API 7-1 drilling collar is one of the most important product of hexin oil drillings which mainly used to provide bit weight to drill so that drill pipe is in tension. Especially drill collar can keep drill bit centralized and hole track by large rigidity. GANG GONG brand drill collars are manufactured strictly from API Spec7-1 standard.
1.It is divided into drill string crossover and tubing Crossover. 2.Drill string Cross-over is divided into type A, type B and type C. Crossover subs are made from AISI41455H chrome molybdenum alloy steel, and the content of micro-element can be controlled availably. The surface of sub threads are phosphated or copperized. According to shapes and applications, crossover subs are divided into three types: Type a stands for the same diameter: one crossover sub has one size. Type b stands for reduce type: one crossover sub has two sizes. Type c for left hand thread type: the connection thread is left hand type. Use: it plays a role of connectivity and conversion in different specifications drilling tools. Characters: crossover subs are complied with SY5200-93 or API Spec7. All products must be ultrasonic nondestructive tested and the surface copper coated. Crossover subs of various types and lengths are available.
Traceability: Drill collar material and process traceability are maintained from receipt of the mill's certified raw material to completion of manufacturing. Serial numbers are die stamped on bar bodies. Rigid Inspection Procedures: We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar. Cold Rolling: Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation. Phosphate-coated or Copper Plating: All connections are phosphate-coated or copper plated to improve resistance to corrosion. Slip Groove, Elevator Groove and Size: Lake offers optional slip and elevator recesses to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with API spec 7-1 guidelines. Thread Protectors: Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.
Specifications about Mud Motor Downhole Motor Downhole motor is a kind of downhole dynamic drilling tool upon the power of drilling mud. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and outlet of the pump, to push the rotor into rotating, and to transmit the torque and speed onto the bit. The downhole motor property mainly depends upon its property parameters. 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. 1. Material: High manganese steel 2. Standard: API 3. Features: Big torque, high effective, wide flow rate range, running stable and long using time. 4. Specifications: Fit for 3 1/2"--17 1/2" well hole, including straight body, single- bent and

A mud cleaner is a combination of desanders and/or desilters mounted over a shaker with a fine mesh screen. A mud is fed to the inlet of the hydrocyclone (desander and/or desilter) to separate particles and the underflow passes to the fine screen mesh where in particles larger than barite are discarded and thrown away. In most drilling operations, a mud cleaner is installed in its mud systems. It is usually located in a mud tank in the same location as with the desilters.
