Genetic Mechanism of Calcareous Interbeds in Shoreface Reservoirs and Implications for Hydrocarbon Accumulation: A Case Study of the Donghe Sandstone Reservoir in Hade Oilfield, Tarim Basin

Minerals
Calcareous interbeds are widely developed in marine clastic sequences, where laterally continuous, tight calcareous interbeds act as critical controls on the formation of lithologic traps and the distribution of oil.
