Abstract

This numerical study was undertaken to investigate and compare the performance of polymer flood processes through different combination of horizontal and vertical wells for injection and production. IMEX, the three-dimensional numerical reservoir model of Computer Modeling Group, is used to analyze the performance of the reservoir. The potential for a horizontal well application was assessed through different scenarios in combinations of injection and production wells and reservoir area and thickness. For different parameters of the reservoir system, performances were compared in terms of cumulative oil recovery and water-oil ratio at the production well and bottomhole pressure or injectivity at the injection well. Results from the study have demonstrated that additional oil can be recovered and injectivity was significantly improved by utilizing a combination of horizontal wells when the same multiple constraints are assigned for injection and production wells. The improvement of injectivity through then horizontal injection well was higher when it was combined with horizontal producer. Properties of polymer and reservoir rock such as reservoir thickness and well spacing are also shown to impact the predicted injectivity.

본 수치 연구는 수평정과 수직정을 주입 또는 생산에 이용한 폴리머 공법 프로세스의 수행을 비교하기 위한 것이다. Computer Modeling Group의 3차원 저류층 시뮬레이터인 IMEX를 사용하여 저류층 수행을 분석하였다. 서로 다른 주입-생산정 조합과 저류층 면적 및 두께에 대한 시나리오를 통하여 수평정 적용의 가능성을 평가하였다. 서로 다른 인자들을 적용한 저류층 시스템에 대하여 생산정에서의 누적 오일 회수량과 물-오일 비, 주입정에서의 공저압력 또는 주입도를 비교하였다. 본 연구의 결과에 따르면 복수의 제한 조건이 주입 및 생산정에 설정되었을 때 수평정을 이용하면 주입도가 현저하게 개선되었다. 수평 주입정을 수평 생산정과 함께 사용하면 주입도는 더욱 개선되고 오일 회수량이 증가한다. 정 간격, 저류층 두께 등의 저류층 특성도 주입도 예측치에 영향을 미친다.
