Abstract

The average porosity and average permeability of clastic reservoir of Lower Cretaceous in Tanzhuang Sag are respectively 6.1% and 10.5 mD based on the data of cores, thin section, and scanning electron microscope, which means that the reservoir belongs to low porosity and low permeability reservoir. Porosity and permeability decrease from Shangshui Formation to Bacun Formation with depth getting deeper except in Ba 1 well. The reservoir properties of the Lower Cretaceous are mainly influenced by depositional conditions, diagenesis and tectonization. Low textural and compositional maturity, strong compaction and cementation and weak dissolution are composed of the essential and significant factors for the low porosity and low permeability, while fractures caused by tectonization mostly are filled by minerals as a result of little improvement of the reservoir properties.

Key words： Monte-Carlo method; OOIP; Chi-square test; sensitivity analysis
