AbstractCast thin section observation, scanning electron microscopy (SEM), high‐pressure mercury injection (HPMI), and nuclear magnetic resonance (NMR) were used to examine the microstructure of tight carbonate reservoirs in the Lower Jurassic Da'anzhai Member, the central Sichuan Basin. The pore space in the Da'anzhai Member is classified into 2 types

Abstract The distribution pattern of oil and gas in the western part of central Sichuan Basin is complicated, there are many different views on the sources of natural gas, which restrict further exploration and deployment of oilfields. Therefore, by analyzing geochemical characteristics and quantitative calculation of natural gas in study area ...

AbstractBased on core observation, cast and fluorescent thin sections, FESEM and ESEM, coquina in Da'anzhai Member of Jurassic in Sichuan Basin were examined systematically. Together with production data and logging evaluation, a method for lacustrine coquina evaluation based on geological theory was established up.

Abstract Lacustrine shale reservoirs with interbedded organic-rich shales and thinly layered tight shell limestones are mainly developed in the Da'anzhai Member of the Lower Jurassic Ziliujing Formation in the Fuling area. These reservoirs generally have low porosities and permeabilities.

Abstract Although numerous progresses have been achieved in characterizing marine shales, studies that are associated with lacustrine shales are limited. To study lacustrine shales, samples were collected from the Jurassic Da'anzhai Member in the central Sichuan Basin of China, and their mineralogical, reservoir, OM, and paleoenvironmental ...

The prediction of thin limestone reservoir is an international problem in seismic exploration. The limestone reservoir of Da'anzhai member in the eastern Sichuan Basin features super tightness, strong heterogeneity and thin layers. Based on post-stack deterministic Constrained Sparse Spike Inversion, this paper applies geostatistical inversion to ...

Abstract Lacustrine limestone always develops multiple matrices, and the matrices characteristics and effects on oil production have not been carried out effectively. Although the lacustrine limestone of the Jurassic Da'anzhai Member in the central Sichuan Basin is considered supertight, it still produces relatively large amounts of oil.

Abstract Compared with the studies of nanoscale pores in shale, coal, and tight sandstone, studies associated with lacustrine tight carbonate nanoscale pores and their control mechanisms, particularly quantitative studies combining reservoir evaluation and geochemistry, remain scarce.

Abstract The lacustrine shale in the Jurassic Da'anzhai Member is considered as an excellent source rock in the central Sichuan Basin. However, geochemical studies of lacustrine organic matter (OM) accumulation factors and mechanisms are scarce. This study investigated the variations in total organic carbon (TOC), major elements, trace elements (TEs),

ABSTRACT The Early Jurassic Da'anzhai Member of the Ziliujing Formation, located in the Sichuan Basin, represents a key stratigraphic unit for unconventional hydrocarbon exploration due to its organic‐rich facies and favourable depositional conditions. This study employs an integrated approach, combining lithofacies analysis, sequence
