  • Publication number: 20200281156
    Abstract: The present invention is a pet cage having an upper cage member and a lower base member. The lower base member has at least two portions: a fixed portion and one or more adjustable portions that can be extended or collapsed as needed. The fixed portion comprises multiple sidewalls arranged in serial to form an enclosed structure except for an opening on one or more sides, where a lip takes the place of a wall that would otherwise enclose the fixed portion of the fixed portion. One or more adjustable portions are located adjacent, and attached to the one or more sides of the fixed portion of the base member. While in a partially or fully extended state, the adjustable portions have fully open or partially open bottoms that provide access for the pet to reach fresh grass underneath the cage or to conveniently clean bedding material.

  • Patent number: 10584276
    Abstract: A CO2-sensitive fracturing and displacement fluid contains a surfactant, an auxiliary agent, water, and CO2, wherein CO2 is liquid and/or supercritical CO2. The CO2-sensitive fracturing and displacement fluid provided by the invention does not flow back after completion of fracturing construction, and the gel breaking fluid displacement is carried out after soak for a period of time to improve the tight oil recovery ratio. The CO2-sensitive fracturing and displacement fluid exerts the “one-agent multi-purpose” function of sand carrying, CO2 energization and oil displacement, surfactant imbibition and oil discharge of a fracturing-displacement system in different development and production stages, and achieves the dual goals of expanding the utilization degree of tight oil and improving the displacement efficiency of the tight oil, which can effectively reduce costs and achieve the goal of unified, highly efficient and green development of oil and gas fields.
