甘谷驿油田唐157井区注水开发实践及效果分析

Practice and Effect Analysis of Water Flooding Development in Tang 157 Well Area of Ganguyi Oilfield

甘谷驿油田唐157井区油藏地质特征与储层特征研究表明井区长6油藏属于低渗透油藏,针对目前开发现状及目前存在的主要问题,通过已有井的动态资料研究单井产能、含水率变化及其油井产量的变化规律,对注采、井网系统、注水情况、水驱状况、动用状况及注水井的受效特征进行分析,综合评价了唐157井区的注水开发效果,为特低渗透油藏注水开发提供了可借鉴的经验。

Petroleum geological characteristics and reservoir characteristics in Tang 157 well area of Ganguyi oilfield were studied. The results show that Chang 6 reservoir in the well area belongs to low permeability reservoir. Based on the current development situation and existing problems, through analyzing single well production dynamic data of existing wells, changes of single well production and moisture content were studied as well as the change law of oil well production rate; The injection production, water injection well network system, water flooding status, producing situation and water injection effect characteristics were analyzed, comprehensive evaluation of water flooding development effect in Tang 157 well area was carried out, which could provide reference for waterflooding development of ultra-low permeability reservoirs.
