Shale oil-gas separation exploiting system

Abstract

The invention discloses a shale oil-gas separation exploiting system which comprises an emitting portion, a collecting portion and multiple plumb shaft arrays which are arranged in a regular hexagon and are of a honeycomb structure. The emitting portion is provided with emitting shafts and sound wave emitters arranged in the emitting shafts. The collecting portion is provided with exploiting shafts and gas collecting devices arranged in the exploiting shafts. The emitting shafts are arranged in the geometric center of the regular hexagon and the exploiting shafts are arranged at the six angle vertices of the regular hexagon or the exploiting shafts are arranged in the geometric center of the regular hexagon and the emitting shafts are arranged at the six angle vertices of the regular hexagon. Sound waves emitted by the sound wave emitters around each exploiting shaft are collected, resonance and superposition of gaps and cracks of the sound waves are generated, so that light shale gas overflows from the inner walls of the exploiting shafts through vibration, the diffusion property of particle substances is used, and the shale gas of a mineral deposit seeps into the gas collecting device continuously. According to the shale oil-gas separation exploiting system, chemical agents are not needed, so that the system has no harm to the environment, the technology can be simplified, consumption of water can be reduced, and the exploiting efficiency is high.

Description

technical field [0001] The invention relates to the field of shale oil and gas exploration and production, in particular to a shale oil and gas separation and production system. Background technique [0002] Shale oil and gas are the components of shale oil and gas extracted from shale formations. The main body is located in dark mud shale or high-carbon mud shale, and the main body exists in mudstone, high-carbon mudstone, and shale in an adsorbed or free state. And in silty rock interlayers, it can be generated in various stages of organic origin. On the main body of natural gas, it exists in fractures, pores and other storage spaces in a free phase state (about 50%), and in an adsorption state (about 50%) It exists on the surface of kerogen, clay particles and pores, and a very small amount is stored in kerogen, asphaltene and petroleum in a dissolved state. At the same time, it also exists in interlayered siltstone, silty mudstone, argillaceous siltstone, and even sands...

Problems solved by technology

Based on the above conditions and the characteristics of water shortage in some mining sites, the common method of using a large amount of hot steam to inject deep underground layers to heat and crack shale oil and gas is not suitable for water-scarce areas. The exploitation of shale oil and gas under the environment has become one of the important technical issues that need to be considered in the exploitation of oil shale oil and gas in water-scarce areas.
