Technical Introduction:
Using the horizontal well top circulation filling technology, the screen tube and wellbore annulus are continuously filled to isolate particles. Using the flow control function of ICD screen tubes, each screen tube is treated as a flow control unit to control the production of liquid. The filling layer between the flow control screen and the wellbore annulus plays a role in axial sealing and preventing water leakage for water control.
Technical advantages:
No need to determine the location of the water outlet point;
Both new and old wells are applicable;
Both casing wells and open hole wells are used;
Each sieve tube has a sealing effect, which can achieve infinite level water control;
Infinite level isolation in the horizontal section, minimum flow control unit for water control;
L can play a role in filling and sand control.
