摘要： 本文根据地震、测井及沉积等资料对永安镇油田第三系沙四段储层的成岩作用、储层特征及影响储层性质的主要因素进行了研究。在此基础上对沙四段储层进行了分类并预测了勘探有利地区。作者认为,Ⅰ类储层主要分布在扇中水道部位; Ⅱ类储层主要分布在水道前缘、水道间和扇缘部位; Ⅲ类储层主要分布在扇根部位。同生断层是影响储层性质的最主要的因素之一。

Abstract: The diagenesis, reservoir characteristics and príncipal factors effecting the reservoir properties have been studied for Shasj member of Tertiary in Yonganzhen Oilfield, based on the data of seismic, well logging and deposition, etc., from which the classification and prediction of prospective areas for exploration has been made. It is concluded that Class Ⅰ reservoir was mainly distributed at the mid—fan channels; Class Ⅱ at the front and within channels as well as the fan margin ,Class Ⅲ at the fan bottom. The contemporaneous fault was one of the most important factors effecting the reservoir properties.
