Genesis of Densification of Low-Permeability Tight Sandstone Reservoirs: A Case Study of Lower Jurassic Badaowan Formation in Mobei-Mosuowan Swell, Junggar Basin

doi:10.7657/XJPG20210104

Abstract

Abstract:

Based on the rock thin section, casting thin section and X-ray diffraction whole-rock mineral analyses, and the data of scanning electron microscopy and reservoir physical properties, the petrologic, physical and diagenetic characteristics of the tight reservoirs in the lower Jurassic Badaowan formation of the Mobei-Mosuowan swell in Junggar basin were studied, and the genesis of reservoir densification was analyzed. The results show that the reservoirs are characterized by low compositional maturity, low content of interstitial matter and high content of plastic debris, and that the reservoirs have experienced strong compaction, weak cementation and general dissolution. Strong compaction is the most important factor on the reservoir densification, which is caused by strong compaction from acid diagenetic fluid in coal measures and strong static rock compaction from the high content of plastic debris in the Badaowan formation. Due to the low plastic debri content, the medium-coarse sandstone and coarse sandstone have strong fluid compaction effect and weak static rock compaction effect, therefore the medium-coarse and coarse sandstone reservoirs in Badaowan formation have good physical properties and are favorable for oil and gas accumulation.

Key words: Junggar basin, Mobei swell, Mosuowan swell, Jurassic, Badaowan formation, tight sandstone reservoir, compaction
