摘要
红河油田川口地区长6致密油藏油气富集程度及产能差异较大,通过油藏主控因素分析、储层四性关系研究对储层重新评价;结合探明区块开发情况,分析认为沉积相带、砂体厚度、储层物性、风化壳淋滤作用是影响油气富集程度的重要因素;基于试油结果及测井资料的研究,确定了该地区长6油藏储层的岩性与含油性下限、物性下限、电性下限,并分层位建立了吻合率较高的二次解释模型,对储层的综合评价和该区开发部署具有指导作用。
Hydrocarbon enrichment and productivity of Chang-6tight oil reservoir varies greatly in Chuankou area,Honghe oilfield.Through main controlling factors analysis and four properties relationship research,the reservoir evaluation has been re-evaluated.In combination with development status,the main controlling factors are considered to be the followings,namely sedimentary facies,sand thickness,reservoir physical properties and the weathered crust leaching process.Based on the production testing results and logging data,the reservoir lithology and the separate lower limits of the oil-bearing property,the physical property and the electrical property have been determined.The secondary log interpretation models have been established and they are well matched with the situation of each horizon,which plays a guiding role in the comprehensive reservoir evaluation and development deployment in this area.
