气井稳定渗流理论与应用

Application of gas well stable flow

针对按传统的二项式规律处理气井稳定试井(亦称产能试井)资料,有50%～60%的气井试井结果不服从二项式规律的问题,提出了用二次三项式和三次三项式研究气井产能。首先从理论上研究了上述两个方程,提出了应用二次三项式处理稳定试井资料的方法和步骤,以及三次三项式方程处理高压低渗特殊气井稳定试井资料的方法和步骤。通过矿场资料的应用和研究表明,该方法是可行的,同时对上述方程的理论研究意义和实用性作出了评价,为矿场工作人员优选稳定试井资料的处理方法提供了依据。

Gas Well Testing stability(just as gas well production capacity) analysis method is the steady flow of gas fields in the production of important applications.We used three second-and third three-equation instead of the traditional binomial,are two new theoretical formula.This paper from theory and research on the mechanism of the above two equations,on the basis of this proposed three-equation of the second Test stability of information processing methods and steps,and three three-equation dealing with special high-pressure gas permeability Well stability testing the method and steps.And then through the field application and research on the equation of theoretical research and practical significance to the evaluation,to the quarry selection of staff stability Testing the handling of information provided a basis.
