BYJ70/35FQ no-killing operation device newly developed by bomco is a truck-mounted short-stroke dynamically sealed hydraulic device applying to the conditions that the depth of casing string is not deeper than 2,500m (oil tube), and the wellhead pressure is not more than 35MPa.

Technical Features

It may be used to coordinate workover rig or crane with the trip of oil string;

Integral installation and transportation design is adopted for convenient moving, small dismounting workload, and high working efficiency;

Fully manual hydraulic control system and dual-hydraulic-cylinder trip of oil string can achieve stepless regulation; during a trip, the string can be stopped and locked at any position by simple, safe and reliable operation; differential motion can be realized in case of a relatively light cylinder load to accelerate hoisting speed of cylinder and improve working efficiency;

The ring-type BOP adopts specially-made tubular rubber as the main sealing of no-killing operation device due to its small frictional resistance against string and availability for the passage of more string connectors;

The hydraulic system is controlled either remotely or locally, and can achieve emergency brake and well shut-in at any position, so the safety performance is very high.
