Function
The multiple activation by-pass valve is a set of short circuit that can be opened and closed for many times. It is generally installed in special drilling tool assemblies such as directional drilling, speed raising, logging while drilling, etc. It can open and close the bypass hole in time for special operations according to downhole working conditions, enhance the applicability of special drilling tool assemblies, improve production efficienand reduce well control risks.
Advantages
1) lt can realize special operations such as plugging without tripping out, shorten drilling cycle and reduce welcontrol risk:
2) The bypass valve automatically closes when the pump stops, reducing the possible U-tube effect or wellcontrol problems,
3) it is not limited by downhole tools, instruments and bit waterholes. and can realize larae displacement welflushing;
4!) Effectively remove cuttings bed in directional and horizontal well sections,
5) 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 shallbe 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 andswitch ball set. A switch ball group comprises an activation ball, two closing balls and a locking ball. Theactivation ball and locking bal are made of a new type of engineering plastics, and the closed ball is made otstandard bearing steel ball.
