摘要
气井二流量试井在鄂尔多斯盆地其他致密砂岩气田已广泛使用,在长庆气田、延安气田的应用效果良好,尤其针对临兴气田上产任务重、常规试井测试成本较高,不关井、测试时间短的优势具有广阔的应用前景。目前优选3口不同类型的井,即高产压裂井、高产射孔井、积液井,采用井口+井下压力监测工艺,1口压恢+二流量、2口二流量。以井下压恢验证井二流量试井解释结果可靠性,以井下二流量试井验证井口二流量试井解释可靠性。该次试验结果显示,井口、井下测试误差小于10%,测试周期缩短6 d。根据该次试验结果,对不同类型井选择预制适应的试井工艺,达到测试综合效益最大化。
The second flow test of gas well has been widely used in other tight sandstone gas fields in Ordos Basin,and the application effect is good in Changqing Gas Field and Yan'an Gas Field.Especially for the advantages of heavy production task,high cost of conventional well testing,no shut-in and short testing time in Linxing Gas Field,it has a broad application prospect.At present,three different types of wells are selected:high-yield fracturing wells,high-yield perforating wells and fluid accumulation wells.The wellhead+downhole pressure monitoring technology is adopted,one pressure recovery+two flow rate and two two flow rate.The reliability of two-flow well test interpretation results is verified by downhole pressure recovery test,and the reliability of wellhead two-flow well test interpretation is verified by downhole two-flow well test.The test results show that the test error of wellhead and downhole is less than 10%,and the test period is shortened by 6 days.According to the results of the test.The well testing technology suitable for prefabrication is selected for different types of wells to maximize the comprehensive benefit of testing.
