DIAGENESIS OF FUYU OIL LAYER AND PREDICTION OF THE DEVELOPED SECONDARY PORES IN YUMIN REGION
摘要
Abstract
Fuyu oil layer is the main oil & gas-bearing series of strata in Yumin area, which is characterized by typical low porosity and low permeability, so the types and intensity of the diagenesis become the key influencing factors of the physical properties of the reservoir. By the studies of the relative data on the core observation, thin section of casting, and the others, the studied area has experienced the following diageneses: mechanical compaction, cementation, metasomatism, dissolution, etc. Among them, the former two belong to destructive actions and result in the dominant factors of the poorer physical properties of the deep clastic reservoir; and meteoric water leaching, solution and other constructive diageneses promote the development of the secondary pores and then greatly improve the physical properties of the reservoir; the metasomatism has a little effect on the properties. On the basis of the studies of these diageneses, the many impacting factors of the secondary pores are comprehensively considered , and the stacked and grading method of the main controlling factors are adopted to horizontally predict the development of the secondary pores in Fuyu oil layer of Yumin area, and furthermore to provide the guide for the pe-troleum explorations in both the area and the deep strata of Songliao Basin.关键词
