一趟管柱挤封任意层工艺技术是在已有成熟的挤注、封堵管柱工艺的基础上,对挤注桥塞、坐封工具及管柱工艺进行改进而成,其主要针对油水井生产过程中,因层间窜通、管外窜、边底水锥进等原因造成的高含水问题;改进后的管柱工艺技术,能将可钻桥塞的坐封、验封及挤注桥塞的坐封、挤注等多项工序在一趟管柱内完成,达到一趟管柱对油水井任意层段的封堵;该技术的应用能有效减少管柱的施工时间、成本和风险,可对高含水层及管外窜进行有效挤注、封堵作业。
A trip to the column squeeze any layer of technology is in the already mature squeeze, plugging the column process, based on the squeeze bridge plug, setting tools and pipe string process made of improved, which is mainly for oil In the process of well production, the problem of high water content is caused by such reasons as channeling between layers, channeling outside of pipes, coning of edge water, and so on. The improved column technology can improve the setting, inspection and crowding of drillable bridge plugs Note a set of bridge plug, squeeze injection and other processes in a trip to complete the column, to achieve a column of oil and gas wells at any interval of the block; the application of the technology can effectively reduce the construction time of the column, the cost And risk, can effectively squeeze the high aquifer and tube channeling, sealing operations.
