摘要
塔河油田志留系以细砂岩、粉砂岩、泥岩为主,夹有灰岩、砾岩等,呈低孔低渗的特点,录井及取芯均有良好的油气显示。本文针对塔河油田志留系由于储层含灰质,使得划分地层难,物性研究少等不足,分析了志留系储层物性特征,统计了各类岩性测井曲线统计特征,为测井资料评价储层打下了良好的基础。
Low porosity and low permeability are the features of the formation in Silurian at Tahe Oilfield which mainly constituted by finestone, siltstone and mudstone with interbedded limestone and conglomerate, and the results of logging and coring both give a good SO＆G. This paper does a research on the features of Silurian reservoir and thestatistical well logging data, considering some problems such as limestone in the reservoir which makes it difficult to distinguish the layer and lacking of the research. All the work will be a good support for reservoir evaluation.
