Description
技术领域
本实用新型涉及油气压裂技术领域，具体涉及一种压裂的井场布局***。
背景技术
在全球的油气田压裂作业现场，传统压裂设备所采用动力传动***的配置方式都是柴油发动机连接变速箱经传动轴驱动压裂柱塞泵工作，也就是说，动力源是柴油发动机，传动装置是变速箱和传动轴，执行元件是压裂柱塞泵。常规柴油机驱动，存在一些缺点，比如功率小，体积大，井场布置复杂，噪音大，废气排放，燃油费用高等问题。因此陆续的有电驱压裂设备使用代替了现有的常规柴油驱动，但是现有的电驱压裂井场供配电***配置复杂，走线多，接线耗费时间多；电驱压裂设备输出功率小，为满足井口压裂功率的需求，往往需要在井场布置大量的电驱压裂设备，大量的电驱压裂设备也一定程度上加重了供电接线的复杂化。
实用新型内容
