China Multiple Activation Bypass Valve (MCBV) Manufacturer and Supplier

Multiple Activation Bypass Valve (MCBV)

Multiple activation bypass valve is a set of short sub which can be opened and closed for many times. It is generally installed in special BHA such as directional, speed-up,LWD and so on. It can open and close the bypass hole in time for special operation according to the requirements of downhole conditions, so as to enhance the applicability of special BHA, improve production efficiency and reduce well control risk.

Features

1. It can realize special operations such as plugging without pulling out of BHA, shorten drilling cycle and reduce well control risk;
2. When the pump is stopped, the bypass valve will close automatically to reduce the possible U-tube effect or well control problems;
3. It is not limited by downhole tools, instruments and bit bore, and can realize large displacement well flushing;
4. It remove cuttings bedin directional and horizontal well section effectively;
5. It can protect of downhole instruments and power drilling tools effectively;
6. It can realize multiple underground open and close operations.

Structure

The multiple activation bypass valve is mainly composed of bypass sub, ball basket sub and switch ball group. As shown in Figure 1.A switch ball group comprises an active ball, two closed balls and a locking ball. The active ball and locking ball are made of a new type of engineering plastics, and the closing ball is made of standard bearing steel ball.

ADVANTAGES

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