Intelligent well system is the well that has a set of equipment fixed in the down hole including sensing devices,data transmission system and operating devices for information acquiring,data gathering and decision analysis.By this remote control process,the smart well system can ultimately optimize well deliverability;it is used more and more often in oil fields with its stability and control technique.At present,the main intelligent well systems in the world include SCRAMS,Direct Hydraulic,Digital Hydraulic that belongs to WellDynamics Company,InForce and InCharge that belongs to Baker Oil Tools Company,RMC that belongs to Schlumberger Company.This paper compares different types of systems and their characteristics,recommending the InCharge system as the intelligent well system for East China Sea Oil Field according to its geological and reservoir conditions.
