| Abstract: | For the conventional seismic sections in L block, H Basin, seismic facies analysis is made, and seven types of seismic facies are recognized according to internal structure and external geometrical configuration of seismic reflections. Based on the seismic facies model, depositional system model and drilling data of non marine faulted basin, seismic facies can be converted into sedimentary facies, and the distribution of Lower Cretaceous depositional systems can be predicted. Therefore it is pointed out that the main association of source, reservoir and seal is located in upper section of A sequence. |
