Drilling hydraulics pdf4/6/2023 ![]() ![]() ![]() Field examples are solved in the discussion. The method for constructing the work graph from which nozzle sizes are selected is presented. This method may be used to maximize any one of the three. ![]() predetermined friction loss in the system. Graphs are presented for obtaining circulation rates for various pump liners, stroke length, and strokes Graphs 1A and 1B).Ī nomograph of annular velocities-vs-circulation rates for various hole and drillpipe size combinations is presented (Graph 2). Drilling hydraulics are based on maximum bit horsepower, hydraulic impact, or jet velocity and are all dependent on a predetermined friction loss in the system. The derivation of the maximum horsepower, impact force, and jet velocity equations are presented in an excellent paper by Kendall and presented in an excellent paper by Kendall and Goins.Ĭonditions that are necessary for maximizing any of these three parameters are listed without derivations in Table 1. Examples will be worked in this paper which will maximize hydraulic impact and bit horsepower. Recent trends have been to maximize bit hydraulic impact. The purpose of this study is to investigate the fundamental relationship between thixotropy and drilling hydraulics.

In another word, obtained results of drag and hydraulic showed the consistency of trajectory. The subject of rotary drilling hydraulics has received a great deal of attention in the literature. ![]()
