Risk exploration well exploration decision-making method and system

Abstract

A risk exploration well exploration decision-making method and system, the method comprising: step 1: calculating the exploration well success probability and value of the risk exploration well, and calculating the post-risk value of the risk exploration well according to the exploration well success probability and value; step 2: calculating the risk exploration well cost According to the accumulation condition index and engineering risk index, the geological engineering index of the risk exploration well is calculated according to the accumulation condition index and engineering risk index; Step 3: Normalize the post-risk value and the geological engineering index; Step 4: Set the post-risk value The weight coefficient and the geoengineering index weight coefficient are calculated, and the risk exploration well index of the risk exploration well is calculated according to the post-risk value weight coefficient and the geoengineering index weight coefficient, as well as the normalized post-risk value and the normalized geoengineering index. The method comprehensively evaluates risk exploration wells based on the economic value, geological conditions and engineering technical risks of risk exploration wells. It has good operability and practicability, and has a wide range of applications.

Description

technical field [0001] The present invention relates to the technical field of oil and gas exploration, in particular to a risk exploration well exploration decision-making method and system. Background technique [0002] Risk exploration wells refer to exploration wells that have strategic exploration significance and scientific exploration significance for oil companies within a certain period of time, and are expected to make major breakthroughs. Risk exploration wells are different from ordinary pre-exploration wells. The main difference is that risk exploration "highlights strategic guidance, highlights major discoveries, highlights resource scale, and highlights three new fields". Emphasis is placed on strategic targets for the Great Basin and new territories. [0003] The decision-making process for the optimal deployment of domestic risk exploration wells mainly includes three stages: ①The oilfield branch company provides risk exploration wells and reports to the he...
