Abstract

The embodiment of the invention discloses a method and device for establishing a net present value prediction model,, a storage medium and electronic equipment, and the method comprises the steps: carrying out the training of a back propagation neural network model based on a dispersed fault block oilfield development database, generating an initial net present value prediction model, and determining the network parameters and MAPE of the initial net present value prediction model; repeating the operation of training the back propagation neural network model based on the dispersed fault block oilfield development database for N times to obtain corresponding network parameters and MAPE corresponding to N initial net present value prediction models; and optimizing the N groups of network parameters and the MAPE based on an empire competition algorithm until a group of optimal network parameters remain, and returning the optimal network parameters to the back propagation neural network model to generate a target net present value prediction model. Through the scheme, the prediction precision and efficiency of the net present value of the dispersed fault block oil field group are improved, and objective and accurate evaluation of the dispersed fault block oil field group is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of oilfield development, and in particular to a method, device, storage medium and electronic equipment for establishing a net present value prediction model. Background technique [0002] The contradiction between supply and demand of domestic oil resources is increasing day by day. With the internationalization of my country's oil and gas exploration and development, a large number of overseas fault-block oil fields are in urgent need of development. Overseas fault-block oilfields are highly complex, numerous and scattered, usually forming a certain scale of scattered fault-block oilfields. The complex fault-block oilfields in the overseas scattered fault-block oilfields have various structural types, large differences in reservoir and fluid characteristics, and different types of natural energy. Great difficulty. [0003] In related technologies, the determination of the commis...

AI Technical Summary

Problems solved by technology

The complex fault-block oilfields in the overseas scattered fault-block oilfields have various structural types, large differences in reservoir and fluid characteristics, and different types of natural energy. high difficulty

[0003] In related technologies, the determination of the commissioning or development sequence of fault-block oilfields is mainly determined artificially based on fault-block reservoir morphology, reservoir geological characteristics, distribution of remaining oil, reservoir development methods, and natural energy, which cannot be quantified

As for the quantitative determination of the commissioning or development sequence of fault-block oilfields, existing methods include weight evaluation method, analytic hierarchy process, comprehensive fuzzy evaluation method, etc. Such methods are highly subjective in selecting evaluation indicators and index weights. Can't do accurate evaluation

The complex fault-block oilfields in overseas scattered fault-block oilfields have various structural types, large differences in reservoir and fluid characteristics, and different types of natural energy. The above-mentioned method for a single fault-block oilfield cannot be used for the development of overseas scattered fault-block oilfields Accurate determination or evaluation of the sequence is difficult to provide effective theoretical support for the development strategy of overseas scattered fault-block oilfields
