Abstract

The invention discloses a method and device for determining the well pattern density of an oil reservoir, and relates to the technical field of oil field development. An upper computer can determine the target well pattern density based on an income amount function and an expenditure function, the income amount function can reflect the relationship between a discount value of the crude oil sales income and the well pattern density, and the income amount function can reflect the relationship between the discount value of the crude oil exploitation expenditure and the well pattern density. According to the method for determining the well pattern density of the oil reservoir, in the process of determining the well pattern density, the time value of funds is considered, so that compared with the well pattern density determined in the related technology, the accuracy of the well pattern density determined through the method is high.

Description

technical field [0001] The present application relates to the technical field of oil reservoir exploitation, in particular to a method and device for determining the well pattern density of an oil reservoir. Background technique [0002] Well pattern density refers to the number of wellheads per unit area of ​​an oilfield, which is directly related to the recovery rate of the oil reservoir, and then to the economic benefits of oilfield development. Therefore, before the development of the reservoir, it is necessary to determine the well pattern density. [0003] In related technologies, the calculation formula of the intersection method derived from the Serkachov formula is generally used to determine the well pattern density. However, in the related art, the accuracy of the determined well pattern density is low. Contents of the invention [0004] The present application provides a method and device for determining the well pattern density of an oil reservoir, which can...
