This paper ptesents a technique for seismic lithology inversion which constructs an initial brond-band tripedance model based on seismic toformation and constrained by geological and logging information. The initial model is refined with a random iterative algorithm to obtain an ultimate impedance model with high resolution. Theoretical computation and real data processing show that the technique has advantages over conventional seismic lithology inversion techniques. As a result,the ultimate model can be used as a basis for calculation of various strata petroproperties.

本文阐述的是一种地震岩性反演方法。这种方法是以地震信息为基础,以地质、测井信息作为约束条件,提出一个宽频带的初始波阻抗模型,并使用一种随机迭代算法对初始模型进行修正,以求得一个具有较高分辨率的最终波阻抗模型。此方法与传统的地震岩性反演方法相比较有许多优点,这在本文的理论计算和实际资料处理中都得到了证明。这样,就可直接使用求得的优化宽频带波阻抗模型,进一步求取地层的岩性和孔隙度等物性参数。

The upper paleozoic sandstone reservoirs in Tabamiao block of north E'erduosi Basin are of the characteristics of low porosity and permeability.The well log informations change with the relative content of the quartz and debris in rock solid phase and are seriously affected by mud filtrate invasion,which makes the difficulty in interpreting reservoir's physical property and hydrocarbon-bearing performance increased.In the study,on the basis of the core analysis data,the rock matrix was classified as quartz type,debris type and clay type and,by using BP neural network to make lithology inversion,the lithological profile conforming to objective practice was set up.On the basis of lithologic identification,the reservoir's porosity and permeability was calculated with multivariate statistics according to the log response of different rock composition.Begining with the reservoir's rock and pore structure,through a comprehensive analysis of the relation between lithology and electric property,using dynamic method to determine the cementation factor (m) and saturation exponent (n) and acquring the respective m and n value according to the three intervals of porosity (<5%,5-10% and >10%),the precision of gas saturation calculated with Archie equation was raised.In addition,based on the core analysis data,the relational expression for irreducible water Saturation was established.A good result was obtained by applying above-mentioned interpretation method to Tabamiao block and,through verification,it is proved that its coincidence rate reached over 80%?

鄂尔多斯盆地北部塔巴庙区块上古生界砂岩天然气储层具有低孔低渗特点 ,测井信息随岩石固相中石英、岩屑相对含量的高低而变化 ,并且受泥浆滤液侵入影响较为严重 ,增大了储层物性和含气性解释的难度。在研究中 ,根据岩心分析资料将岩石骨架分为石英类、岩屑类和粘土类 ,利用BP神经网络进行岩性反演 ,建立了符合客观实际的岩性剖面 ;在岩性识别的基础上 ,根据各类岩石成分的测井响应 ,利用多元统计方法 ,计算储层孔隙度、渗透率 ;从储层岩石和孔隙结构入手 ,通过岩—电关系的综合分析 ,采用动态法确定胶结指数m和饱和度指数n ,按照孔隙度小于 5 %、5 %~ 10 %和大于 10 %三个区间 ,分别求取m、n值 ,提高了阿尔奇方程计算含气饱和度的精度 ;另外 ,根据岩心分析资料 ,建立了束缚水饱和度的关系式。上述解释方法在塔巴庙区块的实际应用中取得了很好的效果 ,经测试成果验证 ,符合率达到 80 %以上
