Study on the Development Strategy of Thin Interbed Fault Block Reservoir in Offshore Oilfield:A Case Study of A Oilfield in Weizhou

HUANG Dongmei;ZENG Xiaoming;CHEN Xiaowu;YANG Yong;Zhanjiang Branch of CNOOC Ltd.;  
Reservoirs in the 3rd member of Liushagang Formation of Weizhou A Oilfield,Weixinan sag,Beibu Gulf basin are characterized by thin interbed,small fault block area and poor economic feasibility,though there are large scale of oil and gas resources.The well pattern and well density were determined by analogy method,formula of production capacity,modified Shercachev formula method and the water flooding control degree method,according to the present situation of reservoir development.The well spacing was confirmed via a comprehensive study of reservoir distribution,reservoir physical properties and developed fault block oil field analogy.The development mode was decided by comprehensive analysis and comparison of natural energy development,water injection and gas injection and puff to determine the way energy is added.
