Oil and gas field asset evaluation method and device

Abstract

The invention provides an oil and gas field asset evaluation method and device, and relates to the technical field of oil and gas exploration and development, and the method comprises the steps: obtaining oil and gas field basic parameters and bid invitation contract evaluation parameters; according to the recovery ratio data, the recovery degree data, the storage and production ratio data and the geological reserve data, determining a peak period yield and peak period stable yield period prediction model; determining a yield and workload prediction model according to the storage and production ratio data, the oil production speed data, the decline stage yield data, the yield increase yield data and the single well productivity data; determining a well group optimization prediction model according to the recovery ratio data, the reservoir effective thickness data, the well spacing data and the permeability data; and generating an oil and gas field asset evaluation result according to the peak period yield and peak period stable production period prediction model, the yield and workload prediction model and the well group optimization prediction model. According to the method, the prediction speed is optimized, and a more accurate prediction result is obtained based on limited parameters.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to an oil and gas field asset evaluation method and device. Background technique [0002] The focus of technical evaluation of oil and gas field assets is to determine the production and workload profiles in the medium and long term. The existing medium and long-term planning methods mainly include the following: numerical simulation method, generalized forecasting model method, 5-year production composition method, and dynamic control prediction method of reserve-production ratio, etc. For some cases, for example, in the acquisition of new overseas projects, it is necessary to complete the medium and long-term evaluation plan according to the contract period. Usually, it is necessary to face the problems of less available data and short evaluation time. It is extremely difficult, even impossible, to obtain more accurate evaluation results. Content...
