Abstract
Pada proses pengeboran bawah air, drill pipe digunakan sebagai media penyambung antara Top Drive dengan drill bit. Drill pipe dengan panjang sekitar 10 m disusun bertingkat dengan sambungan berupa ulir. Pada saat proses pengeboran, drill pipe akan diputar dengan torsi tertentu agar drill bit ikut berputar dan menggesek formasi. Pada saat proses pemberian torsi tersebut, terdapat kemungkinan rusaknya sambungan-sambungan antar drill pipe. Dengan mensimulasikan proses tersebut menggunakan metode Elemen Hingga, dan memvariasikan parameter-parameter drill pipe, didapatkan respons simpangan paling kecil di node 1 pada variasi diameter drill pipe 5,875” sebesar 0,0711 rad pada kondisi Spudding In dan sebesar 0,00355 rad pada kondisi Drilling.

In underwater Drilling, Drill Pipes are used as a connecting medium between Top Drive and Drill Bit. 10 m length Drill Pipes are arranged via threaded connection. During the process of drilling, drill pipes will be given a certain amount of torque so that the drill bit will follow the rotation and rub the formation. At the time of torque given, there is a possibility of damage at the connections between the drill pipe. By simulating the process using Finite Element methods, and varying the parameters of drill pipe, it is obtained that the smallest displacement responses of node 1 is in the 5.875" diameter variation with value 0,0711 rad in Spudding In condition and 0,00355 rad in Drilling condition.
