【摘要】：随着蒸汽吞吐开采方式进入后期,储层非均质性对开发效果的影响日益凸显。以辽河西部凹陷某试验区为例,综合岩心、镜下薄片、测井、分析测试等多种资料,实现储层发育特征表征。研究区目的层属扇三角洲前缘沉积,由于水下分流河道的频繁分流改道,砂体相互切叠,储层非均质性强烈。优选充分反映储层性质影响因素的参数,基于经典的聚类分析软件平台,实现扇三角洲沉积储层定量评价。将目的层储层划分为Ⅰ类、Ⅱ类、Ⅲ类和Ⅳ类4种类型,储层分类正判率超过85%。不同类型储层发育明显受沉积相控制,Ⅰ类和Ⅱ类储层多位于水下分流河道和河口砂坝的位置,而Ⅲ类和Ⅳ类储层多位于水下分流河道间砂或前缘席状砂的位置。不同类型储层在转换热采方式时应该区别对待。
[Abstract]:With the development of steam huff and puff, the influence of reservoir heterogeneity on the development effect is becoming more and more prominent. Taking a certain experimental area in the western depression of Liaohe River as an example, the reservoir development characteristics can be characterized by synthesizing the data of core, thin slice under mirror, well logging, analysis and test, etc. The target layer in the study area belongs to fan delta front sedimentation. Due to the frequent diversion and overlapping of sand bodies in underwater distributary channel, the reservoir heterogeneity is strong. Based on the classical clustering analysis software platform, the quantitative evaluation of fan delta sedimentary reservoir is realized. The target reservoir is divided into four types: class 鈪，
