海上油田对注入水质要求严格、水源研究日趋重要。沙东南一渤中地区为渤海油田重要产区，注入水源充足与否直接决定着油田开发生产是否顺利。本次针对该地区，对主要水源目的层馆陶组进行了水资源量评价研究工作。馆陶组储层系统研究表明，馆陶组砂岩虽然分布广、但厚度变化大、物性非均质性强，具体油田馆陶组水源条件因此有所差异。采用容积法对沙东南一渤中地区馆陶组储层水资源量进行了计算，该区馆陶组水资源量为3366×10^8m^3，其中Ngl段水资源量为840×10^8m^3；Ng2段水资源量为483×10^8m^3；Ng3段水资源量为2043×10^8m^3。总体水资源量比较充沛，能够满足沙东南一渤中地区各油田长期开发对水资源的需要，但分布复杂，需要针对具体油田进行深入研究。

Most reservoirs of the Baiju oilfield are complex fault block pools with faults developed in the reservoir.The blocks are small and closed.the reservoir permeability is low , the pour-point and oil viscosity is high.which makes it difficult to displace oil by water looding. Soon after injectors are brought into production,the injection pressure is increased rapidly. Meanwhile,the injectivity decreases dramatically,which leads to little benefit to corresponding oil wells. The single well water injection stimulation development model on one hand to make full use of the sandstone of hydrophilicity, according to close water medium self-priming exhibit realize water flooding mechanism, on the one hand, the complement of formation energy, restore formation pressure, realize the artificial supplement energy. Not only extend the water flooding affected radius, improve oil displacement efficiency, also improve energy supplement no fault block recovery, this technology in high pour-point oil reservoir of prac- tical application get better effect.
