摘要： 陆相储集层非均质严重,渗透率在不同区块、不同层位的变化规律不同,不能毫不区分地用同一渗透率模型描述。利用流动带指标(Ｉ_(ＦＺ)),将真武油田真12块垛一段六油组(Ｅ_2Ｓ_1~6)储集层划分为四类流动单元,每一类流动单元代表着不同的岩性和物性。在不同类型的流动单元内建立不同的渗透率测井解释模型,该模型计算出的渗透率参数精度更高,且反映了储集层沉积特征和非均质性,为地质建模提供了可靠的渗透率参数。

Abstract: Continental reservoir rocks are normally of serious heterogeneity, and different block areas or different horizons are of different permeabilities. They are hardly described with same type permeability models, but differentiating them. By utilizing flowing zone index(Im), the sixth pay zone group(E2S) in Zhengwu oilfield is divided into four types of flowing units, each representing the different lithologic and physical properties. This paper makes development of well log interpretation models with different permeabilities in different types of flowing units, which can give higher accuracy of permeability parameters, reflect sedimentary characteristics and heterogeneity in detail and provide reliable related parameters for geologic model development.
