摘要
DZ315整体起升底座是用绞车动力整体起升的平行四边形底座。这种底座结构简单,制造容易,费用低,整体刚性好,运输安装方便,起放安全可靠,单位井深的底座重量小,设计负荷符合GB1806—86和API Spec 4F的规定。底座底面至转盘梁底面净高6.15m,钻台高7.5m,用于电驱动中深井钻机经济效益较好,为设计高底座提供了经验。
DZ315 Derrick Substructure is parallelogram shaped, light,simple and rigid structure. It can be errected by drawworks ofdrilling rig safely. Load capability conforms to GB1806--86 andAPI Spec 4F. It is especially applicable to drilling rigs withdeep-and mid-deep-well drilling capability
