Embodiment Construction
[0021] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0022] Taking the evaluation of oil-source fault transport capacity in the Zhanhua Sag of the Bohai Bay Basin as an example, figure 2 It is a flowchart of a quantitative characterization method for oil-source fault transport capacity according to an embodiment of the present invention. The method contains the following steps:
[0023] Step 1: Sample point selection
[0024] The Neogene is the main oil-bearing formation in the Zhanhua sag of the Bohai Bay Basin, and the oil and gas come from the lower Shahejie Formation source rocks, which have the characteristics of shallow reservoirs from other sources. Previous studies have shown that oil and gas in the Zhanhua sag migrated to shallow formations mainly through faults. Fault activities in this area have weak damage to oil and gas reservoirs, and shallow oil and gas geological reserves are controlled...

The present invention relates to a quantization representation method of oil source fault transporting capability. The method is based on a fault transporting principle, the geological factors which influence a transporting effect are integrated, a quantization representation model of the oil source fault transporting capability is established, the oil source fault oil and gas transporting capability is subjected to quantization representation, the static characteristic of a fault and the expulsion strength of a hydrocarbon source rock cut by a fault are considered, and the influence of a fault activity time and activity strength on the oil source fault transporting capability is reflected. The applicability of the quantization representation model is determined based on a work area geological background, the analysis is carried out based on an evaluation result, and through fitting shallow layer system proven geological reserve and corresponding oil source fault transporting capability, a favorable exploration area is predicted. Compared with the prior art, according to the quantization representation method provided by the embodiment of the invention, the consideration factors are more comprehensive and rational, the transporting capability of the oil source fault can be more scientifically represented, and thus the exploration is effectively guided.
Description
technical field [0001] The invention belongs to the technical field of oil and gas geological exploration, and in particular relates to a method for characterizing the transport capacity of oil source faults. Background technique [0002] Faults are efficient channels for large-scale and rapid migration of oil and gas, but the levels and types of faults are various, and the ability of different faults to transport oil and gas is not the same. As an important channel for oil and gas migration, faults have always been valued by petroleum workers. Experts and scholars at home and abroad have achieved fruitful results in researches on the internal structure of faults, transport mechanism and evaluation of transport capacity. Caine (1996) believed that the proportion of the fracture zone in the fault is the main factor affecting the transport capacity of the fault zone; Fu Xiaofei et al. (2005) believed that the fracture zone induced by the fault has high porosity and good permea...
