Áp dụng các phương pháp nâng cao hệ số thu hồi dầu (EOR) cho các mỏ dầu khí luôn tiềm ẩn nhiều rủi ro về kỹ thuật và kinh tế do các dự án EOR chịu ảnh hưởng của nhiều yếu tố như: cấu trúc vỉa chứa, thành hệ, tính chất địa chất, thông số công nghệ mỏ, công nghệ khai thác, công nghệ của phương pháp EOR, . | Journal of Mining and Earth Sciences Vol. 62 Issue 3a 2021 17 - 29 17 Study and apply the advanced analysis algorithm to screen the optimal enhanced oil recovery solution for oil and gas fields in Viet Nam Long Hoang 1 Thang Viet Trinh 2 Truong Hung Trieu 3 Quy Minh Nguyen 1 Ngoc Quy Pham 1 Hien Huy Doan 1 Linh Hoang 1 1 Vietnam Petroleum Institute Vietnam 2 Vietnam Oil and Gas Group Vietnam 3 Faculty of Oil and Gas Hanoi University of Mining and Geology Vietnam ARTICLE INFO ABSTRACT Article history Applying the methods of enhanced oil recovery EOR for oil and gas fields Received 18th Mar. 2021 has always many risks of economic and technology because EOR projects Accepted 29th June 2021 are influenced by many characteristic factors of the reservoir such as Available online 10th July 2021 structure of reservoir reservoir formation geological properties Keywords parameters of reservoir engineering production technology to EOR EOR analysis algorithm application. Some EOR methods have been successfully applied in the EOR Clustering world but when these methods conduct in specific reservoir with different geological characteristics tight production conditions have resulted in EOR screening criteria failures and ineffective economic even caused dreadful aftermath to be EOR screening methodology. handled in operations. Researches evaluations and EOR applications in Vietnam are limited and only carried out on a laboratory scale. Therefore the ability to be applied the EOR modern technology with a large scale or full field still faces many difficulties and the feasibility of projects is not high enough. The authors have been analysed all EOR projects successfully that applied many oil and gas fields in the world and then building EOR database. Based on EOR database a study has been conducted on statistical analysis to build EOR screening criteria for reservoir parameters from past to now. The study also combined in-depth analysis algorithms such as Fuzzy K - mean PCA .
