What's the difference between a casing and a drill pipe

There are two main differences between oil casing and oil drill pipe: 1.2. Different materials.

Oil casing is a steel pipe used to support the oil and gas well walls to ensure the normal operation of the whole well during the drilling process and after completion.Each well USES several layers of casing, depending on drilling depth and geology.Cement should be used after casing goes down well, it is different from tubing and drill pipe, can not be reused, it belongs to one-time consumption material.As a result, casing accounts for more than 70 percent of all well tubing consumption.Casing can be divided into: pipe, surface casing, technical casing and reservoir casing.

A rod connected in a drilling tool to transfer power.Drill string usually consists of drill bit, drill collar, drill pipe, stabilizer, special joint and kelly.The basic functions of the drill string are :(1) pull down the bit;(2) apply drilling pressure;(3) transfer power;(4) conveying drilling fluid;(5) carrying out special operations: cement extrusion, dealing with downhole accidents, etc.

API standard E75 to S135 steel grades with diameters ranging from 2 3/8 "to 6 5/8" and double shoulder joints with high torsion resistance and special steel grades BNK C95S for sour Wells.It is mainly applicable to the construction of deep Wells, horizontal Wells and large displacement Wells in the process of oil and gas exploration and development.
