Embodiment Construction

[0044] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0045] The essence of the existing problems in the prior art is information mining and intuitive interactive display of multi-dimensional attributes of exploration objects. In view of the above-mentioned problems in the field of petroleum exploration and development, it is positioned to further enhance the various multivariate statistical analysis capabilities of massive data, and introduce parallel coordinate visualization technology to reflect the changing trend of multi-dimensional information and the relationship between variables.

[0046] This method is based on the evaluation of geological factors of a single exploration target, and based on the software of parallel coordinates, the geological risk assessment of multiple exploration targets is carried out. The geological risk assessment results provide auxiliary decision-making for the selection of exploration t...

Abstract

The invention provides a multi-factor geologic risk evaluation method based on parallel coordinate and belongs to the field of geologic risk evaluation of oil-gas exploration. According to the method, on the basis of geological factor evaluation of a single exploration target and through a parallel coordinate method, geological factor evaluation of a plurality of exploration targets can be carried out. The method comprises the following steps: 1) parallel coordinate display of reservoir forming elements of the exploration target: on the basis of evaluation result of the reservoir forming elements of the single exploration target, directly displaying geological factor evaluation results of the plurality of exploration targets through the parallel coordinate method; 2) clustering analysis based on parallel coordinate display; and 3) primary factor and correlation analysis: on the basis of category division of the exploration targets, further analyzing primary factors of the same kind of exploration targets through parallel coordinate visual display, and analyzing correlation with each primary control factor through a coordinate axis interaction mode.

Description

technical field [0001] The invention belongs to the field of geological risk assessment of oil and gas exploration, and in particular relates to a multi-factor geological risk assessment method based on parallel coordinates. Background technique [0002] Oil and gas exploration is a high-risk, high-tech, high-investment and high-return business activity. Multinational oil companies have been using various technologies to identify, analyze, and manage various possible risks in the exploration process in order to reduce risks and Get maximum economic benefit. Among them, the most core and essential among many risks is geological risk. [0003] At present, the geological risk analysis for exploration objects (such as basins, oil and gas accumulation systems, plays, traps, oil and gas reservoirs, wells, etc.) mainly adopts special geological research or comprehensive geological evaluation to obtain the values ​​of various geological parameters of the exploration objects. Refer...
