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 present invention provides a method, device and storage medium for determining a well location deployment area, wherein the method includes: firstly, obtaining the oil source fracture situation of the oil reservoir to be developed, and then, according to the oil source fracture situation of the oil reservoir to be developed and The well location deployment strategy is preset, and the well location deployment area of ​​the oil reservoir to be developed is determined, wherein the determined well location deployment area is a high-yield area of ​​the well location deployment of the oil reservoir to be developed. The present invention accurately guides the well location deployment by adopting the preset well location deployment strategy, and deploys the well location in the determined well location deployment area, which can improve the drilling success rate, ensure the benefit of a single well, effectively improve the accuracy of the well location deployment, reduce the Well deployment risks.

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...
