APPLICATION OF SAND CONTROL TECHNOLOGY FILLED ONLY ONE TIME WITH PACK AND HIGH PRESSURE

To be filled in or out of the tube is the develop tendency of the sand control technology with gravel filled, so filled only one time with pack and high pressure dose. The principles, tool structure, and construction procedure were introduced, and the design method of the main parameters, such as discharge capacity, pressure were expounded. It was introduced that the technology has been used in old well with single or more beds, new wells, inclined wells and wells with siltstone. It has more advantages such as shorter construction period, longer sand control efficiency period, stranger applicability, and higher fluid production intensity. The higher integrate benefit of it has been obtained.
