钻探工程中如何提高机械钻速、提高钻头进尺,从而降低每米钻探成本,是一个非常重要的问题.这些问题又都紧密地同钻进规程参数联系着. 因此,如何使机械钻速、钻头进尺、每米钻探成本最优地同钻进规程参数联系起来,具有重要的理论意义和实际价值.而在探讨这些技术经济指标同规程参数的联系方面,确定或试验求得这种联系的方法是非常重要的.因此本文拟用二水平全因素试验[即在现有经验资料基础上,根据国家标准或有关规范选取上水平和下水平(二水平)、用所有规程参数皆同时变化
It is a very important issue that how to improve ROP and improve drill penetration in drilling engineering so as to reduce the drilling cost per meter, which are all closely linked with drilling parameters, so how to make ROP, It is of theoretical and practical importance to drill down the drilling cost per meter and to drill the parameters of the drilling process optimally, and to determine or test the way to get the connection between these technical and economic indicators and the parameters of the process Therefore, this paper intends to use two levels of full factorial test [that is, based on the existing empirical data, according to national standards or relevant standards to select the level and the next level (two levels), with all the parameters of the procedure are simultaneously changed
