摘　　要：随着非常规油气资源重要性的日益显现,这些非常规储层的评价成为业界面临的挑战,而传统的测井方法由于未知骨架的成份,所以对于复杂岩性而言,确定储层骨架参数极其不准确。现提出应用一种新的地球化学元素测井结合其它资料识别非常规储层岩性骨架的方法,经过解谱得到地层元素干重,进而求得其氧化物,从而识别其岩性。结果表明,地球化学元素测井对复杂成分灰岩储层、致密砂岩气储层和火成岩储层岩性识别以及骨架参数确定方面有明显的优势。With the increasing importance of unconventional oil and gas resources, the evaluation on the unconventional reservoir is a chal- lenge faced by the petroleum industry. Due to the unknown composition of matrixes, the logs parameters by traditional logging methods usu- ally cause inaccurate interpretation results. Combined with other logging information, a new logging method by application of geochemical el- ements was proposed to identify the matrix and lithology of unconventional reservoir. And the lithology is identified by the element oxides calculated from dry weight of formation element from graph analysis. The results show that the geochemical element logging displays an obvi- ous advantage in lithology identification and determination of the skeleton parameters of the complex composition of limestone reservoir, tight sandstone gas reservoirs and igneous reservoirs
