n: a metering instrumentation system component mat counts me revolutions of me index shaft.

n: a meter index that has a pressure correction factor built into the gear ratio of the dial.

n: Reflects flow behavior of liquid.

n: an exponent to evaluate the drillability of rock

n: the index including drilling speed,unit yardage cost,well devitation, core recovery,qualification rate of well cementation,production efficiency and so on ,used to idicate the drilling reslut-characters of a well,a rig or a facility qualitatively and qua

n: the periodic or noncyclic written material used to summarize the drilling index and kinds of pace curve ,and list new equipments and technique and also analyse the drilling problems

n: a index to react the drilling efficiency which can be expressed by the formula :drilling speed per run = (drill footage)/〔net drilling time+ round trip time〕

n: analyse and evaluate the situation of abrasion of the used bit (tooth, bearing and diameter),working index,and drilling parameters to offer reference to bit selection for next well or
next hole section

n: a quality index of drilling fluid ,namely the liquidoid qantity of fluid filtered in the porosity layer under the effect of pressure difference
