本文以API法为基础,把查图试算改为公式计算,通过数列能自行根据井筒相态的实际情况分为二段、三段或四段来求取流压值。此方法不但程序简便,而且计算精度高。
Based on the API method, this paper changes the test chart calculation to the formula calculation. The series can be divided into two, three or four stages according to the actual situation of wellbore phase to obtain the pressure value. This method not only has the advantages of simple procedure but also high calculation accuracy.
