摘要
钻井工程预算常以标准井为基础，按设计井深与标准井井深的差异大小分段进行调整，这种方法极不合理，在实际应用中误差很大．从统计的观点出发，首次提出了钻井工程预算井深调整系数的概念，并建立了钻井工程预算的基本模型．该方法经实例应用分析表明能极大地提高钻井工程预算的精度，具有一定的科学性和合理性．
At present,the budget(period and cost) of drilling engineering is based on the standard well,and is readjusted segment by segment according to the difference of depth between the designed and the standard wells.That budget method is unreasonable and has great error in actual application.This paper,proceeding from statistics,puts forward the new concept of well depth adjustment factor for drilling engineering budget and established the basic budget models.Practical application examples show that this method can greatly raise the precision of drilling ergineering budget.Being scientific and reasonable,it is expected to achieve good results in actual applicatoins.
