Embodiment Construction

[0063] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0064] Aiming at the defect that the existing reef reservoir engraving method cannot describe the internal structure (ie the inner structure) of the reef reservoir, the present invention provides a new reef reservoir engraving method. This method comprehensively analyzes the shape of reefs from the four levels of point, line, surface and volume, studies the spatial distribution and internal structure of reefs...

Abstract

The invention discloses a reef reservoir engraving method. The method comprises a reservoir identifying step in which a reef reservoir growth layer is determined on the basis of single well facies analysis; a top-bottom engraving step in which the top-bottom of the reef reservoir is engraved on the basis of the growth layer and according to the seismic section and the wave impedance section of the reef reservoir; a top-bottom constraining step in which a plane growth favorable region of the reef reservoir is acquired according to the reef reservoir form, seismic facies data, sedimentary facies analysis and ancient landform analysis and further used to constrain top-bottom engraving so as to acquire a finely engraved top-bottom; and an internal structure determining step in which the internal structure and the geometric parameters of the reef reservoir are acquired by adjusting visualization parameters to perform visualization analysis on the reef reservoir on the basis of the finely engraved top-bottom. The method which can make the internal structure of the reef reservoir engraved achieves more comprehensive and more accurate engraving of the reef reservoir.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration and development, in particular to a method for carving reef reservoirs. Background technique [0002] Reefs occupy an important position in carbonate oil and gas fields because of their good storage properties, and their oil and gas resources have always been a valuable asset that has attracted worldwide attention. Since the discovery of the first reef-type gas reservoir in the Jiannan Permian system in eastern Sichuan in the 1970s, such reservoirs have been discovered and put into development one after another. focus on. [0003] In recent decades of research, with the continuous development of seismic technology, research on various methods has been carried out for the prediction of reef reservoirs. The current reef reservoir prediction technology mainly includes: reef facies seismic pattern recognition technology, seismic attribute analysis and optimization technology, neural ne...
