钻井是石油天然气勘探开发的重要手段,全球每年用于石油天然气勘探开发总投资超过5000亿美元,其中钻井投资占石油天然气勘探开发总投资的60%以上,钻井成本高低直接关系到油田勘探开发的综合经济效益,具有举足轻重的地位。正如本期案例提出的,强化油气田工程造价管理的关键是能够在有效控制工程成本的基础上提升企业利润。因此“在石 Drilling is an important means of oil and gas exploration and development. The global annual total investment for oil and gas exploration and development is over 500 billion U.S. dollars. Drilling investment accounts for over 60% of the total investment in oil and gas exploration and development. Drilling costs are directly related to the exploration and development of oil and gas fields Comprehensive economic efficiency, has a pivotal position. As the current case puts forward, the key to enhancing the management of oil and gas field construction costs is to raise the profit of enterprises based on the effective control of construction costs. Therefore ”in the stone
