description The embodiment of the invention provides a river profile form modeling method based on trend constraint, and aims to solve the problems that during modeling through sedimentary facies or sand-to-ground ratio constraint in a traditional modeling method, a sand body is in abrupt contact at a mudstone and sandstone facies boundary and is represented as a vertical boundary on a profile, the internal form of the reservoir sand body is difficult to represent, and the modeling efficiency is low. And the reliability is poor. According to the method, a gradient trend surface is established to restrain modeling through a reliable sedimentary facies or sand-to-ground ratio plane graph obtained in geological research, so that the problem of sudden change contact of the riverway boundary in a riverway sand body model is solved, and the riverway profile form is improved, so that the riverway profile form has a geological form and conforms to geological knowledge. The internal structure and spatial distribution of a river c
