测试-改造-封堵-回采一体化试油管柱技术

摘要

塔里木盆地属缝洞型碳酸盐岩储层，在试油时易喷易漏、井控安全隐患突出，为了解决此类问题，研发了以HP-1AH封隔器为核心组件的测试-改造-封堵-回采一体化工艺管柱，解决了该类储层试油作业易漏易喷井控风险的技术难题；同时减少了多次压井作业对储层造成的二次污染，缩短了施工作业周期，节约了成本，现场应用效果良好。%The Tarim Basin is the typical carbonate reservoir ot caves and hssures which could cause teaks and gushes of oil during formation testing, posing a safety threat to well control practices. This paper had successfully solved this problem by coming up with a tubular column with HP-1AH packer its core component which is capable of multitasks including testing, remolding, plugging and recovering. Moreover the technique could mitigate secondary pollution by repeated well killing operations, shorten working period, cut costs and proved effective in practices.
