This results in stretch and suggests that an ideal construction would be a continuous taper from top to bottom. Since such a shape is impractical, the use of tapered strings with sections of decreasing diameters is a common design practice. practice. The most basic property of any sucker rod string is its elastic behavior. P. 605

Drill rods with parallel threads These drill rods are manufactured to DCDMA and Swedish Metric standards. The rod tube is manufactured from high quality seamless carbon steel of high strength and uniformity. The male-threaded couplings are manufactured from heat-treated alloy steel for maximum toughness and wear resistance. The rods are suitable for rotary drilling applications.
General Introduction: Tapered drill equipment also provides a hexagonal chuck section to provide leverage for the rotation chuck bushing, which usually also has a forged collar to maintain the proper shank striking face position in the rock drill, and match a tapered bit at the socket end. Holes are typically drilled in 0.6 m increments to accommodate the air-leg feed length.
Reduce rod-tubing friction to extend rod-string and tubing life in deviated wells. With couplings only at the top and bottom of the rod string, COROD continuous rod provides an excellent alternative to conventional sucker rods by minimizing the potential for rod-string failures and costly interventions.
