Abstract

In case of the paraffin deposition in the producing oil fields, the flow assurance can be deteriorated leading to decrease in production and inefficient field operation. In this study, to inhibit the paraffin deposition in advance, a customized chemical product was developed by blending the chemical components that can interfere the crystalline growth and disperse the paraffin components in crude oil for the Kazakhstan field. The performance of the product was verified using pour point measurement and cold finger test. Futhermore, by optimizing the performance of the inhibitor through flow simulation the complete product was successfully developed displaying over 90% inhibition rate per 1,000 ppm as targeted. The processes of the development and performance evaluation of the customized product for inhibiting paraffin deposition are presented in this study.

생산유전 현장에서 파라핀 침적이 발생할 경우, 유동안정성이 악화되어, 생산량 저하 및 비효율적인 현장운영 등의 문제를 초래하게 된다. 본 연구에서는 카자흐스탄 지역의 유전 현장 시설물에 파라핀이 침적되는 것을 사전에 억제하기 위해, 문제유정의 원유를 대상으로 원유 내 파라핀 성분의 결정성장을 방해하고 분산시킬 수 있는 화학성분을 조합하여 맞춤형 화학제품을 개발하였다. 개발된 제품의 성능은 유동점 측정, cold finger 실험을 통해 검증하였고, 유동모사시험을 진행하며 억제제의 성능을 최적화함으로써, 개발목표치인 1,000 ppm당 90%이상 억제율을 발휘하는 억제제 시제품을 완성하였다. 이에 파라핀의 침적을 억제하는 맞춤형 화학제품의 개발과 성능평가 과정을 기술하였다.
