摘　　要：目前广泛推广使用的欠平衡钻井工艺的施工方法已对录井作业产生了直接或间接的、不同程度的影响。为此,从分析欠平衡钻井的工艺入手,研究了其对录井作业的各种影响因素,特别是对工程录井、常规地质录井和气测录井的影响。结果认为,欠平衡钻井工艺对录井作业的影响是非常明显的,但这些影响可通过调整录取方法、改变录取位置、改变解释方法而得以剔除,部分影响还需要进一步寻求合适的途径来消除。从长远看,发展适应欠平衡钻井工艺的录井设备和软件体系是非常必要的;同时加快录井工艺研究、适应钻井工艺发展步伐,也是现代综合录井工作长期努力的方向。Wide application of underbalanced drilling techniques has directly or indirectly influenced logging operation to some extent. Beginning with an analysis of the underbalanced drilling technologies, this paper studies its various influences on logging, especially engineering logging, conventional geologic logging and mud logging. It is believed that underbalanced drilling technology has significant influences on logging operation, most of which can be eliminated through adjusting logging methods, changing logging position, and improving interpretation methods, but some still cannot be eliminated at present and need further studies. In the long term, it is necessary to develop logging equipment and software adapted to the underbalanced drilling technology. Moreover, speeding up research of logging technology and keeping up with the development of drilling technology are also the trend of long term development of modern compound logging.
