Embodiment Construction

[0017] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail through specific embodiments. Obviously, the described embodiments are only some, but not all, embodiments of the present invention.

[0018] (1) Simulation of hydrostatic environment: inject nutrient salt solution into the cylinder Add a certain amount of algae liquid, set the temperature of the temperature control device ⑩, turn on the LED light source, and turn on the air pump ④, the gas drives the solution to gradually rise from the guide pipe ①, and is discharged from the top of the cylinder, turning into a weak water flow, so as to prevent It will affect the sediment on the deposition baffle ⑧;

[0019] (2) Artificially prepared simulated water samples (such as artificial rainwater, clay solution) can be injected into the reactor through ⑤ by constant flow pump ③ at a certain flow rate. Simulate the actual environment and realize the ...

Abstract

The invention discloses an experimental device for simulating the biogenesis and deposition process of fine-grained carbonate. part. Among them, multiple reactor columns can be connected in series to realize the simulation of different water depths; the aeration system includes air pumps, rotameters and diversion tubes, and the diversion tubes are used for diversion of air bubbles; sedimentation baffles are used for sediments at different water depths The collection and sampling observation; the injection system is used to simulate the input of rainwater and minerals; the temperature control system and lighting system are used to simulate the natural temperature and light intensity. Its advantage is that it integrates the blooming of simulated algae, the biochemical formation process of carbonate and the deposition process of minerals. It is an effective combination of biochemical action and deposition process, and provides an experimental basis for exploring the biogenesis of carbonate.

Description

technical field [0001] The invention belongs to the field of biogeology, and in particular relates to an experimental device for simulating the biogenesis and deposition process of fine-grained carbonate. Background technique [0002] my country is rich in shale oil reserves. With the intensification of shale oil exploration and development, the study of fine-grained sedimentary rocks has received more and more attention. Fine-grained carbonate minerals are an important part of shale. Exploring the origin of fine-grained carbonates can provide an important theoretical basis for fine-grained carbonate deposition, laminar identification, and paleoenvironment reconstruction, so as to better serve the Oil and gas exploration and development. According to literature reports, fine-grained carbonates are presumed to be produced by biochemical action. The carbonate of biological origin is in a suspended state at first, and gradually settles from the surface of the water body to th...
