Abstract

With the deepening of the unconventional reservoir exploration, formation lithology evaluation is becoming more and more difficult, because in addition to the common minerals such as quartz, calcite, illite, some special minerals like pyrite, gypsum, dolomite, ankerite can also been seen. However, conventional well logging curves are difficult to identify these complex minerals. Spectroscopy tool, such as Element Capture Spectroscopy tool (ECS) can measure the capture spectrums of the main elements in formation such as silicon, calcium, iron, sulfur, and then the absolute contents of different minerals can be derived. This provides a new train of thought for unconventional reservoir lithology evaluation. But if feldspar, chlorite, dolomite, pyrite minerals are rich in the formation, default outputs from ECS will differ from core analysis results greatly. Based on a certain amount of core samples, this study analyzed the absolute contents of elements and minerals, and established the suitable complex mineral reconstruction model for the target formation in K block, and laid a solid foundation for tight sand mineral evaluation and reservoir evaluation.
