摘要
In Huanghua Depression Dongying Formation, with fine accumulation properties, is the important exploration intervals?? in the research area. There is intimate relationship between the time and space distribution and material resources for the dispersed system of sand. Material resource system analysis is one key work for hydrocarbon exploration. So, Q-mode clustering procedure used in statistics is applied to the analysis of the change of heavy minerals content in the research area, and then division is made based on different mineral assemblage.
