Integral Spiral/Straight Blade Stabilizer.
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. Features: Reduces vibration Decreases drill pipe whirl Reduces well bore tortuosity The Non-Magnetic Stabilizers will centralize the drill string in all conditions, but are specifically engineered to be used in applications requiring magnetic isolation, making them ideal for directional drilling. Features:The non-magnetic steel properties allow MWD tools to operate without interfering with the accuracy of their directional measurements. The non-magnetic stabilizers are compatible with other standard drill string components and are available in both spiral and straight blade configurations. ¡ñIntegral Spiral Blade Stabilizer Stabilizer is one useful tool for drilling operation. MDX offers a wide variety of near bit stabilizers and string stabilizers according to API SPEC 7. All drilling stabilizers are integral style, also can be highly customized as per customers requirements. Integral Spiral Blade Stabilizer is designed to control hole deviation, prevent differential sticking and minimize dogleg severity and thus provide optimum drill bit's performance. It is divided into Integral 3-Spiral Blade Stabilizer, Integral 4-Spiral Blade Stabilizer. The unitized construction features three spiraled ribs designed to minimize downhole torque, reduce damage to the hole wall and ensure maximum fluid circulation. The IBS is well suited for use in most formations from soft and sticky to hard and abrasive. It is available in both bottom-hole and string designs, providing the flexibility to run it anywhere in the BHA.The Integral Blade Stabilizers manufactured from high-strength alloy steel as a single piece tool. Fully heat treated, their strength, hardness and impact strength are attained to standard. There are four kinds of abrasive resistant materials on the working surface of stabilizer: insert tungsten carbide buttons,insert diamond compound body,low temperature welding tungsten carbide pieces,hard facing electrode on the surface and so on.
