Problems solved by technology

Due to the inconsistency of geological risk parameters, more qualitative analysis and less quantitative analysis, there is no mature and unified evaluation technical specification standard for the evaluation of predicted reserve blocks in the existing technology
Therefore, the methods in the prior art cannot quantitatively realize the unified screening of predicted reserve blocks in different regions and fields

Abstract

The invention discloses a screening method for predicted reserve blocks. The method comprises steps: the upgrading reliability of to-be-screened predicted reserve blocks and the reserve values are subjected to quantitative calculation; according to limitations of screening results, screening thresholds for the upgrading reliability and the reserve values are calculated and acquired; and the quantitative calculation results of the upgrading reliability and the reserve values are integrated, and according to the screening thresholds, the to-be-screened predicted reserve blocks are screened. According to the method, predicted reserve blocks in different areas and different fields can be simply and quickly screened on a unified platform; and compared with the prior art, the method greatly reduces interference of human factors during the screening process, the screening result reliability is greatly improved, and a powerful basis is provided for exploration focus and order determination, investment optimization and plan making for an oil company.

Description

technical field [0001] The invention relates to the field of geological development, in particular to a screening method for predicted reserve blocks. Background technique [0002] According to the current reserve management system in my country, oil and gas reserves are divided into three levels: proven reserves, controlled reserves, and predicted reserves. Among them, predicted reserves are the lowest level, and will be gradually upgraded to probable reserves and proven reserves according to the improvement of exploration degree. [0003] Analysis and evaluation of predicted reserve blocks is the basis for oil companies to formulate exploration plans and medium and long-term plans. In the current existing technology, although there are classification standards and calculation specifications for the predicted reserves, the evaluation of the predicted reserves block is mainly to evaluate the geological risk. Due to the inconsistent geological risk parameters, more qualitat...
