针对长芦油田油层连通状况低,注水开发效果差,笔者以扇三角洲沉积模式为指导,应用岩心、测井以及动态资料,在沉积微相研究的基础上,开展了单期复合砂体和单一砂体级次的构型解剖;分析了合理的注水井距,验证了注采关系之间的矛盾。研究成果与生产动态验证一致,为后期以注水为目的的开发调整部署提供了依据。 Aiming at the low reservoir connectivity in Changlu Oilfield and the poor water injection development effect, the author, based on the fan delta depositional model, applied core, well logging and dynamic data to study the sedimentary microfacies, Sand body-level configuration anatomy; analysis of a reasonable injection well spacing, verify the contradiction between injection and production relations. The research results are in line with the production dynamic verification, which provides the basis for the development and adjustment of waterflooding in the later period.
