Integral Blade Stabilizer

Integral blade stabilizer is an important tool in the drilling engineering to control the well deviation. It can stabilize the drilling tools in the drilling process of oil, gas and geological exploration. It can increase the bit life, drilling speed and well bore quality. There are two kinds of integral stabilizers: spiral integral blade stabilizer and straight integral blade stabilizer.
Hardfacing type: HF1000, HF2000, HF3000, HF4000

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...

Iron Roughneck DESCRIPTION   DETAIL The iron roughneck consists of the main forceps and the knobs, which are able to buckle / shackle the string diameter range from 2-7 / 8 "to 10" and the full operation of the buckle / shackle is integrated in one Pneumatic control box, press the button once to complete all operations, while the pneumatic control box can be installed in a safe place to achieve remote control. SCOTON as one of the leading iron roughneck manufacturers in China, also use high-quality iron roughneck parts to ensure each iron roughneck for sale is qualified. The Miniscope which is used to position the iron roughneck, is a compact, lightweight device that is driven by a hydraulic cylinder to achieve the force in both directions - to stretch and push To promote the iron drill to the wellhead buckle, after the end of the iron drill back to the rest position. T-120 Iron Roughneck The new T-120 Iron Roughneck from SCOTON produce with ma...
