Study on formation mechanism of low resistivity gas bearing reservoir in Anyue-Hechuan area
Online published: 2011-06-20
Reservoir in Anyue-Hechuan area is characterized by low porosity and low permeability. The complex micropore system and largr water film density lead to its high bound water saturation, which makes lots of highly mineralized formation brines formed particularly developed conductive network, forming the low resistivity characteristics. The reservoir lithology combining with physical property and water quality are applied to conduct the related calculation and experimental analysis, and explore the contributing factors of low resistivity gas bearing reservoir in Anyue-Hechuan area. The result shows that the factors of lowresistivity gas bearing reservoir in Anyue-Hechuan area include grain grade size, highly mineralized formation brines and high bound water saturation.
