介绍了一种井下智能分层采油技术,一趟管柱实现井下找水、堵水、生产、调层、测试等多项功能。用封隔器将井下各层位封隔,管柱上对应的每一个目的层段安装一套智能开关器。找堵水过程中井下智能开关能按照设定的时间顺序自动打开或关闭油层,实现油井的找水、堵水措施,达到任意选层开采,降水增油的目的。同时在生产过程中,内置压力计可连续监测分层压力资料,分析油层分层参数(分层压力、渗透率、污染系数)等资料,为精细掌握油藏动态特性提供依据。
A smart layered oil production technology is introduced. A series of pipe strings can find water, shut down water, produce, adjust layers and test many functions in the downhole. The packer will be downhole layers of isolation, the corresponding column on each column to install a set of intelligent switch. Looking for plugging process in the underground intelligent switch can be set in accordance with the order of time to open or close the reservoir, to find the water wells, plugging measures to achieve any layer selection, precipitation, oil purposes. At the same time, the built-in pressure gauge can continuously monitor the data of the stratified pressure in the production process and analyze the stratified parameters (stratification pressure, permeability and pollution coefficient) of the strata so as to provide a basis for grasping the dynamic characteristics of the reservoir.
