QF149-84-00 Ball Valve Type Fluid Loss Control Valve

Ruifeng QF ball valve type fluid loss control valve is a two-way formation isolation tool for open hole horizontal well and casing well. The combination effect of sealing steel ball and sealing pad can effectively isolate formation and wellbore, and has the function of preventing completion fluid leakage and avoiding reservoir pollution. The ball valve type fluid loss control valve is normally lowered into the well along with the lower completion string, providing a bidirectional barrier to seamlessly complete the lower end to the upper end without workover. It is suitable for all occasions with isolation requirements, such as intelligent completion, gravel packing, fracturing packing, independent sieve pipe completion, temporary abandonment, remedial workover, etc. This tool is a modular design, with two opening modes: mechanical repeated opening and remote opening, and the two opening modules can be used independently or in combination, and can be selected according to the actual well condition and requirements.
