本文根据油、水两相渗流理论,参见对驱替曲线的研究方法,对L油层的水驱特征进行研究。从水驱特征的角度进一步论证了后期开发的重要性和提高液量采油、加强注水的必要性。研究表明,不仅W_p、WOR、f_w与N_p、R_o、 S_w等动态变量间存在线性关系,△S/△V·100、△η/△V、q_o/△V·100与f_w之间亦存在很好的线性规律。研究中,本文利用矿场资料建立L油层水驱特征关系式,预测油藏动态,并径比较,证实此法作为一种动态指标预测方法是可行的。
In this paper, according to the oil-water two-phase seepage theory, see the research method of displacement curve, the waterflooding characteristics of L reservoir are studied. From the perspective of water flooding characteristics, the importance of later development and the necessity of raising oil production and enhancing water injection are further demonstrated. The results show that there is a linear relationship between W_p, WOR, f_w and N_p, R_o, S_w and other dynamic variables. There is also a linear relationship between △ S / △ V · 100, △ η / △ V, q_o / △ V · 100 and f_w Good linear rule. In the study, this paper established the relationship between the waterflooding characteristics of reservoir L and the reservoir dynamics by using the mine data and compared them with each other to confirm that this method is feasible as a dynamic index prediction method.
