钻进过程的强化,很大程度上取决于所用冲洗液种类和性质。就当今钻探设备,依靠增加钻杆柱转速来大幅度提高钻速是可能的。但是,随着转速增加设备的磨损和能量消耗就要增长。因此,必须使用保证最佳钻进条件的高润滑性的冲洗液。在苏联南乌克兰地质局生产地质联合体的工作区域,地质条件复杂。孔深达200m的铁矿床剖面特别复杂。含矿岩层内强烈破碎,剖面上经常遇到亲水的滑石化页岩夹层。在这种地层
The reinforcement of the drilling process depends very much on the type and nature of the rinse solution used. With today’s drilling rigs, it is possible to dramatically increase the rate of penetration by increasing the speed of the drill string. However, as the speed increases, wear and energy consumption of the device increases. Therefore, you must use the best drilling conditions to ensure the use of high lubricity rinse. In the working area where the Soviet Union Southern Ukraine Geological Bureau produces geological complexes, the geological conditions are complex. The profile of an iron deposit with a hole depth of 200m is particularly complicated. The ore-bearing strata are strongly crushed and the hydrophilic talc-interbed shale intercalations are often encountered in the sections. In this formation
