萨北开发区西部断层区精细挖潜模式

Potential-tapping Patterns in the West Faulted Zone of North Sa'ertu Development Area

萨北开发区西部断层较为发育,共发育大小断层49条,占全区断层总数的71%。针对断层区存在注采关系不完善、地层压力低、动用程度低等问题,从构造特征认识和挖潜方式优化两个方面入手,形成了井震结合、综合验证、分类优化、配套挖潜的断层区整体挖潜模式,指导断层区注采系统调整、高效井设计,优化断层区注采参数和配套措施挖潜,取得了累计增油42.2×104t的好效果。

Faults were relatively developed in the west of North Sa'ertu Development Area,there were 49 faults in it,accounting for 71%of the total faults.In consideration of the problem of imperfect injection-production relationship,low formation pressure,low degree of production in the reservoir,based on the understanding of the structure features and optimization of potential tapping,the potential-tapping patterns of well-seismic integration,synthetic verification,classified optimization and matched potential tapping are used to guide the adjustment of injection-production system and high efficient well design in the faulted zone,to optimize injection-production parameters and matching measures of potential tapping in the faulted zone.The cumulative oil increment of 42.2×104t is achieved,and better development results are obtained.
