| 摘 要： | 宝浪油田属于油气比较高的低渗透油藏,在试井时井筒储存效应长时间存在,使常规的压力恢复试井时间很长。为解决低渗透挥发性油藏不稳定试井占产时间太长的难点问题,在B103井试用了变流量(不关井)试井方法。通过现场测试计算和分析表明,该方法的计算结果正确、测试工艺及其分析过程简单,便于现场应用。由于开井试井井筒储存效应减少,测试时间缩短,使试井对油井生产几乎不产生影响,有效地提高了试井的经济效益和油井的开发管理水平。

| Abstract: | Effect of wellbore storage exist commonly in a long time after well testing in Baolang oilfield,a low permeability reservoir with relatively high GOR,leading to a long time needed for conventional pressure buildup test operation.Variable rate test method was utilized in Well B103in order to solve this problem.Field test calculation and analysis revealed that calculation results were accurate,testing technologies and analytical proce-dures were simple and it was suitable for field applica-tion.Open well test operation remarkably reduced effect of wellbore storage,shortened test time and fundamen-tally elim inated the impacts of well testing on produc-tion,thus im proved economic benefits of well testing and development man agement levels. |
