Abstract

Abstract:

In the past two years，industrial gas flow was obtained in Xu3 Member calcarenaceous sandstones segment of Xujiahe
Formation of Northeast Sichuan Area，which suggests that reservoir in Xujiahe Formation of study area shall be hydrocarbon
and has the geological conditions ofhigh yield. We made analysis of the type of reservoir lithology，reservoir space，physical
property，electric property and so on. The researches show that lithology type of reservoir includes calcarenaceous sandstone，
often accompanied by microfracture. It has various pore space which mainly consists of residual original intergranular pore，
secondary dissolution pores and cracks. The reservoir shows low porosity and low permeability. Reservoir resistivity is high，
because of high carbonate content. The reservoir log response shows low GR，AC and CNL and high resistivity decreases under
the background of high resistance. The calcarenaceous sandstone reservoir in the study area is controlled by the comprehensive
factors such as favorable sedimentary microfacies，dissolution，structural fracture and reservoir thickness. The most advantageous
reservoir sedimentary micro-facies is braided river，underwater distributary channel；dissolution during the diagenetic
process and fracture under the influence of multiphase tectonic fissures greatly improves the permeability of reservoir；the certain
thickness reservoir improves the connectivity of fracture system，and is advantageous to oil and gas migration and gather
accumulation.

Key words: Northeast Sichuan Area, calcarenaceous sandstone, Xujiahe Formation, microfracture, secondary solution pores,
braided river
