Drill collar has bars of solid steel that are drilled from one end to the other to provide a passage for pumping the drilling fluids through the collar. Collars that are available for drilling have an external diameter that is made of steel and can be slightly machine perfected for making sure of the roundedness.

Drill Collar Calculation Pressure Area Method Conclusion . The number of Drill Collars calculated by the Buoyancy Factor method is not enough to provide all the weight on the Drilling Bit WOB. Some of the WOB will be provided by the Heavy Weight Drill Pipe or Drill Pipe directly above the Drill Collars.

Drill collar has bars of solid steel that are drilled from one end to the other to provide a passage for pumping the drilling fluids through the collar. Collars that are available for drilling have an external diameter that is made of steel and can be slightly machine perfected for making sure of the roundedness. In the oil production process, line pipe is not the only tool needed for a successful wellbore. Among the materials used alongside line pipe are drill collars.. Drill collars are used to provide weight on the drill bit. They are tubular pieces of a drill string, which have thick walls made of steel or special kinds of alloy. The term drill collar derived from the short sub originally used to connect the bit to the drill pipe. Amodern drill collar is about 30 ft long, and the total length of the string of drill collars may range from about 100 to 700 ft or longer. The purpose of drill collars is to furnish weight to the bit. A drill bit is what actually cuts into the rock when drilling an oil or gas well. Located at the tip of the drillstring, below the drill collar and the drill pipe, the drill bit is a rotating apparatus that usually consists of two or three cones made up of the hardest of materials (usually steel, tungsten carbide, A Drill Collar is a tubular piece of a drill string which provides weight on the bit for the purpose of drilling. While drill pipes make up the majority length of drill strings, drill collars make only a small amount. They have thick walls machined from the solid bars of steel. The drill string is usually part are: drill, drill collars, drilling pipe, stabilizers, special connectors and Kelly. The basic role of the drill string are: (1)control the drill bit; (2) imposed WOB; (3) transmission of power; (4) transporting drilling fluid; (5) special operations: extrusion of cement, handling underground accidents. 1. n. [Well Completions] A threaded coupling used to join two lengths of pipe such as production tubing, casing or liner. The type of thread and style of collar varies with the specifications and manufacturer of the tubing.
