On January 27, the reporter learned from the Liaohe Exploration Area of Oriental Geophysical Exploration that the three-dimensional exploration project in the Niuju area of the eastern sag of the Liaohe depression undertaken by the 2269 team of the Liaohe Geophysical Exploration Branch has been efficiently completed recently.
The three-dimensional exploration project in the Niuju area of the eastern sag of the Liaohe depression is the first three-dimensional exploration for shallow, medium and deep multi-layer targets since the exploration of targets in the Liaohe depression. The project covers an area of 300 square kilometers, implements the integrated exploration technology of "two widths and two heights", and adopts EV56 high-precision vibrator excitation and ultra-high sensitivity geophone reception. Liaohe Geophysical Prospecting Branch scientifically formulates production and operation plans, upgrades resource allocation in an all-round way, ensures the acquisition of high-quality data, and meets the geological research needs of oilfield companies.
Break through production bottlenecks with "iconic technology". In view of the characteristics of the project with high task requirements, highly strengthened technical solutions, and extremely complex ground surface, the 2269 team adheres to the principle of "integration of collection, processing, and interpretation", and tackles five special technologies, including excitation point optimization and trajectory design technology in complex water network areas. At the same time, we adhere to the guidance of geological needs, and implement specific measures such as point optimization, parameter optimization, and encrypted arrangement in key areas and obstacle areas to ensure the high-quality acquisition of raw data.
Promote collaborative production and operation with "benchmarking management". The 2269 team formulated an integrated operation plan for technology, production and coordination for key obstacle areas, closely connected key production processes such as arranging and reversing, and source acquisition, continuously strengthened team management, and realized the overall coordination and linear command of personnel, vehicles and equipment. The pay-off class implements 24-hour "real-time rolling management + node on-site patrol management", and realizes "air + ground" all-round quality control management through "UAV batch node QC status ** + special person patrol and patrol"; Optimize the layout of artillery points to ensure that the seismic source can be safely and smoothly constructed in densely populated areas.
Achieve high quality and high efficiency of production collection with "standardized process". The 2269 team implements four-in-one collaborative management of technology, production, safety and quality control. Closely combined with the actual situation of the work area and weather changes, in accordance with the safety and quality control requirements of different processes, the quality and efficiency of field operations are steadily improved. With the letter of commitment, task book, and responsibility list as the "yardstick", the "two-way evaluation" of field operators is carried out to comprehensively promote the speed and efficiency of the project.
