摘　　要：热水驱能够降低原油黏度,改善水油流度比,降低残余油饱和度,是稠油油田开发的主要方式之一,探索热水驱开发的主控因素对于热水驱方案设计具有重要意义。本文通过调研陆地油田地质油藏参数和开发效果,选取油层有效厚度、净毛比、渗透率、原油黏度、平面变异系数、注热水温度为目标参数,引入变异系数评价影响热水驱采收率的主控因素,研究表明:注热水温度和油层有效厚度是影响热水驱采收率的主控因素,研究结果可以指导热水驱油田选取方案和方案设计。Hot water flooding can reduce crude oil viscosity,improve water-oil mobility ratio and reduce residual oil saturation,which is one of the main ways of heavy oilfield development.It is of great significance for the design of hot water flooding scheme to explore the main control factors of hot water flooding development.In this paper,by investigating geological reservoir parameters and development effects of land oilfields,effective reservoir thickness,net gross ratio,permeability,viscosity,plane variation coefficient and hot water injection temperature are selected as target parameters,and coefficient of variation is introduced to evaluate the main control factors affecting the recovery efficiency of hot water flooding.The research shows that hot water injection temperature and effective reservoir thickness are the main factors affecting the recovery efficiency of hot water flooding.The research results can guide the selection of hot water flooding oilfield and project design.
