Abstract

A significant sandstone reservoir at the present burial depths greater than 3 500 m, located in the Wenchang Formation of HZ-A area in Huizhou depression, Pearl River Mouth Basin, was deposited in the braided fluvial delta environment. Based on comprehensive analysis of thin sections, cathodeluminescence microscope, X-ray diffractometor, scanning electronic microscope, physical property analysis and so on, the characteristic of reservoir, diagenesis and pore evolution in Wenchang Formation of HZ-A area were studied in detail. Authors have established a quantitative model for their pore evolution during the geodynamic history by using quantitative analysis method. The results show that the sandstones are mostly lithic sandstone characterized by low compositional and textural maturity. The reservoir has mainly experienced the compaction, early cementation, dissolution and late cementation in sequence and has been at the middle diagenetic A2 stage. Dissolution was the only diagenetic factor resulting in the improvement of reservoir physical property. Both mechanical compaction and late cementation mainly resulted in pore destruction. The original porosity of the reservoir was 35.1% and had the loss of 15.4% by mechanical compaction and the loss of 3.4% due to early cementation. Acid dissolution increased the porosity of 7.2%. The pores were occluded by late clay minerals and carbonate cements, resulting in the reduction of 11.5%. Consequently, the low-porosity and low-permeability reservoir is formed.
