Abstract:

The cold weather in the north of China in winter brings many problems to the on-site compound logging. It is particularly important to strengthen the cold protection and maintenance of the equipments, which is the premise to ensure the normal operation of the on-site comprehensive mud logging unit in winter and to ensure its stable working performance and measurement accuracy. The sensors,signal wires, auxiliary equipments of comprehensive mud logging unit and field bus of different types of comprehensive mud logging unit are similar. In the open-air environment in winter,the construction equipment and facilities easily get frost damage, deformation and signal distortion. In terms of the climate characteristics of the north in winter, measures against cold and frost are formulated.The best and feasible cold protection and maintenance plan are chosen. For the northern comprehensive mud logging team in winter, it is a fair suggestion to make sure that prevention is prior to treatment.
