摘要
针对新区稳产时间以及递减期递减余率大小难以确定等问题, 通过对中原油田61个独立小区块进行分析对比, 得出采油速度与稳产时间, 不同采油速度下无因次采油速度与时间关系曲线, 对于新区开发预测稳产时间以及预测递减期产量变化有着重要意义。
Abstract
In som e fresh deve lop ing zones, the stable production
per iod and decline rate var iation are difficult to de term ine. To
so lve this prob lem, deve lop ing states o f 61 sepa rate
developing zones have been analysed and a re la tion curv e
betw een d im ension less ra te of o il produc tion and stab le
production per iod under consideration o f rate o f o il production
w ith stable production period and dec line rate has been
developed. This novel me thod is he lpful to predicate stab le
production per iod and produc tion va riation.
Keywords:

production, stab le production per iod, decline rate;
