周43块为疏松砂岩油藏,目前均处于低采出程度、高含水期。因储层出砂严重,目前开发效果不理想。通过项目研究评价开发效果,分析油藏存在的主要问题以及潜力,动静结合,研究水淹特征及剩余油分布现状,结合生产资料、剩余油分布研究成果和沉积微相制定下步调整对策。
Week 43 blocks of loose sandstone reservoirs, are currently at a low level of mining, high water cut period. Due to serious sand production, the current development results are not satisfactory. Through project research and evaluation of development results, the paper analyzes the main problems existing in oil reservoirs and their potential, the combination of movement and hydrology, studies the characteristics of flooding and the distribution of remaining oil, and makes the following adjustment measures in combination with the production data, research results of remaining oil distribution and sedimentary microfacies.
