在钻探生产施工中，工程技术人员、统计人员要对施工中的钻孔或完工的钻孔进行纯钻时间及进尺数据的统计分析与综合整理。用计算程序可以把所有计算数据都存入计算器内，随之可以求出九个数据来，即：（1）纯钻时间；（2）总进尺；（3）总台时；（4）小时进尺；（5）回次数；（6）平均回次进尺；（7）平均回次时间；（8）台月数；（9）台月效率。用这种方法进行计算，简单，容易掌握，计算实例如下表。运算：操作步骤首先将工作开关拨至STAT，选择开关。注：计入台月的总台时=F∑_x+M
In the drilling production and construction, engineering technicians and statisticians should carry out statistical analysis and comprehensive arrangement of the time of pure drilling and the footage data of the drilled or completed drilling in construction. All calculations can be stored in the calculator using the calculation program, followed by nine data can be obtained, namely: (1) pure drilling time; (2) the total footage; (3) the total station time; (4) (5) the number of times back; (6) average back footage; (7) the average time back; (8) Taiwan month number; Calculated in this way, simple, easy to grasp, the calculation examples in the table below. Operation: Operation steps First, set the working switch to STAT and select the switch. Note: The total station count in Taiwan month = FΣ_x + M
