摘要

Guided by the idea of a “superposition-controlled reservoir”, the technical route of geologic analysis, seismic data interpretation, analogue modelling and basin digital modelling, geometry, kinematics, and dynamics are adopted in this paper to carry out systematic research on the deformation characteristics and evolution processes of different reformation types and their control on oil and gas accumulation and the depletion of deep marine strata in the Palaeozoic. In this paper, four stages of tectonic evolution and five types of intracontinental transformation since the Late Triassic are established, the time frame of transformation deformation is constructed, dynamic hydrocarbon accumulation characteristics and models under the control of different types of superimposed transformation are established, and favourable hydrocarbon accumulation zones and targets are proposed.
