The “Multi-cycle Circulating Subs” is designed to via multiple pitches provide multiple water eye and loop switches’ joint .

The tool’s operation step is to use the pitching operation to switch the product on and off, with each pitch producing a specific switch position.

Application

The “Multi-cycle Circulating Subs” is designed to via multiple pitches provide multiple water eye and loop switches’ joint .

The tool’s operation step is to use the pitching operation to switch the product on and off, with each pitch producing a specific switch position.

Advantage:

1) Multi-cycle Circulating Subs is an ideal tool for use in large displacement Wells and horizontal Wells;

2) by standard, all loop heads have two large loop interfaces to minimize the risk of clogging;

3) Multi-cycle Circulating Subs is the only product that allows reverse circulation of total flow area among similar tools;

4) because of the unique design of Multi-cycle Circulating Subs, the flow interface is opened before the ball arrives at the collection joint, so as to prevent the ball from being arbitrarily cut into the collection basket;

5) the multi-cycle Circulating Subs can be opened in the predetermined position when entering the well;

6) the multi-cycle Circulating Subs can be switched at least 6 times, and the switching times can be increased if there are special requirements.

The multi-cycle Circulating Subs produced by our company is used well in Russia, Middle East and other countries.
