现有的固控系统,流程冗繁,系统庞大,花费昂贵,而且固相颗粒的重复破碎对钻井作业危害极大。针对这种弊端,国外研制出一批新型固控设备,在总体上完全改变了传统的布局。江汉机械研究所高级工程师潘玉兰在《国内外钻井液固控设备的现状与发展》中,详述了MAX过滤系统、流体调节器等地面固控装置之后,介绍了一种井下固控短节。这种短节实质上是接在钻头上的一个或两个水力旋流器。所需能量由钻井泵供给。钻进时,钻井液沿着短节的槽孔流至旋流导向器,以
The existing solid-control system has many complicated processes, huge system and expensive cost, and the repeated crushing of solid-phase particles is very harmful to the drilling operation. In response to this drawback, a number of new fixed-control equipment developed abroad, in the overall completely changed the traditional layout. Pan Yulan, a senior engineer at Jianghan Machinery Research Institute, described the status and development of drilling fluid solid-control equipment both at home and abroad. After details of the MAX solid-state control devices such as MAX filtration system and fluid regulator, . This short section is essentially one or two hydrocyclones attached to the drill bit. The required energy is supplied by the drilling pump. When drilling, the drilling fluid flows along the short slot to the swirl guide
