Report includes detailed drilling data for each core: pump(s) used, mud pumped, strokes, shear pins/pressure, bit size/rotation, weight on bit, top drive torque, rate of penetration, core jams, winch and wirelines, core catcher/shoe and barrel, and whether core orientation, drillover, formation temperature, tracers, liners were used.本报告包含每一块岩心（core）的详细钻井数据，涵盖所用泵组、泵送钻井液、冲程数、剪切销钉（shear pins）/工作压力（pressure）、钻头尺寸与转速、钻压（weight on bit）、顶驱扭矩（top drive torque）、机械钻速（rate of penetration）、岩心卡堵情况、绞车与钻井钢丝绳、岩心爪（core catcher）/岩心鞋（core shoe）与岩心筒（core barrel），以及是否采用了岩心定向（core orientation）技术、实施了复钻（drillover）作业、开展了地层温度（formation temperature）测量、投放了示踪剂（tracer）以及下入了衬管（liner）。
