The First Ultra-long Horizontal Well in Shengli Oilfield Completed Sand Control Construction

Shenghai 201B-P2, the first ultra-long horizontal section casing horizontal well in Shengli Oilfield offshore oilfield, has completed sand control construction. In view of the problems of large formation leakage and easy sand jam in the pipe column, Shengli Oilfield Offshore Production Plant has made preparations in terms of technology, equipment, materials, etc. to ensure high-quality and efficient construction. This is the first time that Shengli Oilfield has implemented a two-stage filling sand control construction in a casing perforated horizontal well offshore. The sand c

ontrol well section of this construction is 500 meters, and the maximum well inclination is 91 degrees. Both data set the highest record of the same type of sand control technology in China.
