Abstract

Tubing N80 sering digunakan sebagai production tubing, namun sering dilaporkan sering mengalami kebocoran akibat kontak langsung dengan fluida. Beberapa faktor penyebab kebocoran tubing ini yaitu perbedaan temperatur dan tekanan yang berlebih. Terdapat teknologi terbaru yaitu metode patch repair dengan menggunakan material non-logam, polimer superabsorbent. Polimer yang digunakan adalah Polyacrylamide, yang memiliki sifat unik dalam menyerap dan memelihara aliran fluida bertekanan. Akibat keterbatasan informasi tentang teknologi ini, maka mulai dikembangkan simulasi patch terhadap kebocoran tubing. Dalam penelitian ini akan menganalisis distribusi thermal dan deformasi pada tubing beserta patchnya, dengan temperatur operasi yang berbeda. Pembuatan geometri dan simulasi dilakukan dengan menggunakan software ANSYS Mechanical APDL Release 18.0 berdasarkan metode elemen hingga. Penelitian ini diharapkan dapat membantu industri minyak dan gas mensimulasikan kinerja patch terhadap kebocoran tubing, sebelum dilakukan secara praktik.============Tubing N80 is often used as a production tubing, but it is often reported about leakage because of the directly contact with the fluid. Some of the factors causing this tubing leakage are the difference of temperature and excess pressure. The latest technology is patch repair method using non-metallic material, called superabsorbent polymer. The polymer used is Polyacrylamide, which has the unique properties of absorbing and maintaining the flow of pressurized fluid. Due to limited information about this technology, then we need to develop patch simulation for tubing leakage. In this research, we will analyze the distribution of thermal and deformation on tubing and its patch, with different operating temperature. Geometry and simulation is done using ANSYS Mechanical APDL Release 18.0 software based on finite element method. This study is expected to help the oil and gas industry to simulate the performance of patches for tubing leakage, before being practiced.
