Drilling stabilizer is an important tool to control hole deviation in petroleum and gas exploration drilling process.

钻具稳定器是石油、天然气及地质勘探钻井工程中，防止井斜变化的重要工具。其稳定器的形式可分为钻柱型，井底型。稳定器种类分为：整体螺旋稳定器、整体直棱稳定器、可换套扶正器、滚轮铰孔器、变径稳定器、浮阀稳定器、球形稳定器、非旋转扶正器。HF3000，HF4000型稳定器。

Drilling stabilizer is an important tool to control hole deviation in petroleum and gas exploration drilling process. The types of it can be divided into drill string type and near bit type. At present,we developed HF3000 and HF4000 type stabilizer, which are widely used in international drilling operation. Drill collars, when used without stabilizers, tend to buckle and cause unwanted deviation. A typical bottom hole assembly (BHA) will include one or two stabilizers placed in the drill string to increase stiffness. Sometimes additional stabilizers are added to the drill string to further increase BHA rigidity to ensure that well bore deviation is minimized.

Stabilizers also prevent differential sticking of the drill string by stabilizing the BHA and keeping drill collars and drill pipe away from the borehole wall. This reduces vibration, drill pipe whirl, and well bore tortuosity; moreover, the stabilization maintains drilling trajectory whether drilling straight, horizontal, or directional wells.

Options for Stabilization

Our factory downhole offers stabilizers in straight and spiral orientation with two material options:

Alloy Steel Stabilizers non-Magnetic Stabilizers

The Integral Blade alloy Steel Stabilizer is a product of exact manufacturing and is engineered to stabilize your drill string in the most challenging drilling conditions. The rib surface shall be hard faced with HF4000 (Insert tungsten carbide buttons on the surface ) OR HF 3000( low temperature welding tungsten carbide pieces) .

When drilling through hard formations, the required weight on bit to drill the well bore exerts tremendous side loads on the blades of the stabilizer. The Integral Blade Stabilizer's one-piece construction ensures you have the reliability and durability to drill with confidence. MDX Downhole Integral Blade Stabilizers are available in both Straight and Spiral Blade designs.
