摘要

提出了一种新的有界井函数来处理试井数据。利用基本偏微分方程的拉普拉斯变换,给出了具有物理意义的初始条件和边界条件的解,并证明了其唯一性。提出了一种距离依赖的降程模型。结果揭示了泵送非稳态与稳态之间的联系。讨论了相关的计算问题。给出了利用这些结果处理实际数据的实例。它们说明了结果的高准确性,并且从试井中获得的信息大大增加。

Novel Approach to Well Tests Data Processing
A new bounded well function is suggested for processing well tests data. A solution of the basic partial differential equation with physically meaningful initial and boundary conditions is given using its Laplace transform simultaneously with the proof of its unicity. A model for distance-dependence of drawdown is suggested. Results reveal the link between unsteady and steady state of pumping. Related computational problems are discussed. Examples of processing actual data using these results are presented. They illustrate high accuracy of results and a considerable increase of information obtainable from a well test.
