Произведена оценка надежности элементов бурильной колонны с учетом вероятностных динамических переменных нагрузок. Показано, что оценить долговечности того или иного элемента колонны при вероятных колебаниях можно при определении среднеквадратичного напряжения последующего расчета эквивалентного в отношении усталостной прочности напряжения при чисто гармоничной нагрузки элементов бурильной колонны.

An assessment of the reliability of the elements of the drill string was carried out, taking into account the probability of dynamic variable loads. It is shown that the evaluation of a particular column element durability, when possible vibrations, can be done by determining the RMS subsequent calculation of the equivalent in relation to fatigue stress for purely harmonic load components of the drill string.

Рассмотрены колебания колонны бурильных труб с прямолинейной осью постоянного или переменного по длине сечения в условиях искревлением ее траектории. Показано, что амплитуда изгибаючих колебаний усиливается за счет центробежных сил при вращении колонны (роторное бурение).

Consider the drill string vibrations with linear axis AC or the length of sectional curvature in terms of its trajectory. It is shown that the amplitude of the bending vibrations is amplified by centrifugal force while rotating column (rotary drilling).

Many factors influence an efficiency of bottom-hole deepening process, among them - axial weight on drilling bit, bit speed, bottom-hole cleaning conditions and well geological conditions. However, existent methods of calculations of the drilling practices and strength calculation dо not consider the random character of the coefficients included in these dependences. The authors of the paper suggest the modеl of bottom hole-deepening, which takes into account dynamic parameters of drilling tools and еnаblе to forecast the drilling indexes with modification of the bottom-hole assembly and drilling practices for different types of drilling.

The analysis of frictional force, arising up at freeze liquidation under the action of the static loadings of drill column is conducted. The results of analysis testify that the task of liberation of the frozen column under the action of the static loading has stochastic character: calculations made with and without taking dry friction into account give high and low bounds of values of longitudinal force, here the exact value of longitudinal force, between these scopes, has а character of stochastic variable. Decreasing longitudinal force is possible by diminishing of coefficient f due to utilizing more active liquids for arranging baths, and also utilizing vibration and impact devices.

The analysis of dynamics of the frozen part of drill column utilizing vibration and impact devices is presented. Authors offer and ground the process of freeze liquidation of drill column by impact method, following the rules, derived from the theory of longitudinal impact and theory of friction. The conclusion is that vibration and impact liquidation of frozen part of column extends under the action of static tension, and processes, arising up in а column reduce the action of resistances or will implement anisotropic resistance force is drawn.

The theoretical analysis of process physics of the recovering of drill column sticking by impact devices is carried out. The fact that a significant energy volume under the recovering of drill column sticking by impact devices is wasted on oscillation of the column upper part instead of being directed to recovering process is ascertained.
