  • In order to dissect the characteristics of underwater distributary channel and discuss its significance for the formation of lithological traps,the sedimentary microfacies characteristics of an underwater distributary channel were analyzed by multi-parameter analysis. It is proposed that underwater distributary channel microfacies sandbodies which develop in different paleogeomorphological units are of great significance to the formation of lithological traps because of their different physical properties. The results show that two paleogeomorphological units are present in an ancient low rise and an ancient trench in the second section of the Sangonghe Formation in the study area:a non-rotat-ing distributary channel was developed in the ancient trench,and a rotating distributary channel developed on the sides of the low rise. The physical properties of the normal cyclic underwater distributary channel sandbody gradually deteriorated from bottom to top,and lateral blockages formed at the sides of the reverse cyclic distributary channel reservoir,which was beneficial to the formation of lithological traps. On this basis,a lithological trap model was es-tablished and applied for the positioning of a pre-exploration well in the oilfield, and achieved good results.

Abstract: In order to dissect the characteristics of underwater distributary channel and discuss its significance for the formation of lithological traps,the sedimentary microfacies characteristics of an underwater distributary channel were analyzed by multi-parameter analysis. It is proposed that underwater distributary channel microfacies sandbodies which develop in different paleogeomorphological units are of great significance to the formation of lithological traps because of their different physical properties. The results show that two paleogeomorphological units are present in an ancient low rise and an ancient trench in the second section of the Sangonghe Formation in the study area:a non-rotat-ing distributary channel was developed in the ancient trench,and a rotating distributary channel developed on the sides of the low rise. The physical properties of the normal cyclic underwater distributary channel sandbody gradually deteriorated from bottom to top,and lateral blockages formed at the sides of the reverse cyclic distributary channel reservoir,which was beneficial to the formation of lithological traps. On this basis,a lithological trap model was es-tablished and applied for the positioning of a pre-exploration well in the oilfield, and achieved good results.
