分布式全数字地震勘探仪器是重要的油气勘探设备,配套电源是其关键设备之一。研制了一种采用蓄电池供电的分布式全数字地震勘探仪器电源系统,该电源系统可根据地震勘探仪器现场铺设需求进行扩展,扩展规模不受用电设备数量及供电范围的影响。对电源系统的供电能力进行了数值计算与试验验证。结果表明:该电源系统在55m、80m道距时,分别具备56道、40道的带道能力,能够满足分布式全数字地震勘探仪器的电源配套需求。
Distributed all-digital seismic exploration instrument is an important oil and gas exploration equipment, power supply is one of its key equipment. A battery-powered distributed all-digital seismic power supply system was developed. The power supply system can be expanded according to the requirements of laying the seismic prospecting equipment. The scale expansion is not affected by the number of electrical equipment and the power supply range. The power supply capability of the power system is numerically calculated and experimentally verified. The results show that the power supply system has the capacity of 56 and 40 channel at 55m and 80m track respectively, which can meet the power supply requirements of distributed all-digital seismic exploration equipment.
