油田地面注水系统规划技术研究

油田地面注水系统是油田注水系统的重要组成部分,其规划关系到整个系统的投资和运行成本。对于油田地面注水系统的规划技术进行了研究,采用分级优化的策略,将整个系统的规划问题分解为注水支线管网的规划和注水干线管网的规划两部分。在注水支线管网的规划中,提出了以系统投资和系统可靠性为目标的数学模型,并对模型进行了求解。针对注水干线管网的特点,通过对注水站站址的优选、主干线的走向及干线与支线交点的确定,在满足工艺要求的条件下,实现对注水干线管网的优化。使管线费用达到最少。

REASEARCH OF OIL FILELD GROUND WATER INJECTION SYSTEM PROGRAMMING TECHNIQIUE

The ground water injection system is the important part of oil field flooding system , its programming influences the investment and running cost of total system. The programming method of the ground flooding system was studied in this paper and the total optimization problem was separated two parts , the programming of water injection branch line and that of water injection trunk line. In the programming of water injection branch line , a mathematical model aimed at system investment and reliability was proposed , the resolve method of this model was also provided. In view of the features of water injection trunk line , the optimization of trunk line and the minimum investment was reached through optimization of pump station position , defining the alignment of main trunk line and the intersection point of trunk line and branch line under the situation of meeting the demand of water injection technology.
