The screen-type sand screen can be used for both external and internal sand control with filtration and moderate filling. It features multi-layer composite filtration layers, providing high reliability in sand control, with outstanding performance advantages in various aspects. The sand control effect is effective, and it has a long service life.
It has a large flow area, which can effectively improve the oil production index and reduce formation pressure loss;
The pores are evenly distributed, with high permeability and strong anti-blocking capability, resulting in a blockage cycle that is 2 to 3 times longer than that of ordinary screens, and it is easy to backwash.
High reliability and effective sand control.
It can be used in oil, water, and gas wells; for cold production and thermal production wells; as well as in vertical, inclined, directional, and horizontal wells. This technology has been successfully applied in over 1 million meters both domestically and internationally, with a wide range of clients, including Shengli Oilfield, Henan Oilfield, Jidong Oilfield, Xinjiang Oilfield, and Dagang Oilfield. Internationally, it has been successfully implemented in regions such as Sudan, Colombia, and Kazakhstan, achieving excellent results in sand control and production enhancement.
