Method, device and network device for determining distribution of terrestrial organic matter

Abstract

The application provides a method and device for determining distribution of organic matters, and network equipment, and the method is characterized by comprising the following steps of obtaining thegeological structure characteristic data and organic matter abundance data of a target area; determining a simulated scale and a base type according to the geological structure characteristic data; determining multiple water entry periods of sedimentary simulation according to the sequence stratigraphic analysis results of the target area; determining the ratio of sand and organic matters according to the organic matter abundance data; and performing the sedimentary simulation of the distribution of organic matters in multiple water entry periods according to the simulated scale and the base type, the ratio of sand and organic matters, and the preset water addition and hydrodynamic strength to obtain the distribution state of organic matters in the target working area. In the embodiment ofthe application, in order to determine the distribution of organic matters through forward modeling, the basic information of the target working area is required less, which effectively reduces the cost, and can effectively determine the distribution characteristics of organic matters when the samples in the target working area are scarce.

Description

technical field [0001] This application relates to the technical field of geological exploration, in particular to a method, device and network equipment for determining the distribution of terrestrial organic matter. Background technique [0002] Terrigenous organic matter refers to organic matter derived from lake aquatic organisms and higher plants. Studying the distribution law and controlling factors of terrigenous organic matter can determine the favorable enrichment area of ​​terrigenous organic matter, so as to effectively guide the process of oil and gas exploration and development. [0003] In the prior art, in order to determine the distribution state of terrigenous organic matter in the delta-shallow sea sedimentary system, it is generally characterized by geochemical parameters and biomarker compounds such as the overall carbon stable isotope, nitrogen stable isotope ratio, BIT, and lignin content of the organic matter, and according to the data Draw isoline map...
