摘要： A nitrogen-carbon dioxide mixed gas jet apparatus for a horizontal well and an exploitation method is presented. The jet apparatus includes: an offshore platform, a natural gas processing unit, and a pressurizing unit, wherein a portion of the gas exploitation pipe in the hydrate layer is provided with a gas injection horizontal well; a mixed gas jet unit and a nozzle assembly are disposed in the gas injection horizontal well; the mixed gas jet unit is configured to mix nitrogen and carbon dioxide, and then inject the mixed gas into a hydrate deposition layer through the nozzle assembly, so that the mixed gas replaces methane gas in the hydrate deposition layer; the portion of the gas exploitation pipe in the hydrate layer is provided with a gas exploitation horizontal well configured to collect the methane gas and convey the methane gas to the natural gas processing unit.

摘要： In gas hydrate inhibitor formulations used to prevent or inhibit the formation of gas hydrates in multi-phase fluids, such as hydrocarbon production fluids, conventional solvents can be largely replaced by at least one organic carbonate solvent, such as ethylene carbonate, propylene carbonate, and/or glycerol carbonate. The gas hydrate inhibitors in these formulations may be, but are not necessarily limited to, polyesteramides, polyvinylpyrrolidones, and the like. The use of an organic carbonate in the gas hydrate inhibitor formulation can improve the capability of the formulation for inhibiting or preventing gas hydrate formation in a multi-phase fluid.

摘要： Disclosed herein is a wellbore servicing fluid comprising a scale inhibitor, a surfactant, and an aqueous fluid comprising sulfate in an amount of from about 100 ppm to about 10,000 ppm based on the total weight of the aqueous fluid. The wellbore servicing fluid can be used as a fracturing fluid in a method of servicing a wellbore penetrating a subterranean formation. The wellbore servicing fluid can mitigate the formation of scales, prevent water blockage, and increase hydrocarbon production.

摘要： The subject invention provides microbe-based products, as well as their use in simultaneously enhancing oil recovery from an oil well while efficiently removing contaminating compositions such as biofilm, scale, paraffin, and/or asphaltenes from oil production equipment and oil-bearing formations. The subject invention can also be used to disperse paraffin and asphaltene precipitates, and to reduce the viscosity of heavy crude oil. The subject invention further provides materials and methods for bioremediation of hydrocarbon-contaminated sites.
