摘要
作为喇萨杏油田稳产潜力的重要组成部分———表外储层 ,在注水开发中动用程度一直是人们普遍关心的问题。在油水井测试及密闭取心检查井资料统计分析基础上 ,研究了注水开发过程中表外储层的动用机制 ,取得了非实体连通是导致表外储层难采的地质因素 ;层间干扰是导致表外储层难采的动力因素 ,表外储层动用状况取决于基质与压裂裂缝间能量交换的能力 ;压力下降导致裂缝渗透性下降影响了表外储层的渗流等认识。进而认为在目前井网开采条件下表外储层能否起到预期的稳产接替作用是个值得进一步深入研究的问题。
Untabulated reservoir” is an important part of the stable production potential of Lamadian Saerto Xingshugang. Its producing degree in water flooding process is also an important problem. This paper analyzes the oil and water well testing and sealed coring examination well data statistics and studies the producing mechanism of “untabulated reservoir” in the water flooding development process. It concludes that, under the condition of well pattern production, if “untabulated reservoir” can continue the stable production is a problem worth a further study.
