The invention relates to the technical field of offshore exploration, in particular to a logging device of an offshore drilling platform, which comprises a cable winch, a cable arrangement mechanism, a guide wheel set and a logging instrument, the logging instrument comprises a power supply pup joint, a storage pup joint and a logging pup joint, and the logging instrument is connected with the cable winch through a logging cable; the logging cable extends out of the cable winch, then is steered by the guide wheel set and then extends downwards, the logging instrument ascends and descends through forward/reverse operation of the cable winch, tight winding of the logging cable on a winding drum can be effectively guaranteed through the tight cable pressing assembly and the tensioning detection assembly, and therefore the logging instrument can be prevented from being damaged. Therefore, the stable operation of the logging system can be effectively ensured, and the control of the underground operation depth of the logging device can be effectively improved.
本发明涉及海上勘探技术领域,具体为一种海上钻井平台的测井装置,括电缆绞车、排缆机构、导向轮组和测井仪器,所述测井仪器包括电源短节、存储短节和测井短节,所述测井仪器通过测井电缆与电缆绞车连接,所述测井电缆从所述电缆绞车延伸出后经过导向轮组的转向后向下延伸,通过所述电缆绞车的正向/反向运作实现测井仪器的升降,通过紧密压缆组件和张紧检测组件,能够有效的保证测井电缆在卷筒上的紧密缠绕,进而能够有效的保证测井系统的稳定运行,同时能够有效的提高测井装置的井下作业深度的控制。
