Embodiment 1

[0045] When the buried depth of the ore seam is 900m, the heat injection temperature is 400°C, and the pyrolysis sample is block, the specific operation steps of the reaction device of the present invention are as follows:

[0046] 1. Place the lower perforated plate 15 with a hole diameter lower than the sample block size on the clasp 14 of the high-temperature and high-pressure L-shaped reactor 13, and then fill the pre-soaked block sample in the supercritical water-oxygen reaction zone, and fix the high-temperature and high-pressure first method Lan 8, a perforated plate 9 is placed on the end of the axial pressure transmission rod 3, thereby applying a pressure of 23.4 MPa to the block sample;

[0047] 2. Connect the high temperature and high pressure L-shaped reactor 13 with the drainage (salt) system and the oil and gas condensation and collection system, and set the pressure of the first back pressure valve 29, the second back pressure valve 30 and the third back pressur...

Embodiment 2

[0054] When the buried depth of the ore seam is 1200m, the heat injection temperature is 380°C, and the pyrolysis sample is powder, its specific operation steps of the reaction device of the present invention are as follows:

[0055] 1. Place the lower porous plate 15 with a hole diameter lower than the particle size of the powder sample on the clasp 14 of the high-temperature and high-pressure L-shaped reactor 13, and then fill the supercritical water-oxygen reaction zone with pre-soaked powder samples to fix the high-temperature and high-pressure first method Lan 8, a perforated plate 9 is placed on the end of the axial pressure transmission rod 3, thereby applying a pressure of 30 MPa to the powdery sample;

[0056] 2. Connect the high temperature and high pressure L-shaped reactor 13 with the drainage (salt) system and the oil and gas condensation and collection system, and set the pressure of the first back pressure valve 29, the second back pressure valve 30 and the third...

Abstract

The invention relates to an L-shaped powder or blocky organic rock supercritical water-oxygen reaction device and a using method thereof, and belongs to the technical field of special mining of unconventional or conventional resources difficult to mine in the deep part. According to the technical scheme, the device comprises an L-shaped reaction kettle, an axial pressure transfer rod, a water injection system, an oxygen injection system, a water (salt) drainage system and an oil-gas condensation and collection system, wherein a kettle body of the L-shaped reaction kettle is divided into a supercritical water-oxygen reaction area, a high-temperature oil-water area and a low-temperature gas area; the reaction device can simulate the process and characteristics of supercritical water and oxygen synergistic in-situ pyrolysis of blocky or powdery organic rocks with different granularities and can simultaneously exploit oil and gas in real time, is suitable for the geological environment with large burial depth, can perform segmented heating, and can realize the regional supercritical water-oxygen pyrolysis reaction of the organic rocks; oil-gas-water can be efficiently separated in real time; and oxygen is injected into a pyrolyzed sample through the oxygen injection system, and the oxygen flows slowly in the horizontal section, so that sufficient reaction with the organic rocks is ensured, and the explosion risk is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of special mining of unconventional or conventional resources that are difficult to mine deep, and specifically relates to an L-shaped organic rock supercritical water-oxygen reaction device and a use method thereof. Background technique [0002] China has abundant reserves of organic-rich rocks (coal, oil shale, etc.). my country's national conditions are poor in oil and gas, and the pyrolysis of organic rocks can form oil and gas products, which is of great significance for alleviating the current shortage of oil in my country. The resource reserves of different burial depths are also different. For the ore layer with a shallow burial depth of 500m, underground mining or in-situ mining can be used. In situ mining, high-temperature fluid (>550°C) is directly injected into the heat injection well. After the organic matter is fully pyrolyzed, the fluid The product can then be drained from the production w...
