某碎屑岩油藏石炭系开发效果评价

Evaluation on development effect of carboniferous system in clastic reservoir

针对某碎屑岩油藏石炭系Ⅰ油组生产效果差、开发水平低的问题,应用油藏工程研究方法,分断块对油藏天然能量大小、注水开发效果、地层压力保持水平及储量动用程度等开展深入分析与评价,研究认为目前注采系统不完善、水驱储量控制程度低是导致油藏地层压力水平低、开发效果差的主要原因。在今后工作中,应不断完善注采系统,通过加强注水逐步提高油藏稳产能力。

Petroleum engineering research method was used to resolve the problems of low output and poor development effect of one formation in Carboniferous clastic reservoir.The natural drives,water injection,underground pressure,and reserve producing in the reservoir were analyzed.It is found that imperfect system of injection and extraction and low reserve driven by water flooding contribute to low pressure of the reservoir and efficiency of recovery.The system of injection and extraction should be improved and water flooding should be upgraded to enhance the stable yield of the reservoir.
