North China Oil and Gas: UAV aerial photography helps smart oilfield construction

China Petrochemical News Network News "The keyboard operator checks the computer connection, the technician checks the route planning, the operator checks the wing installation, the crew checks the oil movement.

In order to accelerate the implementation of the company’s "three-step" plan, we will do a good job in natural gas exploration breakthroughs in Fuxian County, strive to achieve the core goals of major breakthroughs and major discoveries, comprehensively consolidate basic research on exploration and development, and vigorously promote the optimized implementation of scientific and technological projects.

Technology leads platformization

The Fuxian Exploration Area is located in Fuxian County, Ganquan County, Baota District, Yichuan County, Luochuan County, and Huangling County in Shaanxi Province, with huge resource potential.

Currently, the images and elevation data used in the Fuxian Exploration Area are generally Google Earth Shadow, satellite remote sensing images, etc.

In order to ensure the smooth development of the aerial photography project, the branch attaches great importance to it, and the North China Branch of Sinopec Geophysical Company is responsible for the completion of the construction tasks.

The project uses the SmartGIS Web3D three-dimensional platform as the basis to build a GIS application platform for aerial survey data in the Fuxian exploration area, which integrates geological attribute data, exploration and development data, ground digital elevation models, high-definition images and ground object data, and multi-source three-dimensional model data.

Efficient exploration and development

The comprehensive collection of high-precision aerial photography, 3D seismic and comprehensive geophysical data provides strong support for the subsequent planning, construction, test operation and maintenance of the integrated intelligent well site, which can effectively improve the oil and gas reservoirs.

Using the high-definition aerial survey results data combined with the geological outcrop map, the outcropping range of the main target layer of the geological mapping, the main lithology and the distribution of the main faults in the study area are made fine statistics.

In drilling engineering, detailed geographic information is provided for site selection, relocation route and construction method design, earthwork calculation, and work efficiency is improved; when oil and gas pipelines are designed and laid, complex and unsafe areas can be avoided to improve construction quality , Efficiency and effectiveness.

The construction of the station needs to consider various factors such as power supply, water supply, transportation, sewage treatment and construction of the station.

In major dangerous areas, such as coal, oil, and gas mixed mining areas, it is very important to distinguish between various mining areas to achieve cross mining to ensure construction safety.

Above ground and underground integration

With the goal of building a three-dimensional integrated intelligent oil field of air, ground, and deep, combined with the current exploration and development status of the Fuxian block, using high-definition aerial survey results and geophysical and seismic exploration of the entire reservoir element data to organically combine to achieve Fuxian The block provides three-dimensional seismic and comprehensive geological exploration of the entire reservoir element data, laying a data foundation for subsequent exploration and development work.

Break the horizontal division of oil fields and establish a ground-and-underground integrated environment for decision-making, management, and operation.

Gather the oil field information into a three-dimensional oil field scene, display the basic situation and information of the integrated oil field, and display the integrated above-ground and underground overall model.

As the main geospatial information data, aerial survey results are combined with the GIS system to form a basic geographic information data platform, combined with oilfield exploration, development, equipment, safety, production, management and other data to form integration of exploration and development, integration of management and control, and ground Underground integration, a smart oilfield integrated platform capable of comprehensive perception, prediction optimization, integrated operation, and automatic control.
