Multiple Activation Bypass Valve (MCBV)

①Enhance the applicability of special drilling tool assemblies:

●Flexibility: The Multiple Activation Bypass Valve (MCBV) can be opened and closed multiple times, allowing special drilling tool assemblies to adapt to different downhole conditions and operating requirements.

●Compatibility: Designed to be compatible with various special drilling tools (such as directional drilling tools, logging instruments, etc.).

●Adaptability: It can be used in different types of wells (vertical wells, directional wells, horizontal wells), increasing the application scenarios of special drilling tool assemblies.

●Protection function: By controlling fluid flow, sensitive lower hole assembly (BHA) components are protected and extend their service life.

②Improve production efficiency:

●Reduce the number of trips: Many operations (such as plugging, wellbore cleaning) can be completed without drilling, significantly saving time.

●Quick response: Able to quickly adjust according to underground conditions, reducing waiting and decision-making time.

③Reduce well control risks:

●Automatic shut-off function: Automatically shuts down when the pump stops, preventing the U-tube effect and reducing the risk of well kick.

●Deal with problems in a timely manner: You can quickly respond to underground emergencies, such as timely plugging operations.

●Reduce tripping: The well control risks associated with tripping (such as well wall instability, well kicks, etc.) are reduced.

• High concentration and large particle plugging materials and squeezing cement plugging construction should be carried out without pulling out of BHA;
• Other special construction pumped in by corrosive liquid;
• Large displacement well flushing in directional well, horizontal well and highly deviated well;
• Remove metal burr in time during window opening and milling operation;
