在鑽進工作中,什么时候提鑽最有利,这是目前地質部各隊普遍忽视的一个問题。有些隊虽在现行的班作業計划中,有一个半小时進尺曲线圖,在确定提钻时刻上起到了一定的作用。但由于这个曲线还不够完善,因而在确定提钻问题上还存在着一定的盲目性。现将用合理的钻程提高钻进效率的有关问题叙述如下: In the drilling work, when to drill the most favorable, which is currently the Department of Geology Department generally overlooked a problem. Although some teams have a one-and-a-half-hour footage plot in the current classwork plan, they have played a certain role in determining the timing of jacking. However, since this curve is not perfect enough, there is still some blindness in determining the problem of pulling holes. The issues related to improving drilling efficiency with a reasonable drill program are described below:
