Method and device for calculating gas drainage radius of low-permeability tight gas reservoir, electronic equipment and storage medium

Abstract

The application discloses a kind of low-permeability tight gas reservoir blowout radius calculation method, device, electronic equipment and storage medium.Its features include: the gas area controlled by target gas well is divided into multiple unit gas reservoir regions;According to the average original water saturation, average reservoir effective thickness, average porosity and average natural gas volume coefficient of each unit gas reservoir region in the target gas well, the geological reserves of the unit gas reservoir region are determined;According to the dynamic reserves of the target gas well and the geological reserves of each unit gas reservoir region, the target gas reservoir region of the target gas well is determined;According to the number of target gas reservoir region and the preset area of unit gas reservoir region, the blowout radius of the target gas well is determined.The precision calculation of low-permeability tight gas reservoir blowout radius is realized, the blowout radius precision is effectively improved, more accurate data is provided for oil and gas production, production efficiency is improved, and production cost is reduced.
