摘要

Combined with oil and gas transport and accumulation, structure-lithology evolution history, and with geochemistry and synthesizing geology methods, this paper studies the oil and gas discharge history of Puguang large scale gas field and the main controlling factors of oil accumulation. The natural gas in Puguang gas field is mainly coal-derived gas and oil-racked gas. The main hydrocarbon is Upper Permian coal mudstone and Lower Silurian mud shale with organic material. Puguang gas field has gone through discharge and adjustment 3 times, and it has favorable palaeostructure location, high quality dredge and effectively conserving conditions.
