Abstract

Abstract: The southern slope of Huimin is a new exploration area for replacement of oil and gas resources. Based on data from development wells and prospecting wells drilled in this area, the hydrocarbon generation condition of Linnan sub-sag, the slope structure and reservoir-cap rock features are analyzed. It is believed that this paleo-uplift zone is provided with matured condition for hydrocarbon accumulation. The target zones for prospecting include three reservoir-cap rock assemblages of Cenozoic dominated by exploring heavy oil-gas pool and secondary gas pool and three reservoir-cap rock assemblages of Mesozoic and Paleozoic dominated by exploring coalformed gas. Lithology traps and structural traps are mainly found in Mesozoic and Cenozoic strata, while fault block-buried hill traps are primarily in Paleozoic strata.

Key words: Huimin, enriched hydrocarbon accumulation, trap, complex reservoir
