2026-05-25 “Diagenesis and Differential Reservoir Effect of Mixed Sediments in Saline Lacustrine of the Permian Lucaogou Formation in the Northern Slope of Jimsar Sag, Junggar Basin”Mixed Sedimentary Rock Data Table doi:10.57760/sciencedb.cjxb.00019 en A total of 340 samples were analyzed by X-ray diffraction, which was completed in the State Key Laboratory of Southwest Petroleum University. The experimental instrument was SmartLab SE X-ray diffractometer (Table 1). Particle size analysis is an image particle size analysis method, which was completed in the State Key Laboratory of Southwest Petroleum University. The experimental instrument is Leica DM2700, and the data statistics software is polarization software (2010 version) (Table 2). Select 6 key samples for cathodoluminescence and electron probe composition analysis based on their diagenesis. The electronic probe composition analysis and cathodoluminescence observation were completed at the Key Laboratory of Natural Gas, Southwest Petroleum University. Among them, cathodoluminescence. The electron probe experimental instrument is JXA-8230 electron probe analyzer, with an acceleration voltage of 15.0 kV, a beam current of 10 nA, and a beam diameter of 11.1mm. The mass fractions of 9 common elements in carbonate minerals are measured using spectroscopy. Spectral analysis has an accuracy of over 1% (mass fraction of primary elements>5%) and 5% (mass fraction of secondary elements between 1% and 5%), and can automatically identify elements with mass fractions above 0.1%. The detection limit is 0.01% (Table 3). In addition, 98 plunger samples were selected for hole permeability analysis, and the experiment was completed in the State Key Laboratory of Southwest Petroleum University. The experimental instrument was CMS-300 hole permeability analyzer, and the analytical method was GB/T 29172-2012 (Table 4).  Jimsar Sag; Permian; Lucaogou Formation; Mixed sediments; Diagenesis; Reservoir chen jun lang Liu Xiaohong Yu Haiyue Kang Jilun Lin Tong Feng Mingyou Tang Hongming Shang Junxin Tian Chenguo PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
