气井不关井产能试井在玛河气田的应用

在气田投入开发时,通常可利用产能试井对气田产能进行了解。气井产能是气藏工程分析中的重要参数之一。因此,测试和分析气井产能具有重要意义。以往采取定期关井测试,由于要影响正常的供气,导致生产受阻。而不关井产能试井,是在气井正常生产下进行的,不会影响到气田产量,且不受时间和供气限制。其所得产能计算方程又能反映单井的实际生产能力,符合气井的生产状况。该方法现场可操作性强、准确性高,是解决常规回压试井与生产供气矛盾的一种简单有效的方法。

The application of not shut-in deliverability test in Mahe gas field

When the gas field was developed,it’s productivity can be reflected by deliverability test.Gas well productivity is one of the important parameters to analyse gas reservoir engineering,so the test and gas well productivity analysis is significant.The method that shut-in test regularly is used before often hinders the gas production,and affects the normal gas supply.But the not shut-in deliverability test that operates in the normal condition,which won’t affect the production of gas field and could not be limited by time and gas supply.The productivity equation that based on the test not only reflects the actual productivity of single well,but also conforms with the productive condition.Not shut-in deliverability test is feasible and the result is accurate,which is a simple and effective method to solue the conventional back pressure test and the contradiction between production and gas supply.
