The article explores the main types of equipment vibrations that occur during drilling, their causes, signs of the manifestations and complications caused by their action. It also describes recommended measures for reducing their negative influence and ways of improving efficiency. For many years scientists have studied only one type of vibratory movement of the drill string – axial. This can be partly explained by the fact that until recently the vast majority of the oil wells were drilled by roller bits, which are virtually unaffected by torsion vibrations and it is very difficult to fix transverse vibrations without special equipment. Besides the level of development of down hole recording equipment often was not allowed to do it. A qualitative leap in the speed of wells construction, caused by the early use of diamond drill bits of cutting-chipping action, brought its own difficulties. So a significant increase in the required torque led to increased stress on the layout of BHA and intense manifestation of other types of vibrations. It prompted the development of the field of damping devices and recording equipment. In addition to the axial a set of damping devices were developed. They worked in tangential and transverse directions. But the different nature of occurrence and different characteristics of these types of oscillations doesn’t allow creating a versatile design, equally well working in a variety of applications. This article presents some operational characteristic, depending on the type of dynamic effects, which are required for the successful design, selection and application of vibration isolation devices in the drill string.
