Abstract

Abstract

The Xixiangchi Formation is a potential target for oil and gas exploration in the Sichuan basin, yet detailed descriptions of its reservoir space diagenetic mineral filling characteristics and hydrocarbon charging features are scarce. Based on 24 core samples, in this study it dissects the reservoir spaces and hydrocarbon charging characteristics of the Cambrian Xixiangchi Formation in the central area of the Sichuan basin through detailed thin-section microscopic observations, cathodoluminescence testing, microscopic hydrocarbon trace detection, and systematic fluid inclusion analysis. The results indicate that the Xixiangchi Formation primarily comprises dissolution pores (vugs), interparticle (intercrystalline) pores, and fractures as its reservoir spaces, which are filled with multiple types and stages of diagenetic minerals such as dolomite, calcite, and quartz, as well as bitumen. Microscopic traces such as bitumen filled in reservoir spaces, bitumen or bitumen-bearing inclusions and natural gas inclusions trapped in diagenetic minerals record multiple stages of hydrocarbon activities and the process of adjustment and modification. The overall hydrocarbon charging characteristics show that ancient oil reservoirs were formed in the early Indosinian period (Early Triassic). Large-scale oil cracking into gas occurred from the late Indosinian to early Yanshanian periods (Late Triassic to Early-Middle Jurassic), forming the first stage of natural gas charging. Residual oil cracking into gas occurred in the middle Yanshanian period (Late Jurassic to Early Cretaceous), forming the second stage of natural gas charging. Adjustment and modification took place in the late Yanshanian period (Middle-Late Cretaceous), forming the third stage of natural gas charging.
