Study of the Intelligent Completion System for Liaohe Oil Field

The intelligent well technology is one of the most important technologies with the capability of optimizing reservoir management, increasing recoverable reserve, enhancing oil recovery and speeding up the oil exploitation. In order to improve the reservoir development efficiency in our country, reduce water cut in oil well, expand reserve and improve the oil field development benefit, this paper studied the important four sections (the down-hole monitoring system, the data transmission system, the intelligent optimization system on the ground and the production control system), optimized the down-hole gauges and transmission facilities, developed an intelligent optimization system and an inflow control valve (ICV) system with self-owned intellectual property right, and then completed the first set of intelligent completion system(ICS) in China, thus realized a measurable, controllable and optimizable intelligent oil well exploitation. Preliminary experiments have shown the stability and reliability of the system, according to intelligent and advanced exploitation, the oil production of Lei632 oil well has been about 10.5% higher than before.
