Embodiment Construction

[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0055] Interpretation of professional terms:

[0056] Reservoir: Refers to the basic accumulation of oil in a single trap with the same pressure system. If only oil is accumulated in a trap, it is called an oil reservoir; if only natural gas is accumulated, it is called a gas reservoir.

[0057]Oil-source faults: faults that connect source ...

Abstract

The invention provides a well site deployment region determining method and device and a storage medium. The method comprises the steps that firstly, the oil source fracture condition of a to-be-developed oil reservoir is obtained; and then a well site deployment region of the to-be-developed oil reservoir is determined according to the oil source fracture condition of the to-be-developed oil reservoir and a preset well site deployment strategy, wherein the determined well site deployment region is a well site deployment high-production region of the to-be-developed oil reservoir. A well sitedeployment is accurately guided by adopting the preset well site deployment strategy, the well site deployment is carried out on the determined well site deployment region, the well drilling success rate can be increased, the single well benefit is guaranteed, the well site deployment accuracy is effectively improved, and the well site deployment risk is reduced.

Description

technical field [0001] The invention relates to the technical field of oilfield development, in particular to a method, device and storage medium for determining a well location deployment area. Background technique [0002] In the process of reservoir exploration and development, well location deployment is an extremely important key link, which directly affects the success or failure of exploration and the long-term stable production of the reservoir in the later stage. Therefore, scientifically providing the optimal well location deployment area plays a pivotal role in reservoir exploration and development. For carbonate reservoirs, due to their strong heterogeneity, deep burial (greater than 4,500 meters), and complex oil and gas accumulation rules, it is more difficult to determine the well location deployment area. [0003] In the existing technology, for carbonate reservoirs, the well location deployment area is often determined by combining the oil source fracture s...
