decline curves

Through the research on oil/gas reservoir production decline and linear optimal method and related literatures,new decline curve research provides a new simple method of solving the equation.

通过对油气藏产量递减的研究、线性最优化方法的分析研究及文献[1]提出的这种新型递减曲线的研究,提出了解这种方程的一个简单求法。

Based on Arps equation experienced degradation curves(exponential degradation、conciliatory degradation、hyperbolic degradation) and actual data of productivity degradation,we use Arps equation experienced degradation curves to deal with the data and find the combinatorial relation of the variables of Q、N_p and Q_t.

提供了应用计算机自动拟合曲线法和筛选法进行产能衰减曲线分析,以Arps经验递减曲线方程[1]既(指数递减、调和递减、双曲线递减)为理论基础,以油田产能衰减的实际数据为依据,用Arps经验递减曲线方程进行处理,找出(Q、Np、Qt)的直线变量组合关系。
