引入比产能进行气井产能评价引发的思考

Thinking for gas well's flow potential evaluation by introducing relative flow potential

气井产能的评价,理论基础已相当成熟,实际生产中也已形成相当成熟的方法,具体的操作过程亦不复杂。然而在实际运用中由于受到资料数量和质量的制约,稍不留意就会使得评价结果与实际产能出现较大差异,从而影响开发技术政策的制定、气田的开发效果及气田的经济效益。笔者引入比产能方法,在对XXX气田进行产能评价过程中,遇到一系列难以用常规方法解决的问题,由此引发产能评价的思考,对其原因以及对实际气田开发的影响进行分析和探讨,并提出了相应的应对措施。

There are many methods to evaluate flow potential of gas well which has mature theory base and simple processing course.However,due to the quantity and quality of the well data,the calculation result is quite different from the actual flow potential in practice,which will affect development plan and the corresponding commercial efficiency.The writer encounters some tender problems when calculate the flow potential of XXX gas filed,then think it over and analyse and discuss its reason,and propose measures to solve these problems finally.
