摘要
在试油阶段 ,对非自喷井 ,特别是稠油井的产能测试有较大的困难和局限性。采用“射孔—测试—排液”一体化三联作试油技术 ,既能满足常规测试取资料的要求 ,又能利用排液设备实现长时间连续产能测试。同时 ,采用有机盐射孔液保护已射开的油气层 ,并利用水力泵可加温、加药降粘的特点 ,能较好地满足非自喷高凝稠油井产能测试的要求。该技术经现场应用 ,取得了良好的效果。
To no flowing and heavy oil wells,the technology of using three combination testing technique of perforation,testing and unloading not only feeds the need of getting data by conventional test,but also realizes the continuous potential test for a long time with flowing back equipment.Meanwhile,utilizing organic salt as perforating fluid to protect perforated formation and the feature of the hydraulic pump to reduce viscosity by raising temperature and adding chemicals,those can complete the continuous potential test in no flowing and heavy oil wells properly.The actual application of it has got a good result.
