Digital Core Analysis on Water Sensitivity Mechanism and Pore Structure Evolution of Low-Clay Tight Conglomerate Open

Dunqing Liu, E Shi · 2025

This study investigates the mechanisms behind strong water sensitivity in some low-clay-mineral-content tight conglomerate reservoirs in China’s Mahu Sag. Using core-scale water sensitivity tests, mineral analysis, in situ micro-CT scannin…

Investigation on Imbibition Recovery Characteristics in Jimusar Shale Oil and White Mineral Oil by NMR Open

Dunqing Liu, Chao Jia, Keji Chen · 2025

Recovering oil by fracturing fluid imbibition has demonstrated significant potential for enhanced oil recovery (EOR) in tight oil reservoirs. White mineral oil (WMO), kerosene, or saturated alkanes with matched apparent viscosity have been…

Seepage Simulation of Conglomerate Reservoir Based on Digital Core: A Case Study of the Baikouquan Formation in Mahu Sag, Junggar Basin Open

Daiyan Zhang, Haisheng Hu, Dong Yan, Yingwei Wang, Dunqing Liu , et al. · 2023

Pore structure and flow characteristics are key factors affecting oil recovery rates in heterogeneous tight conglomerate reservoirs. Using micron computed tomography (CT) and modular automated processing system (MAPS) techniques, the pore …

Experimental Study on Characteristics and Mechanisms of Matrix Pressure Transmission Near the Fracture Surface During Post-Fracturing Shut-In in Tight Oil Reservoirs Open

Yanjun Zhang, Yi Zou, Yang Zhang, Luyu Wang, Dunqing Liu , et al. · 2022

Experimental Investigation on Organic Matter Orientation Characteristics of Terrestrial and Marine Shale in China Open

Dunqing Liu, Hongkui Ge, Yinhao Shen, Kui Zhang · 2021

As an essential component in shale, OM (organic matter) grains and their arrangements may play essential roles in affecting the anisotropy of the reservoir. However, OM grains are commonly treated as an evenly distributed isotropic medium …

Effects of gravel size and content on the mechanical properties of conglomerate Open

Jianbo Wang, Hongkui Ge, Jiantong Liu, Yinghao Shen, Zhenxin Zhang , et al. · 2021

There are many rock types on the earth, conglomerate is a common rock type in sedimentary rocks. In this study, uniaxial compression tests were conducted on the conglomerate containing gravels having diameters between 2–26 mm. conglomerate…

Experimental Study of Fracturing Fluid Retention in Rough Fractures Open

Yanjun Zhang, Hongkui Ge, Guangyu Liu, Yinghao Shen, Hao Chen , et al. · 2019

Multistage hydraulic fracturing is a key technology for developing tight reservoirs. Field data indicate that a small fraction of the injected water can be recovered during flowback. Fractures play an important role in the retention of fra…

Impact of fracturing liquid absorption on the production and water-block unlocking for shale gas reservoir Open

Yinghao Shen, Hongkui Ge, Xiuling Zhang, Long Chang, Dunqing Liu , et al. · 2018

A large amount of liquid is pumped into the shale gas reservoir during hydraulic fracturing, and the fluid flowback ratio is usually low. However, field experience showed that the liquids did not cause severe damage to shale gas reservoir.…

Quantitative investigation on the characteristics of ions transport into water in gas shale: Marine and continental shale as comparative study Open

Liu Yang, Xian Shi, Hongkui Ge, Dunqing Liu, Xiangmei Qu , et al. · 2017

Imbibition characteristic of shale gas formation and water-block removal capability Open

Yinghao Shen, Hongkui Ge, Shuai Su, Dunqing Liu, Zhihui Yang , et al. · 2017
