Embodiment Construction

[0043] 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.

[0044] At present, the tracking results of geological horizon tracking technology are usually multiple geological horizon fragments. If you want to outline a complete geological horizon plan, you need to manually connect these geological horizon fragments, which is a heavy workload and low efficiency.

[0045] Since each geological horizon segment is composed of a plurality of discrete points, the present inv...

Abstract

The invention discloses a geologic horizon fragment automatic combination method. The method comprises the following steps: a regression linear calculation step, i.e., calculating a regression line of discrete points in geologic horizon fragments; a sector scanning area arrangement step, i.e., arranging a sector scanning area with an radius of r and an angle of beta by taking a point on the regression line as a circle center; and a sector scanning area scanning step, i.e., scanning the sector scanning area: if the discrete points of adjacent geologic horizon fragments are scanned, connecting tail-end discrete points of the geologic horizon fragments with the scanned discrete points so as to combine the two geologic horizon fragments. By using the method provided by the invention, the geologic horizon fragments can be automatically combined, and the efficiency of making a geologic horizon plane is improved.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a method for automatic combination of geological horizon segments. Background technique [0002] Velocity and density are the main physical properties of geological rock formations. When the physical properties of two adjacent geological rock formations are significantly different, the contact surface of two geological rock formations is a geological horizon. In the process of geological exploration, the geological horizon tracking technology is usually used to trace the geological horizon and make a plan, and the distribution range and shape of the geological horizon can be learned according to the plan. [0003] The geological horizon tracking results of the current geological horizon tracking technology are usually many geological horizon fragments. If you want to outline a complete geological horizon plan, you need to manually connect these geological horizon fragments,...
