摘要
陆相储层隔夹层是形成储层流体流动非均质的主要因素之一,也是储层精细表征的重要内容。全面认识隔夹层的成因、特征、分布和识别方法对精细表征油藏地质特征,研究剩余油分布,进而采取有效的工程措施都具有重要意义。陆相储层隔夹层主要分为泥质隔夹层、钙质隔夹层和物性隔夹层3大类。根据岩性和物性特征,可识别取心井隔夹层类型;根据不同隔夹层的测井响应特征可识别非取心井的隔夹层。隔夹层的各种电测曲线绘制成蜘蛛网图模式,泥质、钙质和物性隔夹层具有不同的网形模式,可作为隔夹层的划分依据。
One of the major factors, controlling the movement of fluids in reservoir of clastic rock, is the intercalation in non-marine reservoir which can be divided into three types, such as muddy intercalation, calcicolous intercalation and petrophysical intercalation. According to such division, types of intercalation in the coring well are identified ; and the types in the non-coring well are determined from their logging responses. Various electric logging curves of intercalations are plotted as spider-web charts. Therefore, different spider-web charts may be used to distinguish the different types of intercalation.
