Abstract To identify the factors controlling high-quality deep shale gas reservoirs and exploration development potential of Lower Paleozoic marine in Sichuan Basin, sedimentary environment was comprehensively analysed using core thin sections, scanning electron microscopy, gamma ray spectrometry logging, elemental logging data. In addition, geological conditions accumulation effect tectonic processes on preservation are discussed based experimental data mineral composition analysis,...
The exploration and development of deep marine shale gas has made significant breakthroughs, but factors influencing contents are elusive, quantitative prediction methods content needs to be refined urgently. In this study, the Longmaxi Formation in Luzhou area was taken as an example, vitrinite reflectance analysis, kerogen microscopy experiment, TOC mineral composition measurement, isothermal adsorption physical property analysis argon ion polishing scanning electron experiment were...
Fractures have significantly impacted the preservation, enrichment, and productivity of shale gas in Longmaxi Formation complex structural area southern Sichuan Basin. Based on outcrop, core, imaging logging, inclusion analysis, acoustic emission experiments, burial thermal evolution history data, formation stage, preservation conditions fractures were comprehensively studied. Shear are main features tectonic origin characterized by small widths, wide spacing, high filling degrees. The can...
Due to the tightness of shale, its fluid microflow mechanism has always been a hot topic research. The lattice Boltzmann method become an effective way study this in gradual improvement over past few decades. However, current research not yet provided unified analysis various microscale effects and heterogeneity porous media. By introducing regularization equations, correcting local Knudsen numbers, modifying boundary conditions, combining with generalization processing effects, article...
The Lower Silurian Longmaxi Formation in the southern Sichuan Basin is composed of a series dark carbonaceous shales deposited hydrostatic shelf reduction environment. In this study, ratio uranium to thorium (U/Th), total organic carbon (TOC), and biological silicon content (SiBio) were selected as characteristic parameters precisely analyze sedimentary environment its impact on reservoir quality. results show that Weiyuan area Early period experienced two transgression-regression cycles,...
The southern Sichuan Basin is the core area of China’s efficient development deep shale gas (burial depth greater than 3,500 m). Reservoir geological characteristics determine whether can be preserved, enriched, and produced. Taking Long 1 sub-member Wufeng Formation Upper Ordovician Longmaxi Lower Silurian in East Weiyuan–North Rongchang as an example, we used core, logging, production test, other data, combining X-ray diffraction analysis, LECO Total Organic Carbon (TOC)-S optical...

<title>Abstract</title> This study addresses gaps in research on the pore structures of deep, organic-rich marine shales, focusing lower Silurian Longmaxi Formation Sichuan's Luzhou Block, using wells L1 and L2. Employing techniques like organic geochemistry, mineral composition analysis, CO<sub>2</sub> N<sub>2</sub> adsorption-desorption, high-pressure mercury intrusion, FIB-SEM, NMR, identifies pyrobitumen as main contributor, accounting for approximately 59.95%-62.00% pores. It documents...
Increasing the resolution of seismic data has long been a major topic in exploration. Due to effect high-frequency noises, traditional methods could only improve limitedly. To end this, this paper newly proposed high-resolution processing method based on well–seismic combination after summarizing research status high resolution. Synthetic record and seismogram are similar effective signals but dissimilar noises. Their regular noises irregular. And they adjacent frequency. Based these...
This study proposed an improved method f to calculate Q factor, which is derived from a pre-stack inverse by former researchers based on generalized S transform. Meanwhile, this specifies theoretical initial wavelet and calculates cumulative factors, then finds inter-laminar factors using the relationship between offset (QVO) Dix formula. Since frequency spectrum of each horizon can be extracted continuously 2-D time-frequency spectrum, defined as "CONTINUOUS" spectral ratio slope (CSRS)...
Permeability, the ability of a porous material to allow fluids pass it, is key factor determine whether gas and oil field productive. Current efforts predict permeability prefer laboratory analysis empirical models. Laboratory costly limited by sample collection, while model only works when reservoir determined be or fractured in advance. Taking medical imaging technology as reference, this study firstly proposed method for estimating based on Darcy's law, effectively avoiding difficulty...
This study demonstrates an application of a well-logging based seismic resolution enhancement method implemented toseveral3D surveys. Technically, on the basis building relationship between synthetic records generated from logging and record, is enhanced by using neural network algorithm. The feasibility applicability this have been verified theoretical simulation test real data tests. Hereon, applied in different work areas for further verification, including horizon interpretation,...
The complex bedding textures of shale have been confirmed to cause acoustic attenuation during propagation so that the sonic logging tool can only receive second wave or subsequent signals instead first wave, which shall result in an abnormal increase value developing area. From point petrophysics, real AC should satisfy sum product each formation component's volume percentage and its theoretical response value. Comparing measured with derived from cores (ACtheory), when are developed, there...
