The mixed stream is passed through at least one of the separation flow channels, where methane is sorbed. The contactor can be regenerated by contacting the contactor with a heat exchange fluid via the barrier layer at one or more of the external surfaces.

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.
