本文对李兴国和周宪城同志在本刊1982年第2期上发表的“孤岛油田两类河流相储集层及其开发效果分析”一文,提出了不同看法。本文认为:孤岛油田馆陶组河流沉积可分三种类型:馆3—4组为曲流河,馆7—8组为辫状河,特别强调了馆5—6组为网状河而不是辫状河;同时对孤岛油田主要含油层组——馆3—6组的曲流河和网状河的沉积特征作了较为细致的阐述;并根据不同类型河流的沉积特征,对馆5—6组比馆3—4组开发效果要好,进行了初步的解释,所强调的不是层内非均质性差异,而是不同亚相对整个开发层系的影响。
In this paper, Comrade Li Xingguo and Comrade Zhou Xiancheng published in the second issue of 1982, “Gudao Oilfield two types of fluvial facies reservoir and its development effect analysis,” a text, put forward different views. This paper argues that the sediments of Guantao Formation in Gudao Oilfield can be divided into three types: pavilions 3-4 are meandering rivers, pavilions 7-8 are braided rivers, with particular emphasis on pavilions 5-6 as meshed rivers rather than Braided river. At the same time, the sedimentary characteristics of meandering and reticular rivers in Group 3-6 of the main oil-bearing formation of Gudao Oilfield are described in detail. Based on the sedimentary characteristics of different types of rivers, Group 3-4 than the museum group development is better, a preliminary explanation, the emphasis is not on-layer heterogeneity differences, but different Asian relative to the entire development strata of influence.
