Abstract

Abstract

The oilfield of Dongying Formation in Liaodong strike-slip fault transfer zone is characterized by large reserves and high abundance. However, the forming conditions of such reservoirs remain unclear. This study investigates the reservoir characteristics and comprehensive hydrocarbon accumulation conditions of Lyuda-A oilfield in Liaodong strike-slip zone of Liaodong Bay Depression by using drilling, 3D seismic, well logging and analytical test data. The results indicate that the oil-bearing series is the Paleogene Dongying Formation, belonging to an integrated high-quality Paleogene oilfield with the characteristics of concentrated oil-bearing intervals and high reserves abundance. The source rocks with large thickness, high abundance of organic matter, moderate maturity and favorable types provide sufficient material basis for the high-abundance oilfield. The faulted anticlinal trap controlled by the LZ1 strike-slip fault transfer zone, the thick reservoir formed by braided river delta developed in Dongying Formation and the efficient hydrocarbon migration pathway formed by induced fracture zones within the LZ1 strike-slip fault collectively constitute favorable accumulation conditions, ensuring the formation of high-abundance oilfield. The first-stage oil-gas charging in Dongying Formation is characterized by the late-stage rapid charging, which serves as a prerequisite for the formation of high-abundance oilfield.
