| 摘 要： | 影响钻探设备寿命长短的因素,不仅是钻探设备的自然寿命问题,更重要的是钻探设备的技术寿命和经济寿命问题。自然寿命是设备更新的基础,技术寿命和经济寿命是设备改造与更新的核心。钻探设备一次性投入费用与年度维持费的总和达到最小值为设备更新的最佳方案。通过计算可确定钻探设备的最佳更新期。

| Abstract: | The problem that the life of drilling equipment is long or short is not only concerned with thenatural life of drilling equipment but also concerned with their technical and economic life.The natural life ofdrilling equipment forms the basis of their renewing.Besides,the technical and economic life of drilling equip-ment is the key to their reforming and renewing.The author recommends that the best plan for reforming andrenewing drilling equipment is to let the total costs of drilling equipment investment and annual support fee reachminimum value.And the best renewal time of drilling equipment can be determined by the way of calculating. |
