Oil nozzle action, which has the disadvantage that currently available technology is only capable of switching the flow of each interval, it is impossible to realize the stepless-adjustment of flow
Section, simultaneously because derailing switch is powered using down-hole battery, therefore service life is constrained by battery life.Flow down-hole
Dynamic control subsystem is for being acquired monitoring, main measurement method to data such as the temperature of each interval in down-hole, pressure and flows
It is including electronic type and optical fiber type, also many at present sensor to be powered using down-hole battery, measurement is affected by battery life
Frequency and duration are all restricted.Simultaneously as prior art down-hole flowing control subsystem and down-hole dynamic monitoring subsystem
It is detached, without becoming one so that tubular column structure is complex, is unfavorable for Contraction in Site.
