Geographical representativeness description Sichuan basin
Reference year 2022
Name
Regional exploration ; Favorable oil and gas bearing zone ; Geophysical and geochemical exploration survey
Use advice for data set Users should apply this data in the context of regional geological surveys and exploration activities, accounting for advancements in theories of gas formation and exploration technologies. Methodological advice includes immediate evaluation of gas reserves upon discovery, precise component analysis of natural gas, and adjusting exploitation plans based on target area conditions. Users should also consider recent technological developments in virtual exploration and remote sensing when interpreting the data. It is essential to incorporate the pressure conditions of reservoir fluids, specifically in contexts similar to the development of shale gas in Sichuan Basin.
Technical purpose of product or process This dataset represents the process of regional exploration and identification of favorable oil and gas bearing zones, focusing on comprehensive geophysical and geochemical exploration surveys. Its practical application is typically limited to the oil and gas industry, where it is used to inform decisions about locating and evaluating potential regions for exploratory drilling and subsequent development of gas fields, such as those found in the Sichuan Basin.

Data selection and combination principles From the beginning of the 20th century to the 1980s, the theory of gas formation in China mainly stayed at the stage of oil generation, and the theoretical cognition at this stage limited the possibility of discovering gas reservoirs under more conditions for Chinese researchers
Deviation from data selection and combination principles / explanations None
Data treatment and extrapolations principles After proving the location of the gas field or drilling natural gas, the natural gas reserves in the target area should be evaluated immediately. Based on the accurate composition analysis of the extracted natural gas, the prediction and evaluation results of natural gas reserves and related subsequent exploitation schemes are optimized according to the conditions of the target area

Data source(s) used for this data set
Sampling procedure Virtual exploration technology based on big data and supercomputing, measurement and control remote sensing technology of satellites and high-altitude unmanned aerial vehicles, etc., have played an important role in the exploration of land-based and sea-based gas fields in recent years. At the same time, the above technologies also provide strong support for proving the growth mechanism of natural gas, such as helping to prove that the key to the development of shale gas in Sichuan Basin lies in the high pressure of reservoir fluid. At the same time, the rapid development of geophysical technology also provides key technical support for the exploration, development and research of natural gas in China
