欠平衡钻井录井方法探讨

根据欠平衡钻井技术的特点,结合目前国内录井设备和技术现状,分析了欠平衡钻井技术中常规录井技术的局限性,针对欠平衡钻井工艺的特点,探讨了通过对岩屑分析、气体组分分析、气体采样、地层压力检测、流量检测、定量荧光检测及火焰观察等录井手段对地层含油、气情况进行识别和评价的方法,提出了相应的设备配套技术和录井方法,并给出了应用实例。

Probe into Under-balanced Drilling-Logging Method

According to the features of under-balanced drilling method,and connecting with the present situation of logging equipment and technology in China,this paper analyzes the limitations of conventional logging technology in under-balanced drilling technologies,and in the light of the features of under-balanced drilling technologies,probes into the method for identifying and evaluating the hydrocarbon reservoir through cuttings analysis,gas composition analysis,gas sampling,formation pressure detection,flow detection,quantitative fluorescence detection,and flame observation,etc.,and puts forward corresponding equipment supporting technologies and logging methods with application examples.
