Api 7 1 Drilling Tool Downhole Mud Motor Suppliers and Manufacturers

Description High-grade barium sulfate specially processed use as a drilling fluid weighting additive. BARITE meets the API Specification 13A, Section 2 requirement for a drilling fluid BARITE Recommended Use Primarily for mud rotary drilling, barite increases mud density while maintaining low solids to help control formation pressures Advantages 1. High specific gravity; raises drilling fluid density with minimum solids 2. Controls formation pressure, stabilizes the borehole 3. Cost-effective, non-toxic, and chemically inert Properties 4. Specific Gravity: 4.2 (minimum) 5. Moisture Content: Less than 1% 6. Bulk Density: 150 lbs/ft3 7. Mineral Content: 94% barium sulfate Mixing and application Add BARITE through high shear mixer or jet hopper so that entire circulating volume is at uniform weight. To control artesian flow at surface, keep the hole full at all times with weighted mud. Starting with 100 gallons of mud at a weight of 9 lbs/gal, 134 lbs of BARITE will raise the weight to 10 lbs/gal and increase the volume to 104 gallons. Packaging 1500 kgs Jumbo bags, one bag per pallet. All are of F.I.B.C. Class, SINGLE TRIP, all weather ( 04 PF Inner Bag & 05 PP Outer Bag )

All products will be made according to API and related international standards as per customers' requirements. Integral blade stabilizer is an important tool in 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

Drilling Jar Type BZ is full mechanical type drilling jar and releasing stuck tool. The Drilling Jar integrates the upward jarring with the downward jarring so that it can release from the tight pull or the sticking etc. during drilling. The load(jarring force)scope of the upward jarring and the downward jarring is so wide that it can be adjusted in the maintenance station or in the well site according to the requirement. The special flexible joint can reduce the flexural stress of the drilling jar body efficiently. So it is the first selected drilling jar for vertical well, deep sell, directional well and complicated well operations.

Down-hole motor/mud motor is a positive-displacement motor(pdm), the high drilling fluid enters into the high fluid power converted into mechanical energy, and the rotor drives the principal shaft and bit rotating.

1. ADVANTAGES OF DOWNHOLE MOTOR Increased rate of penetration. Better hole deviation control. Reduction in drill string failure rate. Reduction in wear and tear of the swivel, Kelly, and rotary drives. Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor. 2. CONSTITUTION Downhole motors differ in size and performance characteristics, but they share the same basic components as follows (Fig.1) : Crossover Sub Safety Catch Sub Power Section Coupling Assembly Bearing Assembly

4145h api 7-1 drill collars are made of modified aisi 4145h chromium molybdenum alloy steel. These drill collar bars are full-length heat treated and water quenched to obtain astm a-370 mechanical properties. Full mechanical and chemical mill test certifications are supplied with all drill collars. These mill test certifications guarantee a hardness range of 285 to 341 bhn and an impact value of 40 ft.-lbs. At room temperature one inch below the surface. To ensure close tolerance bores, all drill collar bars are trepanned then drifted to api specifications. Bar surface finish is “as rolled” which is original mill finish. Connections: All connections are precision-machined to api specifications. Api relief groove pin and bore back box stress relief are available on request. Thread roots are cold-worked to offer a greater resistance to fatigue. All connections are phosphated to minimize galling during makeup and applied with thread storage compound. Thread protectors are installed to ensure adequate joint protection during shipment.

Kelly is the drive part of whole drill stem, it has two types, square kelly and hexagonal kelly and all of them are manufactured comfort to API Spec7-1 and SY/T6509-2000 criterion. Our Square& Hexagonal kelly are made from AISI 4145H modified alloy bars that are quenched and tempered full length. After such heat treatment, its brinell hardness can reach 285-341. Kelly's end, drive cross-section and joint are all processed and tested comform to API criterion. Features and Benefits Manufactured from AISI4145H-modified, fully heat-treated alloy steel with a Brinell hardness range of 285-341BHN and a minimum average Charpy impact value of 40ft-Ibs; Ends and drive section,IDs and connections machined and inspected to API specification; Ultrasonic inspection is performed on all section; Shipped in a protective steel -cased scabbard; When ordering please specify: Kelly type (Square or hexagonal) Nominal size and overall length Upper and lower connection Technical specification and parameters

Lowest price API 7-1 non magnetic spiral drill collar Product Description Drill Collar is the basic component in the BHA which provide weight on the bit for dirlling and keeps the drill string in tension.Drill collar is manufactured from AISI 4145H modified quenched and tempered steel and is heat treatment along its entire length for uniform toughness and durability. Srict netallurgical test are performed pre specifications to ensure that the heat treatment produces consisitent and maxium hardness through the depth of the bar. Feartures and benefits: 1. hardness rannge of 285 to 341 BHN and a charpy impact value of 40ft/lbs are guaranteed for evenly distributed 16 points in any cross sections at room temperature 2.Connections ar phosphate coated afther machinning to protect the threads from corrosive elements and to prevent galling upon initial make -up Thread roots are cold rolled on API and H0-90 connections 3.Pressed steel thread protectors are supplied fo all drill collar that are equipped with standard connections
