Deflector

Our deflecting tools have two types: anchor type deflector and hydraulic setting slip type deflector. hydraulic setting slip type deflector supply accurate orientation solid seat sealing advantages etc.
When reservoir area casing seriously damaged or reservoir sand buried or collapsed, the well can't production, in order to use the upper casing, reduce the cost of drilling, can make window cutting sidetracking on the upper casing above oil layer, to form a new hole for drilling.
Internal window sidetracking is a crucial method when drill a deviated well with seriously damaged bottom casing, to use the upper casing, make the well build up production capacity.
Window sidetracking tools mainly including deflector and window milling taper.

Koomey Unit (BOP Control System)

图片
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

Milling And Fishing Tools DESCRIPTION Scoton provide diversized tools in oilfield milling and fishing to meet different customers' requirements. Multi-purpose Casing Scraper (Ultra - clean casing scraper ) Multi-purpose casing scraper is a new type casing scraper, it can worked as nonrotating fixed type casing scraper, and also can worked as a rotating type casing scraper . Besides normal cleaning operation, it should stop running in the drill string when stuck, then should connect the washover tools, and applying some pull force to shear the pin, then shift to rotating mode, then proceed releasing stuck operation, like providing a torque, pushing, circulation and jarring until recover the normal situation, then continue to run in drill string.
