The Barrier layer in the ocean is a layer of water separating the well-mixed surface layer from the thermocline.

Reservoir barrier layer systems and methods

A reservoir and a plunger head contained within may be configured to move relative to each other in response to at least one of the reservoir being detached from a base, the base and / or the reservoir being removed from a packaging, and the base and / or the reservoir being moved relative to each other. A first layer may be configured to define a reservoir, the first layer, which may be made of a material compatible with fluidic media in the reservoir, may be adjacent a second layer for inhibiting a diffusion through the second layer. A first layer that may be less than 0.3 mm and made of a cyclic olefin copolymer may be configured to define a reservoir. A reservoir may be defined by a wall made of a cyclic olefin copolymer and the wall may be for substantially preventing light from passing through the reservoir.

Well and layer selection method for pouring measure of large-scale flooding solution into thin and poor layer water-injection well of sandstone reservoir

The present invention relates to a well and layer selection method for a pouring measure of large-scale flooding solution into a thin and poor layer water-injection well of a sandstone reservoir. Themethod mainly solves the problem that stratum energy is not enough to form effective communication between oil-water wells, so as to cause poor water injection capacity of thin and poor layer of an oil well having deficit stratum production capacity and poor filtration capacity. The method is characterized in that: (1) optimizing a target well: selecting a well that has relatively complete well group injection-production relationship, bad oil-water well connectivity, and long-term deficit stratum, wherein the water-injection well is a well having a low porosity, low air permeability and havinga certain exploitation potential; and the water-injection well can satisfy the construction requirement for pouring large-scale fracturing flooding liquid into the water injection well; and (2) optimizing a target layer: selecting a deposition unit with poor producing and great potential as the target layer according to the parameters such as the injection-production relationship of the target well, a reservoir development thickness, a barrier layer thickness, a liquid production capacity, a liquid production intensity, a stratum pressure, producing situation and the like. The method improvesyield-increasing and development effects of the thin and poor layer.

Preparation method of water-oxygen barrier layer

ActiveCN105449123BReduce water oxygen transmission rateEffect of mismatchSolid-state devicesSemiconductor/solid-state device manufacturingWater vaporThin membrane
The invention discloses a method for preparing a water-oxygen barrier layer. At least two film layers are sequentially prepared on a substrate to form a water-oxygen composite barrier layer. When preparing each film layer, at least any two adjacent film layers are prepared Different preparation parameters are provided for selection, so that each film layer in the water-oxygen composite barrier layer forms a mismatch structure in which the water-oxygen micro-channels are not connected. The present invention prepares multi-layer thin film layers on the substrate to form a water-oxygen composite barrier layer, and by adjusting one or several parameters affecting thin film deposition, the thin film can be grown with different structures, different properties or even different growth modes, thereby enabling The water vapor passage in the previous film layer does not match the water vapor passage in the latter film layer, and the water vapor passage that cannot be connected cannot conduct the water and oxygen in the atmosphere, thereby enhancing the water and oxygen barrier performance of the film. The method of the present invention is simple and easy. It has considerable potential for generalization in the industrial production of flexible display barrier layers in the future.
