Abstract
The invention discloses a heat-sensitive umbrella type folded multilayer packer, which comprises a power module, a packing module and a mining module; a double-power head of the power module drives a movable outer pipe in the mining module to move up and down, and further drives the heat-sensitive umbrella type packing module capable of being axially folded and radially expanded to move up and down; a fixed central pipe with a double-layer structure in the mining module is fixedly connected with the double-power head; the fixed central pipe with the double-layer structure can be used as a passage for mining and transporting target minerals, and the packing effect of double-layer high-temperature resistant rubber is effectively improved by designing a bionic upper bow arm; and the umbrella type folded rod system structure and multiple groups of structures of the packing module can be selected according to the packing requirement, so that multilayer packing is realized. By using the packer, the mining purity of minerals such as oil shale and the like can be effectively improved, and cross contamination among the reservoirs in the mining process is reduced.
Description
Technical field
The present invention relates to a kind of multiple packer, be specifically related to a kind of umbrella formula folded form multiple packer that adopts the thermometal sheet, during for mineral such as producing oil shale, the mineral between upper and lower reservoir are carried out to packing effectively.
Background technology
Gas hydrates are a kind of solid chemical compounds that generated under the cryogenic high pressure condition by methane and water at land permafrost band, have the characteristics wide, that reserves are huge that distribute; In addition, sometimes need to extract the underground water of certain one deck position during groundwater abstraction, prevent from polluting mutually between the underground water of different layers position; During the mineral such as producing oil shale, only needs are exploited the mineral of certain one deck position and are not whole mineral usually.
Therefore, want to realize the purpose of only exploiting, transporting a certain certain layer position target mineral, must use packer to be realized.
Existing packer mostly is single-layer packing, and the packing effect is not very desirable, causes the mineral such as gas hydrates between upper and lower reservoir, underground water, oil shale to pollute mutually, and the quality of quarry thing is had a negative impact.
Summary of the invention
The present invention is for addressing the above problem, and a kind of easy and simple to handle, simple in structure, heat-sensitive umbrella type folded multilayer packer of underlying strata being had to good packing effect is provided.
