Technical features:
A single size ball with a large sliding sleeve diameter; The inner diameter is close to the inner diameter of the casing; Facilitating the use of other tools;
There is no time for pumping, stopping the pump, waiting for the continuous oil pipe to run down, or drilling and grinding; By reducing homework time, it is expected to reduce homework costs by 40%;
Suitable for ultra long and high displacement horizontal wells; Eliminate the risk of inadequate pumping in large displacement wells and eliminate damage to casing caused by drilling and grinding;
L can be used for external sealing segmentation process, and can also be connected to casing for segmented fracturing after cementing.
