A splitting method of gas reservoir single well control area based on artificial intelligence

Abstract

The invention relates to gas reservoir single-well control area splitting method based on artificial intelligence, and belongs to the field of oil-gas reservoir reserve evaluation. In order to solve the problems of larger calculation error and tedious process in calculation of an existing gas reservoir gas well single-well control area, the technical scheme of the gas reservoir single-well controlarea splitting method based on artificial intelligence comprises the steps of first, preparing static and dynamic parameters of a gas reservior and a gas well, and drawing a gas reservoir block boundary curve by using a triangulation algorithm; building a permeability two-dimensional matrix, an effective reservoir thickness two-dimensional matrix and a porosity two-dimensional matrix of gas reservoir properties; based on a diversified competition region growing image segmentation algorithm, calculating a single-well competition coefficient; carrying out intelligent splitting on the gas reservoir single-well control area by combining with the single-well competition coefficient; and obtaining each single-well control area proportion, and calcaulting to obtain each single-well control areaby combining with a gas reservoir actual gas-bearing area. The method is close to practice, and the calculation process is time and effort saving; a single-well control area splitting drawing is drawnby utilizing programming so as to be intuitive in image; and the application range is wide, and the generalizability is high.

Description

technical field [0001] The invention relates to an artificial intelligence-based method for splitting the control area of ​​a single well in a gas reservoir, belonging to the field of reserve evaluation of oil and gas reservoirs. Background technique [0002] Compared with some other general remaining gas research methods, the single well geological reserve calculation method is more and more widely used because of its strong operability in the calculation process and high reliability of the results. In the middle and later stages of oil and gas field development, the purpose of single well geological reserves calculation is to clarify the remaining geological reserves and the distribution of remaining oil and gas on the plane well point, and the calculation of single well control area is the most important thing in the determination of single well geological reserves. The relevant research on the calculation of the single well control area of ​​the gas reservoir is of great...
