Abstract

Salah satu bahan baling-baling yang banyak digunakan adalah aluminium paduan. Kerusakan propeller yang terjadi di dominasi oleh terjadinya patah pada salah satu atau beberapa daunnya. Kerusakan berupa patahnya propeller tidak hanya disebabkan oleh beban kerja propeller, melainkan sebagai hasil akumulasi antara kerja propeller dan lingkungan kerjanya yang korosif. Salah satu cara meningkatkan sifat mekanis paduan aluminium adalah dengan perlakuan panas penuaan (aging treatment). Penelitian ini bertujuan untuk mendapatkan laju korosi akibat pengaruh kecepatan putaran propeller dan aging. Pada penelitian ini material Al paduan di-aging pada temperatur 170°C selama 180 menit. Material tanpa aging dan hasil aging kemudian diuji korosi dengan metode celup pada variasi putaran propeller 800 rpm, 1000 rpm, 1200, dan 1500 rpm dengan waktu perendaman 12 jam , 24 jam, 48 jam,dan 168 jam. Hasil penelitian menunjukan bahwa kecepatan putaran propeller mempengaruhi laju korosi material. Spesimen yang diputar pada kecepatan 1500 rpm memiliki laju korosi 1,0084 mm/year untuk material tanpa aging dan 0,9447 mm/year untuk material dengan aging. Laju korosi ini lebih besar dibandingkan spesimen yang diputar pada kecepatan 800 rpm, 1000 rpm dan 1200 rpm. Laju korosi pada putaran 800 rpm adalah 0,6472 mm/year untuk material tanpa aging dan 0,5141 mm/year Utuk material dengan aging. Aging yang dilakukan pada material dapat menurunkan laju korosi dari 0,6472 mm/year menjadi 0,5141 mm/year pada putaran 800 rpm, 0,7913 mm/year Menjadi 0,6775 mm/year pada putaran 1000 rpm, 0,8805 mm/year menjadi 7438 mm/year Pada putaran 1200 rpm dan 1,0084 mm/year menjadi 0,9447 mm year pada putaran 1500 rpm.

Abstract

One of the production problems that arise at the Gathering Station is an unstable production problem, this is caused by controlling the level of fluid in the wash tank that is less than the maximum for that need to be improved by changing the system from manual to automatic. To maintain the stability of production at the gathering station, special measures such as controlling fluid levels in the storage tanks need to be carried out, monitoring pressure, temperature monitoring and so on that can have a positive effect on oil production at the gathering station. Wash Tank is a tank that is useful for temporary storage of liquid fluid (liquid) that comes from the boot gas. The liquid fluid entering the wash tank consists of a mixture of crude oil and water. At the Wash tank the process of separation between crude oil and water. This washing tank is the largest tank compared to other processing tanks at the gathering station, its diameter is around 85 ft to 90 ft, and its height is around 35 ft to 40 ft. The normal level in the separation process is 36 ft, where the level 1 ft - 29 ft is the water level, while the level 29 ft - 36 ft is the oil level. The 1ft - 29 ft level is referred to as the interface level, where the water level is expected to be at level 29 and the thickness of the oil / oil stock tank 7 ft in the wash tank. Research conducted on the problem of controlling the level of fluid in the wash tank, where manual control is ineffective and inefficient, for this reason it is necessary to change from a manual to automatic process with the ROC (Remote Operation Control) system, the changes made are expected to maintain the interface and the oil stock tank in accordance with the set point that has been determined and where the amount of oil production per day at the gathering station is very influential on the oil stock tank so that the oil pumped to the shipping line has a BS&W below 1% and has a temperature of 130 ° F -150 ° F In order to obtain this value, we must maintain the interface and the oil stock tank in accordance with the specified set point and where the amount of oil production per day at the gathering station is very influential on the oil stock tank

Abstract

The condition of a well if it is produced continuously will cause reservoir pressure to fall, and the flow rate will also go down, as a result the productivity of the well will also decrease. For this reason, there is a need for energy that can help lift fluid up to the surface. In the primary method there are 2 stages of production, namely natural flow where oil is raised directly through the tubing surface, and artificial lift is the method of obtaining oil by using the aid of additional tools. In the oil industry there are various types of artificial lifts, one of which is an electric submersible pump (ESP). Electric Submersible Pump is an electric pump that is immersed into a liquid. This pump is made on the basis of a multilevel centrifugal pump where each level has an impeller and iffuser which aims to push the fluid to the surface. ESP planning is strongly influenced by the roductivity of production wells. The rate of fluid production influences the selection of pump type and size. This is because each pump has its own production rate based on the type and size of each pump used. In the course of producing oil, there will certainly be a problem that will cause a decline in production, therefore it is necessary to evaluate and redesign the ESP pump, in an effort to optimize the production potential of these wells. In this study an evaluation of the performance of the electrical submersible pump will be carried out and a pump redesigned to optimize production using AutographPC software on the well X in the field Y Kondisi suatu sumur jika diproduksikan terus-menerus akan mengakibatkan tekananreservoir turun, dan laju alir akan turun pula, akibatnya produktivitas sumur akan turunjuga. Untuk itu perlu adanya tenaga yang dapat membantu mengangkat fluida sampaikepermukaan. Dalam metode primer terdapat 2 tahapan produksi yaitu natural flowdimana minyak terangkat kepermukaan langsung melalu tubing, dan artificial liftmerupakan metode perolehan minyak dengan menggunakan bantuan alat tambahan.Dalam dunia perminyakan ada berbagai macam jenis pengangkatan buatan salahsatunya adalah electric submersible pump (ESP). Electric Submersibel Pump merupakan pompa listrik yang dibenamkan kedalam cairan.Pompa ini dibuat atas dasar pompa sentrifugal bertingkat banyak dimana setiap tingkatmempunyai impeller dan diffuser yang bertujuan untuk mendorong fluida kepermukaan.Perencanaan ESP sangat dipengaruhi oleh produktivitas sumur produksi. Laju produksifluida berpengaruh terhadap pemilihan jenis dan ukuran pompa. Hal ini dikarenakantiap-tiap pompa memiliki laju produksi sendiri berdasarkan jenis dan ukuran tiap- tiappompa yang dipakai. Dalam kegiatan memproduksikan minyak tentu suatu saat akan terjadi permasalahanyang mengakibatkan menurunnya produksi, Oleh karena itu perlu dilaksanakan evaluasidan design ulang pompa ESP, sebagai upaya untuk mengoptimalkan potensi produksisumur-sumur tersebut. Pada penelitian ini akan dilakukan evaluasi kinerja electricalsubmersible pump dan melakukan desain ulang pompa untuk optimasi produksidengan menggunakan software AutographPC pada sumur X lapangan y Kata kunci: electric submersible pump, AutographPC, laju produksi
