Abstract

The invention provides a simulating method of the burial evolution process of argillaceous sediments. Silt is used as a starting point of an experiment, based on making a reasonable temperature rising pressure increasing scheme, a modern advanced in-situ monitoring technique is used, an automated technique is matched, and the change rule of indexes of water, ore, gas, organic matters and microorganisms in the process of the experiment are dynamically monitored, so that the lengthy geological process of the burial evolution of the argillaceous sediments can be retraced within limited time in a laboratory, what's more, the water-ore-gas-microorganism interaction mechanism in the evolution process can be revealed by simulating the change rules of the indexes in the process, the corresponding action model is established, and the contribution of sludge water release consolidation to the water volume and the water quality of a water-bearing layer in a clay water resisting layer (or clay lenticle) process can be quantitatively evaluated.

Description

technical field [0001] The invention relates to a method for simulating the burial evolution process of argillaceous sediments, and relates to the fields of hydrogeology and sedimentology Background technique [0002] Silt is a kind of fine-grained water-saturated unconsolidated and fluid sediment in modern storage basins. It is mostly deposited in the discharge area of ​​the groundwater system, including oceans, lakes, deltas, wetlands, rivers, etc., and belongs to the stagnation zone of water. It is an important "sink" in the material cycle. It plays an important role in many fields of earth science, and its importance is reflected in the following aspects: (1) in the field of sedimentology, silt is the starting point of mud shale deposition; (2) in the field of energy, the organic matter in silt is the The origin of many mineral resources has formed solid coal, liquid petroleum and gaseous natural gas during the long geological evolution process; (3) In the field of engi...
