摘　　要：PDC及高压喷射钻进等钻井新技术在港北潜山太原组的应用给该区块录井油气显示发现带来了巨大挑战,导致常规地质录井未能及时发现太原组油气藏及其岩性组合特征,为查明该地区地层的地质信息,并确定最适合该类油气发现的录井技术组合,以港北潜山油气层的两口探井为例,对其录井方法组合系列及应用效果进行总结,并对太原组岩性和含油性重新认识。最终确认,碳酸盐分析+薄片鉴定+XRD+XRF的录井技术组合对本地区复杂岩性及储集层的识别有良好的效果;气测+三维定量荧光+岩石热解分析的录井技术组合可以有效应对本地区地层含油性的判别。The application of new drilling techniques such as PDC and high-pressure jet drilling in Taiyuan formation of buried hills,northern Dagang brings great challenges to mud logging discovery of show of gas and oil in this block,which leads to the failure of conventional geological logging to find hydrocarbon reservoirs and their lithology combined characteristics in Taiyuan formation in time.In order to find out the geologic information of the strata in this area and determine the most suitable combination of mud logging techniques for this kind of oil and gas discovery,taking two exploration wells of hydrocarbon reservoirs in buried hill,northern Dagang as examples,the combination series and application effect of mud logging methods are summarized,and the lithology and petroliferous property of Taiyuan formation are re-recognized.Finally,it is confirmed that the combined mud logging technology of carbonate analysis+thin section analysis+XRD+XRF has a good effect on the identification of complex lithology and reservoir in this area,the combined mud logging technology of gas logging+three-dimensional quantitative fluorescence+rock pyrolysis analysis can effectively deal with the discrimination of formation petroliferous property in this area.
