Abstract

ABSTRACT As it is known, many reservoir formations have an irregular permeability profile. Such heterogeneity leads to irregular profiles of the injected water progression and its unequal distribution, if traditional technology is used. High heterogeneity of the reservoir leads to early water breakthroughs and clogging of production wells, in addition: some areas containing naphtha remain difficult to access. The relevance of the issue under consideration is due to the demand to increase oil recovery from reservoirs. The purpose of the paper is to analyze methods of influencing a non-uniform formation. This paper provides an overview of studies aimed at greater reservoir coverage by exposure when developing non-uniform reservoirs; The main parameters of the formation that affect the decrease in the coverage of the reservoir by exposure are identified, and the improvement of the impact on the inhomogeneous formation by changing the density of perforation holes is considered. The materials of the paper are of practical value, since hydrodynamic modeling was carried out to determine the effect of changes in the density of perforations on the coverage of the formation.

非均质油藏波及效率的提高

摘要众所周知，许多储层具有不规则的渗透率剖面。如果使用传统技术，这种不均匀性会导致注入水进程的不规则剖面及其不均匀分布。储层的高度非均质性导致早期水突破和生产井堵塞，此外：一些含有石脑油的区域仍然难以进入。考虑中的问题的相关性是由于需要提高油藏的石油采收率。本文的目的是分析影响非均匀地层的方法。本文概述了在开发非均匀储层时，旨在通过暴露扩大储层覆盖率的研究；确定了影响暴露降低储层覆盖率的地层主要参数，并考虑了通过改变射孔密度来改善对非均质地层的影响。由于进行了流体动力学建模以确定射孔密度变化对地层覆盖率的影响，因此本文的材料具有实用价值。图形摘要
