SY 5541-92
This standard specifies the classification of work areas, seismic drilling shift quotas and daily labor quotas for exploration teams in mountainous areas. This standard applies to two-dimensional or three-dimensional exploration teams in mountainous areas where seismic instruments, drilling rigs and other production equipment and daily supplies are transported by manpower or animal power during the production process.
2 Basic requirements
2.1 This standard is based on a certain dynamic staffing. When implementing this standard, it is necessary to cooperate with the current staffing standards, see Appendix A (reference). 22 The exploration area must be strictly classified according to the geomorphic features and seismic geological conditions specified in Table 1 to ensure the accurate implementation of this standard. 2.3 According to the seasonal surprise construction of the seismic team, centralized and integrated In view of the characteristics of the work, this standard stipulates that the daily quota on-site working time of the team is 540min. 2.4 Due to the complex lithology and supplementary blasting in mountainous areas, the number of drilling rigs shall be calculated based on the team's annual total drilling work expectation of 5%. 2.5 The labor quota of the three-dimensional seismic team in mountainous areas is based on the "strip method" construction. According to the two observation systems of "middle" and "bilateral" blasting, the non-vertical distance is divided into 5 levels, with the minimum non-vertical distance as 1, and the coefficient is progressively increased by 5%. The specific construction parameters and various time parameter values ​​of the two-dimensional seismic team in mountainous areas are used to compile the three-dimensional team's daily labor quota. 2.6 The labor quota of the three-dimensional seismic team in mountainous areas, when the reflection surface elements are the same and the number of coverage in the non-longitudinal direction (n) is the same, the number of longitudinal coverage (n) is based on 4 times, and each increase is Or decrease by 1 time: the labor quota is increased or decreased by 5%. 3 Work area classification
The classification of work areas is shown in Table 1.
Table 1 Classification of work areas
Landform and geological conditions
The mountain outcrop layer is mudstone, which is easy to drill. The relative height difference of the terrain is less than 100m, and good seismic data can be obtained. When the seismograph is installed, you can stay in the car
The outcrop layer is the Paul or Belarusian stratum, the relative height difference of the terrain is less than 200, and the drilling is relatively weak. A section can obtain good seismic data
The Jurassic or Belarusian stratum is exposed, and a large area of ​​Quaternary sediments covers the gravel area. Some quartz areas and other filter sand layers are distributed in patches. The terrain height difference is greater than 200m. Less than 400m, whether there are forests (bamboo forests) or shrubs is approved by the Ministry of Energy of the People's Republic of China on 1993-02-22. The representative should be

Yunnan, Fuyuan
The top of the exposed Triassic Upper System strata, the Paulian Artesian System and its underlying strata are divided into: Although the exposed strata are Jurassic and Cretaceous strata, the relative height difference of the terrain is greater than 400m and less than 600m. There is a large area of ​​forest (bamboo forest) or shrub cover, and geological data can be obtained. The exposed carbonate rock has certain water-bearing conditions, and the width of the carbonate rock is generally not large. Although there is no carbonate rock exposed, the relative height difference of the terrain is greater than 600m and less than 1G00m, with Cretaceous gravel layers in between. , covered by forest (bamboo forest) or shrubs, seismic data can be obtained
