Abstract: The authors have studied the water-drive behavior of L pool in the Laojunmiao oil field, based on the principles pertaining to oil and water flow and in reference to the method of studying displacement curver used by petroleum engineers Tong Xianzhang, Chen Yuanqian, etc. The importance and necessity of intensifying water injection is stressed for an oil field like Laojunmiao with such a long history. Their research indicates that linear relationship exists not only between such variables as W_p, WOR, F_w and N_p, R_o, S_w, but also between and F_w. Formulas have been worked out showing the relationship of factors influencing the water drive production of L pool that may be used for predicting reservoir performance. Feasibility of this method is established by a comparative study.

摘要： 本文根据油、水两相渗流理论,参见^[1,2]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。
