旋挖钻机钻进入岩判定与地层识别方法
Formation identification method based on embedding judgment of rotary drilling rig
摘要
Abstract
In order to improve the efficiency of the construction and increase the identification accuracy of bearing layer, the direct measurement parameters and the derivation parameters of rotary drilling rig were recorded and analyzed using real time monitoring system for drilling process. The drilling parameters and the physical and mechanical stratum parameters reveal inherent characteristics and statistical properties. The formation identification system relating geological conditions with the parameters of drilling was proposed. The results show that the drilling parameters definitely change with the variation of stratigraphic structure. The rotary rig shows different dynamic characteristics according to different embedded depths. All kinds of strata can be reflected in general based on specific energy to evaluate the bearing capacity. Compared with the survey results, the formation identification method based on drilling parameters of rotary drilling rig has been proved to be effective.关键词
