Multi-finger Caliper Logging Tool


multi-finger-caliper-logging-tools.jpg

Multi-finger caliper logging tool is the latest in technology and reliability. Based on sound engineering and machining, and combined with input from field experience, Multi-finger caliper logging tool is making itself known across the globe. The Multi-finger caliper logging tool provides a high resolution log along with the standard directional measurements expected from a modern caliper. It is completely Warrior Compatible, and does not require special keys and panels to operate. The tool has an integral digital telemetry cartridge which has proven to be extremely robust, operating easily on a wide range of electric lines. If you have a Warrior Data Acquisition System, you can begin logging right away.

Multi-finger Caliper Raw Log

The MFC sends an I.D. image (one sensor for each finger) plus additional curves: deviation and relative bearing for orientation and some control curves such as cablehead voltage and temperature. In addition there are some calculated curves derived from the image: Average I.D., Maximum I.D. and Minimum I.D.

Multi-finger Caliper Uses

The multi-finger caliper is used to detect casing deformation, bending, fracture, hole and inner wall corrosion by individual measuring fingers. The Displacement Sensors Without
Contact (Patented technology) are used to make high density measurement at limited diameter. The logging data is processed to get casing inner face imaging, circumferential profile imaging and cylindrical three dimensional imaging to clearly reflect casing damage. By using the relative azimuth, the effect of tool rotation can be adjusted as well.

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.
