Replaceable Sleeve Stabilizer

Replaceable sleeve stabilizer consists of mandrel and sleeve. The function is the same as spiral integral blade stabilizer. It can suit to different hole size and increase working life by changing the different size sleeve. The sleeve is threaded on the mandrel, so the sleeve can be fasten to the mandrel tightly and changed easily.

PDC bit

图片
The full name of the PDC bit is Polycrystalline Diamond Compact bit. PDC bit is a drilling tool commonly used in the geological drilling industry. In fact, its evolution is evolved from the diamond. According to the bit body material classification ⒈ Matrix Body PDC Drill Bit Matrix body PDC bit is a t ype of cutting drill that welds a diamond composite sheet by brazing on the drill body. The carcass bit is sintered with tungsten carbide powder and brazed to the tungsten carbide carcass with artificial polycrystalline diamond composite sheet and cut with natural diamond. ⒉ Steel Body PDC Bit Steel body PDC bit is nickel, chromium, molybdenum alloy machining forming. After the heat treatment in the drill body drilling, the artificial polycrystalline diamond composite sheet into the (tight fit) drill body, with cylindrical tungsten carbide path.

Dissolvable Frac Ball

Dissolvable Frac Ball DESCRIPTION SCOTON's SDF Dissolvable Frac Ball is a metallic dissolvable frac ball designed to provide zone-successive isolation for frac plugs, frac sleeves and static isolation subs. Its high shear strength allows it to maintain integrity and isolation during high pressure fracturing and the Wraith Frac Ball dissolves at controllable and predictable rates to allow production from all treated zones. Cast and machined from an aluminum base, the SDF Frac Ball's high shear strength is excellently suited to High Pressure, High Temperature and Horizontal/Extended Reach applications. The SDF Frac Ball only requires exposure to water at temperatures above 100° F to begin dissolving, however faster dissolve rates may be achieved. SCOTON has developed an empirically proven equation which accurately and reliably predicts the dissolve rate of SDF Frac Ball in water based on its (compound and physical) properties and specific bottom hole temperatu...

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...
