摘要

针对致密砂岩气藏的储层特征及渗流机理,建立并求解了考虑储层应力敏感性和裂缝导流能力的致密砂岩气藏压裂井不稳定渗流数学模型,进一步开发出应力敏感性致密砂岩气藏压裂井产能递减典型曲线图版,利用图版拟合可以求取致密砂岩气藏应力敏感储层参数及压裂工艺参数,形成一套快速有效的致密砂岩气藏压裂井动态反演技术及动态产能确定方法。通过苏里格气藏压裂井实例分析,验证了该应力敏感性致密砂岩气藏压裂井动态反演技术方法的可靠性,有助于致密砂岩气藏的高效开发。

Abstract

Considering the special geologic characteristics of tight gas reservoir,the paper established an unsteady flow model of fractured wells in stress-sensitive reservoirs and the perturbation transformation mechanism is introduced to solve the adverse impacts of stress-sensitivity on the nonlinear equations as well.On this basis,a series of production decline type curves were drawn for fractured well in stress-sensitive reservoirs.In addition,both pressure/production coupling approach and the wellbore feature parameters determination method are developed successfully.With the curve matching method,stress-sensitive media and fracturing parameters could be obtained accurately and conveniently.Case analysis of Sulige gas reservoir have demonstrated the usage of above methods and confirmed the reliability of dynamic inversion technical method proposed in this paper.
