Adjustment and storage capacity calculation method for underground reservoir

Abstract

The embodiment of the invention discloses a adjustment and storage capacity calculation method for an underground reservoir. The method comprises the following steps: step 100, defining a storage capacity range of the underground reservoir; step 200, determining a characteristic water level; step 300, obtaining a stratum single-well histogram in the reservoir capacity range, re-defining the reservoir capacity range and establishing a geological structure body, and importing a characteristic water level into the geological structure body; 400, constructing an underground water level contour mapbased on the current water level measured by the geologic structure body through a plurality of long-viewing water level wells in the reservoir capacity range; 500, calculating the corresponding relation between the current water level and the reservoir capacity of the long-observation water level well based on the corrected geologic structure body, and calculating the adjustment and storage capacity; according to the method, the structure of the geologic structure reappearing underground reservoir is constructed, water level distribution is obtained on the basis of the current water level measurement result of the long-viewing water level well, and then the accurate value of the adjustment and storage capacity and difference distribution in the storage capacity range are obtained throughthe relation between the water level distribution and the storage capacity.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of storage capacity calculation methods, and in particular to a storage capacity calculation method for underground reservoirs. Background technique [0002] The regulation and storage storage capacity refers to the water storage volume of the underground reservoir corresponding to the normal water storage level to the stagnant water level, and it is an important indicator of the regulation and storage capacity of the underground reservoir. Among them, under the premise that the current technical and economic conditions permit and will not cause negative environmental effects, the maximum draining water level allowed by the underground reservoir is called the dead water level, which is the critical water level for whether the underground reservoir loses its ability to regulate. The volume is called dead storage volume. Under the premise of long-term water storage without causing ne...
