Abstract:

The Jishan sand body is a set of petroclastic sedimentary system in north-west of Huimin depression during upper or middle sedimentary period of 3rd Shahejian Formation.Through analysis of the characteristics of petrology,sedimentology,seismism and well log, the authors think it is a set of delta-channel-slumping turbidity fan sedimentary as a result of composite genesis. It can be divided into four parasequence sets.Restricted by faults and paleotopography, four sets of sand bodies are different in distribution range and area.They show characteristics of regressive deposition.Because of large sedimentary area, high-grade reservoir ,the Jishan sand body took extreme condition of pool forming.Fitting with faults and paleotopography,it can form tectonic reservoirs,lithology reservoirs and tectonic-lithology reservoirs.
