Summary

Fluid mechanics plays an inestimable role in the process of oil and gas exploitation and transportation, the oil and gas well fluid mechanics is the most important framework of various oil and gas drilling and production techniques. The development of oil and gas well fluid mechanics plays an indispensable role in the oil and gas industry, and it is also crucial for the exploration and development of geothermal, combustible ice, coalbed methane and solid mineral resources. This Special Issue aims to present and disseminate the most recent advances related to the theories, methods, technologies, and materials in oil and gas well engineering fluid mechanics. Topics of interest for this publication include, but are not limited to:

(1) All aspects of the fluid mechanics and dynamics related to the oil and gas well engineering.

(2) The fluid mechanics and dynamics of well drilling, cementing, completion, testing, logging and reservoir reconstruction technologies in conventional oil and gas, deep or deep-water oil and gas, and unconventional oil and gas wells, as well as geothermal resources, etc.

(3) The application of new materials (graphene, etc.) in oil and gas well fluid.

(4) The fluid mechanics and dynamics of carbon-reducing technologies (CCS, CCUS, etc.) in oil and gas well engineering in the context of carbon-neutral and carbon-peak technologies.

(5) The fluid mechanics and dynamics of developmental technologies of new energy resources (hydrogen energy, etc.).

(6) Oil and gas percolation mechanics, wellbore hydrodynamics, etc.

    Jet Characteristics and Optimization of a Cavitation Nozzle for Hydraulic Fracturing Applications

    Yu Gao, Zhenqiang Xu, Kaixiang Shen
    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.1, pp. 179-192, 2024, DOI:10.32604/fdmp.2023.030499

    Abstract Hydraulic jetting is a form of fracturing that involves using a high-pressure jet of water to create fractures in the reservoir rock with a nozzle serving as the central component of the hydraulic sandblasting perforation tool. In this study, the flow behavior of the nozzle is simulated numerically in the framework of a SST k-ω turbulence model. The results show that the nozzle structure can significantly influence the jet performance and related cavitation effect. Through orthogonal experiments, the nozzle geometric parameters are optimized, and the following configuration is found accordingly: contraction angle 20°, contraction segment length 6 mm, cylindrical segment… More >

    Performance Analysis of a Profile Control Agent for Waste Drilling Fluid Treatment

    Xueyu Zhao
    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.7, pp. 1897-1905, 2023, DOI:10.32604/fdmp.2023.025247

    Abstract A method for the treatment of hazardous waste drilling fluids, potentially leading to environmental pollution, is considered. The waste drilling fluid is treated with an inorganic flocculant, an organic flocculant, and a pH regulator. The profile control agent consists of partially hydrolyzed polyacrylamide, formaldehyde, hexamethylenetetramine, resorcinol, phenol, and the treated waste drilling fluid itself. For a waste drilling fluid concentration of 2500 mg/L, the gelling time of the profile control agent is 25 h, and the gelling strength is 32,000 mPa.s. Compared with the profile control agent prepared by recirculated water under the same conditions, the present profile control agent displays better… More >

    Xin Huang, Yunpeng Jiang, Daowu Huang, Xianke He, Xianguo Zhang, Ping Guo
    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.6, pp. 1679-1691, 2023, DOI:10.32604/fdmp.2023.025312

    Abstract

    The seepage mechanism plays a crucial role in low-permeability gas reservoirs. Compared with conventional gas reservoirs, low-permeability sandstone gas reservoirs are characterized by low porosity, low permeability, strong heterogeneity, and high water saturation. Moreover, their percolation mechanisms are more complex. The present work describes a series of experiments conducted considering low-permeability sandstone cores under pressure-depletion conditions (from the Xihu Depression in the East China Sea Basin). It is shown that the threshold pressure gradient of a low-permeability gas reservoir in thick layers is positively correlated with water saturation and negatively correlated with permeability and porosity. The reservoir stress sensitivity is… More >
