Abstract

Abstract:

According to the concept of "petroleum accumulation system",in combination with source rocks,source-reservoir relationship,reservoir characteristics and accumulation mechanism,we recognized two Mesozoic petroleum accumulation systems in the southern Ordos Basin,i.e.near-source system and far-source system.The near-source accumulation system is dominated by lithologic traps,and features in short migration distance,abnormal pressure as major driving force of migration,and implicit carrier system.Hydrocarbon accumulation in the near-source system is mainly controlled by high-quality source rocks and reservoirs as well as favorable structural setting,and the pattern of hydrocarbon accumulation can be described as "near-source and facies-control".The far-source system is dominated structural traps and structural-lithologic traps,and is characterized by long migration distance,buoyancy as the major driving force of migration and source rock-rooted faults containing the major carrier system.Hydrocarbon accumulation in the far-source system is mainly controlled by source rock-rooted faults,local structures and high-quality sandstone reservoirs,and the pattern of oil accumulation can be described as "far-source and fault-control".The source rock-reservoir relationship in the near-source system has a "sandwich-like" structure.The synchronism of peak hydrocarbon generation with hydrocarbon accumulation provides favorable conditions for widespread and large-scale hydrocarbon charging and accumulation near source rocks.The near-source systems are the priority of future exploration,and the top-ranking play fairways in the CH₉-CH₈-CH₇ near-source systems are the important exploration targets for large- and medium-sized oil and gas fields.

Key words: play fairway, near-source accumulation, far-source accumulation, petroleum accumulation system, Mesozoic, Ordos Basin
