Abstract

The invention provides an oil-gas exploration optimization method and device. The method comprises the following steps: determining a data interval mean value of drilling historical data and earthquake historical data in a set time range; wherein the data interval mean value comprises a drilling seismic exploration engineering cost data interval mean value and a drilling seismic exploration engineering effect data interval mean value; calculating recoverable reserves according to an oil-gas exploration reserve expected target; determining the discovery cost according to the international crude oil price; wherein the discovery cost comprises petroleum discovery cost, natural gas discovery cost and oil gas discovery cost; calculating drilling capabilities of different oil and gas fields according to the drilling historical data; and inputting the data interval mean value, the recoverable reserves, the discovery cost and the drilling capability into a pre-established plan optimization model, and performing oil-gas exploration optimization. The data interval mean value, the recoverable reserves, the discovery cost and the drilling capacity can be input into the pre-established plan optimization model, and oil-gas exploration workload and investment optimization is carried out.

Description

technical field [0001] This application relates to the field of oil and gas exploration, in particular to an oil and gas exploration optimization method and device. Background technique [0002] Oil and gas exploration planning refers to the overall deployment of exploration work in a certain exploration area (such as an address depression, a sedimentary basin, a province or a country, etc.) within a certain period of time (such as one year or a five-year plan, etc.) and stage arrangement. Whether an exploration plan is correct or not is related to whether the exploration can achieve the expected purpose, or whether it is related to huge economic benefits. Therefore, relevant personnel who formulate exploration plans must have a scientific attitude and master relevant quantitative methods. In 1999, Zhang Xia analyzed the importance and characteristics of oil and gas field exploration plans, put forward the principles and ideas for the preparation of oil and gas field explo...
