Example Embodiment

[0063] Example 1:

[0064] A device for simulating natural gas micro-leakage with a column length of 2 m is used to simulate the conditions of natural gas micro-leakage, and the quantity changes and population development of indicator microorganisms in surface soil oil and gas are regularly monitored; at the same time, the same structure is used to simulate natural gas micro-leakage. The device is not equipped with an air source and is not ventilated as a control soil column for comparison.

[0065] 1. Before the start of the experiment, check the pipeline connection and whether the valve is closed.

[0066] 2. Open the exhaust port 27, and supply the simulated gas into the device through the gas inlet 22 from the simulated gas source 24.

[0067] 3. Regularly take soil samples through the sampling ports 1-3, the amount of soil samples taken each time is 20g, at the same time, the air tightness of the detection device and the physical and chemical properties of the soil samples, where...

Abstract

The invention relates to an apparatus for simulating natural gas micro-leakage. The apparatus comprises a cylinder and two detachable sealing covers arranged at both ends of the cylinder and used forsealing the cylinder, wherein the cylinder is sequentially provided with a gas storage chamber, a filling chamber and a gas inlet buffer chamber from upstream end to downstream end, the filling chamber is filled with soil, at least a sampling port is arranged on the side wall of the filling chamber, an air pressure gauge is arranged on the side wall of the gas storage chamber, the gas inlet bufferchamber is separated from the filling chamber through a separation layer I, the side wall of the gas inlet buffer chamber is provided with a gas inlet, and the gas inlet is connected to a simulatinggas source. According to the present invention, the apparatus is used for simulating natural gas micro-leakage; during the detecting, the air pressure tightness is good, and the soil pH value and thesoil moisture are basically maintained, such that the natural gas micro-leakage can be well simulated so as to achieve the desired effect; and the apparatus can be used for simulating the natural gasmicro-leakage conditions under the artificial simulation conditions, can regularly monitor the quantity change and the population development condition of earth surface soil hydrocarbon microorganisms, and can provide the basic theoretical support for actual field exploration.

Description

technical field [0001] The invention belongs to the technical field of the application field of oil and gas microbial exploration, and relates to a device for simulating micro-leakage of natural gas and its application. Background technique [0002] Oil and gas microbial exploration is a rapidly developed and recognized effective oil and gas exploration method in recent years. This technology predicts the distribution of underground oil and gas reservoirs by studying the number and community anomalies of oil and gas indicator microorganisms in surface soil. Microbial exploration of oil and gas needs to be based on the research of forward modeling. The forward modeling process is to collect and determine the surface soil samples of oil and gas areas and non-oil and gas areas, and analyze the differences in the number and community of oil and gas indicator microorganisms between the two in the microbiological laboratory. However, in the process of forward modeling, exploration...
