摘要

鄂尔多斯盆地马岭地区长81段主要发育长811、长831 2套砂体,砂体薄、横向变化快。利用地震相分析技术,在地震正演分析的基础上,分别采用自组织神经网络波形分类及分频解释技术进行地震相分析,并将2种分析方法的结果进行补充印证,对马岭地区长811砂体、长831砂体地震相进行划分。在此基础上,对地震相单元中的钻井资料进行单井微相分析,并依此建立长811砂体、长长831砂体地震相与沉积相的对应关系,将地震相转换为沉积相,研究砂体的分布特征及横向变化规律,对储层进行预测。在该区的实际应用中已取得较好效果。

Abstract

There are two sets of sands chang811 and chang831 in the chang81 reservoirs in the Maling oilfield of Ordos basin.The sand body is thin,associated with the large thick change in horizontal.Based on seismic forward modeling,we use the technique of waveform classification and frequency-divisional to interpret the seismic facies,and classify the distribution of chang 811 and chang 831 seismic facies.By means of comparing the seismic facies with sedimentary microfacies of single well,we setup the correlation between seismic facies and sedimentary facies.We draw the distribution and horizontal change of sandstone and predict the distribution of reservoir.The desired result has been used successfully in this region.
