摘要
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。
The supply power is a key issue in distributed fully-digital seismic exploration instruments which are indispensable for oil and gas exploration. A storage battery power supply system was developed that greatly extends practical applications for such instruments. The power supply was evaluated using a numerical model and experimental tests. The results show that the power supply can supply 56 or 40 geophones when the distance between two geophones is 55 or 80 meters. In practice, this is enough to meet the demands of distributed fully-digital seismic exploration instruments.
