Abstract

Pada industri pengeboran minyak, gas, dan geothermal dibutuhkan perlatan mekanikal pompa yang digunakan untuk mensirkulasikan drilling fluid. Drilling fluid atau sering dikenal dengan lumpur (mud) pada operasi pengeboran merupakan faktor yang penting. Ketika proses pengeboran berlangsung, mata bor (bit) yang digunakan akan menggerus formasi tanah dengan laju tertentu atau rate of penetration (ROP) yang menghasilkan serbuk potongan tanah dan batuan formasi yang dikenal dengan cuttings. Semakin dalam suatu operasi pengeboran , maka semakin besar tekanan dan cuttings yang dihasilkan akan semakin banyak. Agar proses pengeboran berjalan lancar dan rangkaian drill string tidak terjepit, maka cuttings perlu diangkat ke permukaan dengan sempurna. Karena itu perlu sebuah peralatan mekanikal pompa yang dapat mensirkulasikan suatu fluida (drilling fluid) dari permukaan sampai kembali ke permukaan melewati rangkaian drill string dan sumur. Pada perancangan ini didasarkan oleh kedalaman sumur yang dibor dan kapasitas yang dibutuhkan. Selanjutnya dihitung besar dari kerugian tekanan (head loss) yang terjadi sepanjang sistem sirkulasi fluida untuk didapatkan daya minimum pompa. Hasil yang didapatkan pada perancangan ini adalah daya yang dibutuhkan sebesar 1500 HP, kapasitas 848 gpm dengan diameter liner 7 in, stroke 11 in, dan efisiensi 96%. Kemudian konstruksi connecting rod dengan diameter 10.62 in dan 28.7 in, diameter main shaft pada crankshaft 10.23 in, dan valve yang digunakan menggunakan standar API #6. ====================================================================================================================================================================================
In the oil, gas and geothermal drilling industry, mechanical pump equipment is needed to circulate drilling fluid. Drilling fluid or often known as mud in drilling operations is an important factor. When the drilling process takes place, the drill bit used will erode the soil formation at a certain rate or rate of penetration (ROP) which produces powdered pieces of soil and rock formations known as cuttings. The deeper a drilling operation, the greater the pressure and the more cuttings produced. So that the drilling process runs smoothly and the drill string is not stuck, the cuttings need to be lifted to the surface properly. Because of this, we need a mechanical equipment pump that can circulate a fluid (drilling fluid) from the surface to return to the surface through a series of drill strings and wells. This design is based on the depth of the well drilled and the capacity required. Next, calculate the amount of pressure loss (head loss) that occurs throughout the fluid circulation system to obtain the minimum pump power. The results obtained in this design are the required power of 1500 HP, capacity of 848 gpm with a liner diameter of 7 in, stroke of 11 in, and efficiency of 96%. Then construct the connecting rod with diameter of 10.62 in and 28.7 in, the diameter of the main shaft on the crankshaft is 10.23 in, and valve used uses API #6 standard.
