Multiple Activation BY-Pass Valve

Advantages

It can realize special operations such as plugging without tripping out, shorten drilling cycle and reduce well control risk;

The bypass valve automatically closes when the pump stops, reducing the possible U-tube effect or well control problems;

It is not limited by downhole tools, instruments and bit waterholes, and can realize large displacement well flushing;

Effectively remove cuttings bed in directional and horizontal well sections;

Multiple downhole switching operations can be realized, and our products can be switched 6 times.

Application fields

1) High concentration and large particle plugging materials and cement squeezing plugging construction shall be carried out without tripping out;

2) Special construction of pumping other corrosive liquids;

3) High displacement well flushing in directional wells, horizontal wells and highly deviated wells;

4) Clean casing and BOP stack;

Basic structure

The multiple activation bypass valve is mainly composed of three parts: by-pass nipple, ball blue nipple and switch ball set. A switch ball group comprises an activation ball, two closing balls and a locking ball. The activation ball and locking ball are made of a new type of engineering plastics, and the closed ball is made of standard bearing steel ball.
