Abstract

This paper describes three chemical-enhanced recovery methods including polymer flood, surfactant flood, and micellar-polymer flood and compares the results with that from waterflood. The comparisons were based on the numerical investigations of a two-well model in a five-spot pattern operating under various injection sequences. UTCHEM, a three-dimensional numerical model for fluid flow and mass transport, is used to analyze the performance of the reservoir. This study places an emphasis on the design and reservoir parameters including slug design, oil viscosity, and initial oil saturation which are known to influence the efficiency of chemical floods. Results for the four processes are compared and contrasted, showing that on the basis of oil recovery, the types and sequence of injecting fluids were shown to impact the predicted recovery. Micellar-polymer flooding was shown to recover a large fraction of the remaining oil, especially in reservoir with residual oil saturation. It is noted that although an increased recovery is obtained with polymer or micellar-polymer flood in unfavorable mobility conditions, the significant increase in the amount of pressure drop at the injection well may make the application impractical.

본 연구에서는 5점 패턴 내 2정 모델에 대하여 적용된 폴리머 공법, 계면활성제 공법, 미셀-폴리머 공법 등 세 종류의 화학 증진 회수 기법을 설명하고 수치 연구의 결과를 수공법의 결과와 비교하였다. 저류층의 거동을 분석하기 위하여 유체 유동과 질량 이동에 대한 3차원 수치 모델인 UTCHEM을 사용하였다. 화학공법의 효율에 영향을 미치는 슬러그 설계, 오일 점도, 초기 오일 포화도 등 설계 및 저류층 인자들의 영향을 중점적으로 분석하였다. 네 가지 프로세스에 대한 계산 결과에 따르면 주입 유체의 유형과 배열이 오일 회수에 큰 영향을 미쳤다. 전반적으로 미셀-폴리머 공법을 이용할 경우 회수율이 우수했으며 잔류 오일 포화도 상태의 저류층에서도 잔존 오일의 상당량을 회수할 수 있었다. 불리한 유동도 조건 하에서 폴리머 공법 또는 미셀-폴리머 공법을 이용할 경우 오일 회수가 증가하였으나 주입정의 압력 강하량이 급격히 증가하므로 적용에 한계가 있을 수 있다.
