    • In a hollow-fiber permeability apparatus, a permeating region of a housing contains a bundle of hollow fibers, and materials can selectively permeate through the membranes formed by the permeable walls of the hollow fibers, between a first fluid flowing along the exteriors of the hollow fibers, and another fluid flowing the interiors of the hollow fibers. The apparatus includes at least one first opening and at least one second opening for passing the first fluid, formed in both end portions of the housing; an enlarged cross-section portion formed between the first and second openings and surrounding substantially the whole circumferential surface of the bundle of hollow fibers in the housing; and at least one third opening for passing the first fluid, connected to the enlarged cross section portion, said first and second openings being used as a fluid inlet opening, and the third opening being used as a fluid outlet opening, or the first and second openings being used as the fluid outlet opening, and the third opening being used as the fluid inlet opening.

    • A dispersion liquid for supporting oil drilling, including: an aqueous medium and a particulate solid polyglycolic acid resin dispersed in the aqueous medium; wherein the particulate polyglycolic acid resin has a weight-average molecular weight of at least 70,000 and at most 500,000, and exhibits weight retentivities in water at 80° C. of at least 85% after 12 hours, at most 80% after 72 hours, and at most 45% after 168 hours. The particulate solid polyglycolic acid resin included in the above-mentioned dispersion liquid for supporting oil drilling, functions as a fluidity control material exhibiting ideal degradation characteristics in the drilling operation for expansion of oil production capacity, demanded for suppressing the liquid permeability in the early stage and recovery of the liquid permeability after completion of the operation of the formation around the oil well.
    • 一种用于支撑石油钻井的分散液,包括:水性介质和分散在水性介质中的颗粒状固体聚乙醇酸树脂; 其特征在于,所述粒状聚乙醇酸树脂的重均分子量为70,000以上且500,000以下,12小时后,80℃下的水分重量保持率为85%以上,72小时后为80%以上, 168小时后最多45%。 上述用于支撑油钻井的分散液中包含的颗粒状固体聚乙醇酸树脂用作在用于膨胀油生产能力的钻井操作中表现出理想的降解特性的流动性控制材料,需要在早期抑制液体渗透性 并且在油井周围操作完成后恢复液体渗透性。
