| 摘 要： | 火山岩储层建模研究是一个世界性难题。近年来 ,国内外在含油气盆地的火山岩中发现了大量的油气藏。为了探索火山岩储层物性的空间分布特征 ,作者选取了松辽盆地徐家围子地区火山岩发育的营城组为研究目的层 ,以火山岩相分析为基础 ,以基于相分析的神经网络技术为手段 ,通过多种参数的选取和计算 ,尝试性地建立了该区火山岩储层地质模型。该模型表明 :层状火山机构比块状火山机构的物性好 ;多相火山机构比单相火山机构物性好 ;裂缝发育的火山机构比裂缝不发育的火山机构物性好。基底涌流相、火山空落相、火山沉积相是有利的储集相带。

| Abstract: | Volcanic reservoir modeling is still a challenge task in reservoir geology. But a number of oil and gas pools have been found in the volcanic rock home and abroad for last few years. In order to study the spatial features of the volcanic reservoirs, Yingcheng Formation, located in Xujiaweizi region of Songliao Basin, has been selected as target zone. Based on the analysis of volcanic eruption facies, many parameters for modeling were chosen and calculated by using facies controlled Neural Network technique, and finally a volcanic reservoir model was built in this region. It shows that the petrophysical features of layer, multi facies and crack volcanic mechanisms are better than block, mono facies and non crack ones respectively. The base surge flows facies, pyroclastic fallout facies and eruption sedimentary facies are the promising zones for oil and gas exploration. |
