  • Patent number: 12163905
    Abstract: A method for determining a phase-state type and saturation of a fluid by an NMR technology includes putting a core to be measured to an NMR phase-state testing device, injecting a heavy water solution from both ends of a gripper at the same time until the core reaches the formation pressure, and stopping; scanning the core to obtain a two-dimensional NMR map, and determining whether the core contains a gas phase; reducing the temperature of the gripper, and collecting an oil phase volume, a gas phase volume and a water phase volume discharged from the core; purge the pipelines out with nitrogen, collecting a water phase volume and an oil phase volume in the pipelines; performing dry distillation on the core to obtain an oil phase volume and a water phase volume; and obtaining the saturations of various phases according to the fluid volumes of multiple phases in the core.

  • Patent number: 12031601
    Abstract: A core material for a shock insulation support, comprising, in parts by weight: steel shot of 150-300 parts, zirconia particles of 50-150 parts and rubber particles of 50-100 parts. Further provided are a shock insulation support comprising the core material, and a preparation method for the shock insulation support. The core material for a shock insulation support, and the shock insulation support dissipates earthquake energy by means of a dry friction energy dissipation mechanism, having high damping and excellent shock insulation performance.

  • Publication number: 20230366869
    Abstract: A Hydrophilic-Lipophilic Deviation theory-based method is provided to prepare representative degassed oil with equivalent minimum miscible pressure to live oil. The method can reduce the number of trial and error type experiments during the representative degassed oil preparation process by measuring the MMP and EACN for dead and live oil. The representative degassed oil formulation could be easily predicted after determining the required MMP and EACN values. The prepared oil can reflect the key mechanism of multiple contact miscible mechanism in the process of gas flooding more accurately. It allows experiments that are inconvenient to use live oil to consider the mechanism of multiple contact miscibility easily.
