摘要： A device for evaluating the foaming property of a gas-soluble surfactant, which comprises a gas source part, an evaluating kettle, a liquid part, and an intermediate container part. By means of the rotation of the evaluating kettle, the gas-soluble surfactant and the supercritical carbon dioxide can be sufficiently and evenly mixed with each other when the solubility of the gas-soluble surfactant in the supercritical carbon dioxide is measured.

摘要： A novel inorganic fine particle reinforced foam system for an oil-gas field and preparation method thereof. The reinforced foam system comprises a gas phase and a liquid phase; the gas phase is nitrogen, carbon dioxide or the air; the liquid phase is prepared from, by mass: 0.2-0.8 wt % of a foaming agent, 0.5-2.0 wt % of novel inorganic fine particles and balance of water; the novel inorganic fine particles are fine particulate matter with diameters being smaller than or equal to 2.5 microns captured and screened from the atmosphere.

摘要： Disclosed is a method for performing integral plugging control on water invasion and steam channeling of an edge-bottom water heavy oil reservoir. The method for performing integral plugging control on water invasion and steam channeling of an edge-bottom water heavy oil reservoir comprises the following steps: (1) selecting an oil reservoir; (2) arranging a huff-puff well; (3) performing steam huff-puff development; and (4) performing integral plugging control. An integral plugging control technology is used for the method, a high-strength nitrogen foam system is injected by means of well rows at different positions in the oil reservoir, and effective plugging walls are formed at different positions from the edge-bottom water to reduce water invasion and steam channeling.
