Abstract

Sucker rod pump (SRP) merupakan metode pengangkatan buatan yang digunakan untuk meningkatkan produksi sumur minyak. Kinerja SRP dipengaruhi oleh berbagai faktor, termasuk gerakan pompa, gaya yang bekerja pada batang penggerak, dan kondisi sumur. Penelitian ini bertujuan untuk menganalisis kinerja SRP menggunakan pendekatan motion simulation dan analisa kinematika dinamika. Penelitian ini dilakukan dengan simulasi komputer menggunakan perangkat lunak Solidworks Simulation. Hasil simulasi menunjukkan bahwa gerakan pompa dan gaya yang bekerja pada batang penggerak memiliki pengaruh yang signifikan terhadap kinerja SRP. Gerakan pompa yang tidak seragam dapat menyebabkan peningkatan beban pada batang penggerak, yang dapat mengurangi umur pompa. Gaya yang bekerja pada batang penggerak juga dapat menyebabkan terjadinya fatigue, yang dapat menyebabkan kerusakan batang penggerak. Penelitian ini memberikan pemahaman yang lebih baik tentang kinerja SRP. Hasil penelitian ini dapat digunakan untuk meningkatkan kinerja SRP dan memperpanjang umur pompa.

Abstract

The falling ball method, based on Stokes law, is a simple yet accurate technique for determining fluid viscosity, though its precision is influenced by factors such as wall, Reynolds, end, memory, and off-center effects. This study aims to determine the effect of spherical geometry on the fluid viscosity value represented by the sphericity factor . An experimental study was conducted to examine its accuracy of viscosity values to produce the correction factor. The sphericity factors studied were 0.993, 0.976, and 0.949. To reduce the uncertainty caused by the wall effect, the ratio db/Dt was 0.071, using a 5.8mm diameter plastic ball and SAE 40 oil fluid at 32.4°C. Terminal velocity (??) was obtained by analyzing the video of the ball falling in the fluid, which was displayed on the tracker software. The video was taken using a 1080p, 60 fps camera. Wall and Reynolds effect correction factors were used to amend experimental viscosity values. The result indicates the viscosity will be accurately determined by selecting a larger sphericity value of the ball during the experimental process. It will reduce the necessity of correction factors to obtain the value of fluid viscosity.
