[Abstract]:Well stem string is the backbone and central nervous system of oil drilling and production. In petroleum and natural gas engineering, the mechanics of oil and gas stem string is an important applied basic science. Firstly, this paper introduces the related monographs on the mechanics of oil and gas rod string, and studies the methods of the mechanics of oil and gas rod string and clarifies some basic concepts. The basic mechanics principle of oil and gas rod string, the movement state of oil and gas rod string, the basic equation of oil and gas rod string dynamics, the stability of oil and gas rod string, the steady tension torque of oil and gas rod string are introduced in detail. Three dimensional mechanical analysis, drill string dynamics, casing string mechanics analysis, test string mechanics analysis, fracturing injection steam injection string mechanics analysis, rod pump pumping system diagnosis and parameter optimization and energy saving, gas production string vibration, Shock vibration of pipe string, mechanical analysis of expansion sieve (sleeve) pipe, mechanical analysis of pipe string with water barrier, propagation of vibration wave signal in string, wear, corrosion and erosion of string, The progress and controversy of the prediction of residual strength and fatigue strength of pipe string; The key research direction of the string mechanics of oil and gas wells is prospected.
