Research On Intelligent Decision Of Oil And Gas Field Development Schemes Based On Big Data

For a new oil reservoir,the oilfield development plan is of great significance to increase crude oil recovery and obtain higher economic benefits.At present,the development schemes formulation methods mainly include reservoir engineering and numerical simulation.The two methods are widely used.However they often take a long time to establish various models and there are errors between the models and the actual performances of the reservoir,which may make the development plans unreasonable.In order to overcome the above shortcomings,this paper carries out research on intelligent decision of oil and gas field development schemes based on big data.In this paper,the index system of oil and gas field development effect is established,and the fuzzy and multivariate evaluation method is used to evaluate the development effect of a large number of reservoirs that have been developed steadily for a long time.The reservoir development plans with excellent effect are selected to establish a sample database of development schemes.Secondly,the main control factors of development modes,injection and production patterns,water injection timing and pressure maintenance level,well spacing density and production well’s working system are determined.Finally,the intelligent decision of oil and gas field development schemes based on big data is used to select the block most similar to the main control factors of the block to be formulated in the sample database,so as to determine the development plan of the block to be formulated.This paper selects a block in the sample database of development plans and uses it as a block to be formulated to verify the intelligent decision of the oil and gas field development plan based on big data.The result shows that the development plan obtained by it is very close to the actual development plan of the block.And the intelligent decision is accurate.This method provides a faster and more reliable decision approach for oil and gas field development programs.
