塔拉拉油田第六区块钻头使用分析及选型

Bits Behavior Analyses and Selection in NO.1 Block of Talara Oilfield

根据塔拉拉油田第六区块的地层特性和该区块６口井钻头使用分析，应用钻井成本方程求出各种钻头在同一层段的单位进尺成本。通过对比分析，优选出适合于该区块的钻头类型。

According to the formation characteristics and bits application analyses of 6 wells in the area, unit drilling costs of various bits at the same interval are calculated with drilling cost equation. Through comparative analyses,suitable types of bits for the area are selected.
