On December 25, the author was informed that the three-dimensional field acquisition task of the deep shale gas exploration project in the Sichuan Basin - Zi 201 well area, undertaken by the Oriental Geophysical Exploration Southwest Geophysical Exploration Branch, was successfully completed recently.
Located in the central part of the Sichuan Basin, the construction area of the 3D project in the 201 well area is 193429 square kilometers, covering an area of 680 square kilometers, involving 38 towns and villages in 2 cities, 4 districts and counties of Ziyang and Neijiang, is an important project for the southwest oil and gas field to finely characterize the structure and fault characteristics of the Zi201 well area, implement the distribution and potential of shale gas resources in the Xiaozhusi Formation, and support the next step of the proven reserves in the area.
Focusing on the goal of building a deep shale gas exploration demonstration project in the basin, the geophysical exploration team of the Southwest Geophysical Exploration Branch, which undertakes the field collection and construction, has laid a system guarantee and organizational foundation for the construction to speed up and improve efficiency with the measures of "fine and simultaneous development, five optimizations, efficient organization, and six improvements". Southwest Geophysical Prospecting Branch has invested more than 600 sets of drilling rigs and more than 40,000 pieces of various collection equipment.
Since the beginning of the collection in early November, the Southwest Geophysical Exploration Branch has carefully organized and dug deep into the potential of speed and efficiency improvement, studied intelligent technology and standard processes, optimized the observation system, optimized the excitation parameters and reception conditions through the experimental gun, and simultaneously solved the difficulties of geological tasks and acquisition, and the field collection exceeded 2000 guns per day, laying a solid foundation for the efficient completion of construction tasks.
