Intelligent well completion system

A intelligent well completion system is a remote measurement and control system which is with a downhole sensor and can collect correlative data on real-time. It allows operating personnel to monitor and control on real-time the oil/gas production of multi-zone of single-well or the oil/gas production of single wellbore of a multi-branching well. And it can also reduce a good deal of downhole remedial operation during well production, therefore it maintains the effective production rate and gains higher oil and gas recovery factor. By controlling the flow behavior of formation fluid, the system can restore reservoir energy, increase oil and gas production, maintains formation energy and postpones formation water invading producing zone. The higher recovery factor and the lower frequency of the downhole remedial operation can reduce the cost of oil and gas production. The intelligent well completion system is especially suitable to adjustment wells and the oil wells requiring higher repairing expenses, such as offshore oil wells, deep water oil wells, multi-branching wells, horizontal extending wells, vertical wells and remotely operated oil wells.
