摘要：

在直角坐标系下,将井底压力恢复资料绘成P-t曲线,在曲线上任取两个时间点(t1,t2),第 3点(t3)取其平均值,读出对应的P1,P2和P3值,并求出时间曲线的斜率,即可根据图版求出产率指数。选点时,t1和t2间隔不宜过小,t1一般选取 40min左右,t2选取 300min左右。该方法主要依据段塞流测试理论而建立。中国东部某油田采用此法所得预测结果与实际测试结果基本相同。

Abstract:

Use data of bottom pressure restoration of well with right angle coordinate system to draw P-T curve,and then chose two time-points(t1,t23) from the average value,read out corresponding P1,P2 and P3 value,produce time curve slope and productivity index on the basis of the plate.Interval between each point shall be chosen as following rule;interval between t1 and t2 shall not be too small,40mm for t1 and 300mm for t2.The establishment of this method is mainly on the basis of theory of slug flow test.Predicative results got from an oil field in eastern China by this method are almost as same as practical testing results.

Key words: non flowing well, slug flowing test, productivity, application
