Abstract
This article describes issues relating to monitoring vibrations affecting the processing equipment. Especially, the problem of negative influence from the increased vibration background in well drilling, where the issue is the most acute, is being described. The urgency of creating methods to monitor vibration condition, due to which it becomes possible to design reliable and efficient structures with the required characteristics and purpose, is shown. Particular attention is paid to passive methods for monitoring torsional vibrations of pipe columns. In this case, the developed method for monitoring the vibration condition of torsional vibrations is presented, and its effectiveness is shown. In addition, a new device for monitoring torsional vibrations to the developed method, which is distinguished by its simplicity as well as high potential of reliability and efficiency, is shown.
Highlights
The vibrations of machinery and equipment of the oil and gas complex are one of the main negative factors leading to decrease in fault-free time and increase in repair and operating costs
The problem is acute in drilling, since vibrations of the drive unit – drill string – drilling bit system are inevitable, since the drilling is a dynamic process of destruction of the rock that being worked [1]
Well drilling has come to widespread use of complex and expensive technologies, the vibration effect on equipment arising during the drilling process leads to even greater economic losses
Summary
The vibrations of machinery and equipment of the oil and gas complex are one of the main negative factors leading to decrease in fault-free time and increase in repair and operating costs. Well drilling has come to widespread use of complex and expensive technologies, the vibration effect on equipment arising during the drilling process leads to even greater economic losses. The development of effective methods for monitoring vibration condition is an urgent task [3]. 2. The relevance of the development of vibration condition monitoring method One of the ways to reduce the cost of drilling operations is to increase the penetration of a well, which can be achieved by changing the operating parameters: the DS rotary speed or the axial stress on the bit.
