钻进过程中 ,井下泥浆的漏失往往导致严重的钻井事故 ,从而延长钻井周期 ,增加钻井成本。为了有效地处理井漏 ,必须及时准确地测出漏层深度。文章介绍了一种在钻井中能随时自动测定漏层深度的方法。其设计电路简单 ,具有成本低、操作简便之优点 During drilling, the loss of downhole mud often leads to serious drilling accidents, which prolong the drilling cycle and increase the drilling cost. In order to effectively deal with the well, it is necessary to detect the depth of the drain in time. This article describes a method for automatically determining the depth of a leak during drilling. Its design circuit is simple, with low cost, easy operation
