| 成果简介 | NOVELTY - Invention relates to geotechnical monitoring of gas production facilities based on the use of a complex of ground and aerospace observations, automation of measurements and remote data transmission and can be used in organizing and conducting geotechnical monitoring at gas deposits. In the method for automated measurements and remote transmission of data for geotechnical monitoring of gas production facilities, radar survey is carried out from a satellite with interferometric data processing by the method of natural permanent reflectors, using optical survey from a satellite, spatial superposition of observation points (natural permanent reflectors) is performed; determining coordinates of points (at a rate of up to 2 million points per second) by measuring angles and distances from the scanner to visible (reflecting) points of the surface of the object with a laser beam and corresponding directions (vertical and horizontal angles) are recorded with subsequent formation of a three-dimensional image (scan) in the form of a point cloud; registration of inclination angles and deformations of surface of structures; performing geometric levelling by deformation marks; data are integrated in the information model of the object, into which all control data are uploaded in formats that comply with the requirements, as well as data on the object are uploaded; plotting curves of displacements/deformations (other parameters) in time according to data obtained during the observation period; performing spatial alignment of control points of different monitoring units using the “nearest neighbour” method in the geoinformation software according to the specified buffering rules of the object; spatial analysis of data both on separate control units, and combined, is performed by methods of: classification of values through specified intervals and surface interpolation: creation of isolines from point data, construction of surface of distribution of velocities of vertical displacements on object; creating cross-plots of dependencies of data obtained in RCU (SO), RCU (TLS) or APCU, and data obtained in BMG: parameter a from parameter b based on obtained attributive data using standard tools of Microsoft excel or using a scatter diagram in geoinformation software; evaluation of observation accuracy by RCU (SO), RCU (TLS), APCU methods is carried out by comparing statistical indicators obtained by these methods during tests under operating conditions and by the classical method – MSGC. USE - Measuring. ADVANTAGE - Increased efficiency of geotechnical monitoring at gas deposits due to reduction of labour-intensive classical observations in manual mode (levelling) and optimization of geotechnical monitoring by integrating ground and aerospace control methods using a measurement automation system and remote data transmission. 1 cl, 5 dwg |
