Current Situation of Drilling Mud Cooling Technology and Research on a New Type of Drilling Mud Cooling System

摘要:

在中高温地热钻井、深部油气钻井、冻土带钻井及天然气水合物钻井中，钻井泥浆冷却技术是钻井工艺中的关键技术之一。适当的井内循环泥浆温度是钻井作业安全快速进行的保证，根据泥浆冷却冷源获得方式的不同，将钻井泥浆冷却技术分为高温泥浆冷却技术和低温泥浆冷却技术。分别论述了在中高温地热钻井和深部油气钻井中采用的高温泥浆冷却技术，以及在冻土带和天然气水合物钻井中采用的低温泥浆冷却技术，并针对我国在低温泥浆冷却技术领域的现状，介绍了一种新型钻井泥浆冷却系统。

Abstract:

Mud cooling is a key technology of middle-high temperature geothermal drilling, deep oil & gas drilling, permafrost drilling and gas hydrate drilling operation. Proper temperature of circulation drilling mud is the guarantee for safe and fast drilling operation. According to the feature of cooling sources, drilling mud cooling technology would be divided into hightemperature cooling technology and low mud cooling technology. The paper respectively discussed high-temperature drilling mud cooling technology in the middle-high temperature geothermal drilling and the deep oil & gas drilling; and the low temperature drilling mud cooling technology in permafrost drilling operation and gas hydrate drilling operation. In view of the current situation of low temperature drilling mud cooling technology, a new type of drilling mud cooling system was developed.
