Abstract

Abstract

Yinggehai basin has peculiar sedimentary, tectonic and evolution model and is abundant in hydrocarbon resources. As the main and typical structure in diapir area, DF1-1 diapir develops a lot of faults and cracks, virtually related with gas accumulation. The process of formation, opening and closing of the faults in the top of the diapirs basically display the progression of the fluid/gas migration. When overpressure reached such a critical value with oil/gas accumulating and pressure increasing, faults open as the pathway of oil/gas migration. It will be more favorable if the fault cut the sandstone bodies or fractures in the overpressure area, which might result in oil/gas accumulating into these sandstone bodies (reservoirs). Therefore, faults are the fluid released pathway and sandstone bodies and fractures as reservoirs of oil/gas in DF1-1 diapir. The spatio temporal match of vertical source rocks, reservoir and seals, combined with fault system provided by diapirism, result in the formation of large DF1-1 gas field. The models about fault system and gas accumulation have also been presented and discussed.
