塔里木盆地海相砂岩油藏水平井水淹规律及其模式
Water-out performance and pattern of horizontal wells for marine sandstone reservoirs in Tarim Basin, NW China
摘要
Abstract
Based on geological analysis,reservoir numerical simulation and production performance analysis,water-out performance and pattem of horizontal wells in Tarim marine sandstone reservoir were studied.Compared with continental sandstone reservoirs,the marine sandstone reservoirs in Tarim Basin were characterized by low oil viscosity,good reservoir continuity,and development of interbeds,which together with the large amount of horizontal wells,resulted in fast production rate and high recovery degree of the reservoirs.The main controlling factors of uneven water-out in horizontal wells were reservoir seepage barrier,injection-production well pattern,and dominant seepage channel.Thus 9 types in 4 categories of typical water-out pattern of horizontal wells in Tarim marine sandstone reservoirs were identified,and water-out management measures were proposed for them respectively according to their water-out mechanism and remaining oil distribution characteristics.Finally,the water-out pattern can be identified based on the inflection characteristics of derivative curve of water-oil ratio.This study of the water-out pattern can provide guidance for the adjustment policy of water injection in horizontal wells in marine sandstone reservoirs of Tarim Oilfield.关键词
