Abstract

Abstract: Fracture is taken as a set of point sources (or sinks) for using Green's Function to study the problem of transient flow in closed reservoir with finite-conductivity vertical fracture.Program has been written to calculate the results,and some results have been compared with Benjamin's.It is found that the two different methods gave an excellently close calculation results.This study can be used in well test,performance history match and prediction for the fractured wells,and the importance of the study lies in building of a foundation in theory and method for studying the transient flow in closed reservoirs that include multi-fractured wells.Therefore,it is a significant practice.

Key words: vertical fracture, unstability, transient flow, Green’s function, closed reservoir, finite-conductivity

摘要： 把裂缝看作点源(汇)集合,应用格林函数法,对含有有限导流能力垂直裂缝井的封闭地层中不稳定渗流问题进行了研究,并编制了程序,与Benjamin等人的研究结果进行了比较,虽然所用的方法不同,但结果是一致的.该研究结果不仅可应用于压裂井的试井解释、参数拟合及产能预测,而且更重要的是在理论及方法上为含有多口压裂井的封闭地层中不稳定渗流规律的研究奠定了基础,具有理论和实际意义.
