摘要
国内常规拖挂钻机普遍采用2段伸缩式结构,由于运输尺寸限制,通常井架的高度较低,多数产品只适用于19 m立根作业,不满足北非用户的使用要求。为此,研发了ZJ40DBT沙漠快速移运拖挂钻机。该钻机采用5轴传动结构,将自动送钻系统和主电机动力输入系统集成在一台减速器上,既减小了绞车宽度,又简化了传动结构;井架采用直立无绷绳3段伸缩式结构,满足28 m立根作业要求。厂内和现场试验结果表明:钻机的各拖车移运平稳,刹车灵敏,泵的各项指标满足要求;钻机能实现快速安装和移运功能,各项技术参数满足钻井作业要求。该钻机的研制成功为成套钻机的快速移动设计积累了经验。
At present,the dual-section telescopic structure is widely used in the trailer rig. Due to the low height of the derrick limited by the transportation,the majority of the products are only suitable for 19 m stand operation and do not meet the requirements of North African users. In view of this,Model ZJ40 DBT desert fast moving trailer rig has been developed. The rig adopts a 5-axis drive structure,and integrates the automatic drilling system and the main motor power input system in a reducer,so as to reduce the drawworks width and simplifies the transmission system. The mast is a triple-section telescoping upright type mast without guy line,which meets the 28 m stand operation requirements. The results of the factory and field tests show that the trailers of the rig moved smoothly,the brakes were sensitive,and the indexes of the pumps meet the requirements. The drilling rig can realize quick assembly-disassembly and transportation function,and all of the technical parameters meet the drilling operation requirements. The successful development of the rig has accumulated experiences for the fast moving of full set of rig.
