泡沫钻井液具有的降低压持效应、加快机械钻速等优点,广泛用于低压易漏地层的钻井领域,但是现场存在泡沫堆积问题难以解决。利用负压和热辐射原理消泡装置,可以提高消泡速率,解决此类问题。本文重点介绍了该装置的系统结构以及自动控制系统的工作原理。 The foam drilling fluid has the advantages of reducing the pressure holding effect, accelerating the penetration rate of the machine, and is widely used in the field of drilling with low-pressure leaky formations. However, the problem of foam accumulation in the field is difficult to be solved. The use of negative pressure and heat radiation defoaming device, you can increase the defoaming rate, to solve such problems. This article focuses on the system structure of the device and the working principle of the automatic control system.
