Koomey unit ( BOP control system ) for surface BOP stacks is very important equipment which controls BOP stacks and gate valves controlled by hydraulic pressure especially in drilling and workover operations. It is necessary to accurately operate and maintain the hydraulic control system. The hydraulic control system manufactured by SCOTON can be divided into 3 types: Directly manually operated FK series hydraulic control system The hydraulic control system not fitted with a driller's console is applicable to drilling or workover operations and is simple and portable. The hydraulic control system can be fitted with a mechanical anti-lifting device (see the operation manual for the anti-lifting device). Pneumatic liquid type FKQ hydraulic control system This hydraulic control system is fitted with a driller's console or an auxiliary driller's console (optional). Alarm type and non-alarm type driller's console and auxiliary driller's console can be installe...

Wireline BOP

The wireline BOP is used for sealing the wellhead to prevent well blowout accidents is logging operation when there are accidents and there are cables in the well. The  wireline BOP has simple structure, convenient application and maintenance, small volume, light weight, high pressure bearing, hydraulic remote control and simple and reliable operation. The BOP is mainly composed of main casing, and ram assembly piston, hydraulic cylinder, lead screw, end cap, hand wheel and other spare parts, which are moving in the main casing in opposite direction. When the well needs to be sealed, the hydraulic control and grease injection pressure control system is pressurized to push the piston, thereby leading the two ram bodies to move towards the center of the well bore, and well sealing can be achieved through the associative action of the front rubber sealing element and the top sealing rubber. The ram can be locked on the shut-in position through clockwise rotating the locking hand...
