火山岩储层孔隙结构分类与分布评价:以松辽盆地徐东地区营城组一段火山岩储层为例
Pore structure of volcanic reservoir classified and distribution characteristics evaluated: Taking Member 1 of Yingcheng Formation in Xudong Area in Songliao Basin as an example
摘要
Abstract
In order to make sense of development characteristics of volcanic reservoir and to help empolder volcanic reservoir effectively, pore structure characteristics of volcanic reservoir of the Memberl of Yingcheng Formation in Xudong Area in Xushen Gas Field were studied. 63 cores data and 206 analyzing-testing data were used. The results indicated that the reservoir in study area was middling-low in pore and permeability, and permeability was higher in some areas because of fractures developed. Physical properties and pore structures were different in different lithologies. And heterogeneity of pores strongly developed. Pore and permeability and pore median radius were best parameters to evaluate pore structure. Pore structure could be carved up into four types of Ⅰ, Ⅱ, Ⅲ and Ⅳ.And type Ⅱ and type Ⅲ took the leading roles. Pores and throats distributed inhomogeneously, and they were different in different areas or layers. As a whole, the connectivity of throats was poor. Type Ⅰ and type Ⅱ of pore structure mainly developed in the areas of west and northeast of the central section in the dominating layer of YC1I1 in plane.关键词
