On December 27, the reporter learned from the Changqing Exploration Area of Oriental Geophysical Exploration that the operation team of Changqing Geophysical Exploration Branch deepened the application of intelligent exploration technology in construction, and the exploration and production increased by 15% compared with the same period last year.
Since the beginning of this year, Changqing Geophysical Exploration Branch has vigorously promoted the research of intelligent exploration technology in view of a number of technical problems such as the difficulty in the layout of excitation points in dense obstacle areas, and continued to promote the speed and efficiency of exploration and production.
In the construction of the Qingyang 3D project, the largest project in the urban area of the Ordos Basin, the operation team faced the problems of multi-faceted and wide obstacle points, low signal-to-noise ratio and high gun path density at the beginning of the pick-up, and the pick-up workload increased by 2 compared with the past4 times. In response to the practical problems, the operation team promoted the in-depth application of Timer software, innovated artificial intelligence AI training methods, established a learning process that was easy first and then difficult, used GeoEast software to automatically pick up the static correction amount of wellgun data, gave priority to completing wellgun training, and used the detection point calibration of wellshots to correct the vibrator, shortened the sample training time by 20%, and achieved a year-on-year reduction of more than 40% in pick-up personnel through technological innovation and software deepening application, and greatly improved work efficiency.
Focusing on the construction problems such as the picking up of obstacles and the huge workload of gun point design, Changqing Geophysical Exploration Branch and the collection and technical support center of Dongfang Geophysical Exploration Company jointly carried out research on intelligent identification technology of ground objects. For the first time, LiDAR aerial survey data was used to promote the fine design of excitation points, and Airborne LiDAR technology was used to form DOM high-definition images and point cloud digital elevation model data during the aerial survey process, and high-precision DEM and DSM raster data were formed through calculation and conversion. Indoor personnel use ArcGIS Pro and Globla Mapper software to load aerial high-definition images and elevation model data to generate three-dimensional modelsThe fine optimization design of the excitation point was carried out to reduce the risk of field operation, improve the rationality of the design of the excitation point, and effectively improve the efficiency of the survey.
Changqing Geophysical Prospecting Branch closely follows the exploration and deployment of oilfield companies, and vigorously promotes the application of T-D-E curve supporting intelligent first-class team system. In view of the goal orientation, the technical personnel focused on the two directions of narrowing the acquisition interval and extending the acquisition time, innovated and refined the "T-D-E rule" for the energy changes of different excitation factors, and scientifically allocated the collection resources. Through technical empowerment, the collection interval was further compressed, and the efficient operation of the project was continuously promoted. The average daily production efficiency of three key projects such as Qingyang 3D reached 3,615 guns, and the production efficiency increased significantly compared with the same period last year.
