 wells, the half number of wells and the only 5 wells, respectively, as well as combining with the seismic data. The results show that, if good probability correlation relation exists between acoustic impedance and sedimentary facies, excellent effect of 3 D facies modeling and prediction can be achieved by using Stochastic Modeling such as Marked Point Processes method, even if there are only a few wells used. It is of great practical significance in reservoir prediction at petroleum exploration or early development stage when there are only a few wells in study area.
