PREFACE
At the basis of majority technological operations of oil and gas well drillinglie hydro-aeromechanical processes. Currently, drilling is practically impossible without circulation of drilling and plugging fluids. Actually, removal of cutting from the well, application of turbo drills and jet bits, lowering of casing strings and casing cementing, control of circulation loss and reservoir fluid showings, investigation of lost circulations, and production horizon zones do not make a complete list of operations that go hand i hand with hydro-aeromechanical processes. Hydro-aeromechanics in drilling is a special branch in oil technology in which flows of circulating and plugging fluids, skeleton, and bed fluid in well drilling are considered and described. Designing, planning, optimization, and realization of drilling schemes would have been impossible without data made available by this branch. A rapid rise in the number and depth of wells in the last few years has attracted enhanced attention to hydro-aeromechanical problems in drilling. With scientists joining forces, some problems were successfully solved. On the basis of these developments, the hydro-aeromechanical theory underlying the main technological operations of well drilling has been systematically presented in this book. The text is based on lectures given at the Moscow State Gubkin University of Oil and Gas.
