Oil soluble cationic broad-spectrum temporary blocking agent in use for drilling fluid

This invention relates to an oil-soluble cationic broad-spectrum temporary blocking agent for well drilling fluid. The oil-soluble cationic broad-spectrum temporary blocking agent comprises: oil-soluble materials 50-74%, SBS triblock copolymer 0.2-0.44%, epoxypropylbenzyl di(stearamide ethyl) ammonium salt 0.50-0.89%, cationic surfactant imidazoline 0.62-0.96%, dibenzyl-di(stearamide ethyl) ammonium salt 0.62-0.96%, carboxymethyl cellulose or hydroxyethyl cellulose 0.17-0.84$, CaCl2 0.2-0.25%, and water as balance. The oil-soluble materials include residue asphalt (softening point = 51-55 deg.C), semi-oxidized asphalt (softening point = 57-65 deg.C), ethylene pyrolysis coal tar pitch (softening point = 47-52 deg.C), propane-removed asphalt (softening point = 70-77 deg.C), extracted asphalt (softening point = 105-120 deg.C), and 100# heavy oil asphalt (softening point = 47-54 deg.C) at a weight ratio of 1:(1.88-2.5):(1.25-1.88):(3.12-3.75):(2.5-3.12):(1.5-2). The oil-soluble cationic broad-spectrum temporary blocking agent has such advantages as high oil solubility, high softening degree, wide softening point range, strong positive electricity, high lubricity, good fluid-loss inhibitive effect, high recovery rate of core permeability, low temporary blocking depth, high strength, good de-blocking effect, no pollution, low labor intensity, little influence on well drilling fluid construction performance, and simple process.

Three-layer medical infusion bag and manufacturing method thereof

The invention aims to provide a three-layer medical infusion bag. The three-layer medical infusion bag comprises a flat infusion bag body of a three-layer structure. The three-layer structure comprises an inner bag layer made of polyethylene material, a middle bag layer made of polypropylene and styrene-ethylene/ butylene-styrene segmented copolymer material and an outer bag layer which is a blended layer of polypropylene, carboxylated styrene-ethylene/ butylene-styrene segmented copolymer and anionic polymerization nylon nanocomposite. The barrier performance of the anionic polymerization nylon nanocomposite of the outer bag layer is excellent. Air inlet is not needed in the infusion process and medicine liquid can automatically flow and is completely drained through the design of the thickness and the width of the infusion bag body, and therefore the whole infusion bag is good in safety, barrier property and infusion performance. The invention further provides a manufacturing method of the three-layer medical infusion bag. One-time injection molding and air blowing are conducted through a three-die-head injection molding die, the whole process is simple and advanced, one-time forming is achieved, the method is suitable for production of the infusion bag, and the manufactured infusion bag meets the infusion requirement.
