摘要
分析了储层天然裂缝和人工裂缝对新肇油田注水开发的影响;将“龟裂系数”和威利公式相结合,对油田不同区块裂缝的发育程度进行对比;根据注水压力的变化,研究了裂缝的开启过程及开启压力;通过线性注水试验,确定了比较适合裂缝发育方向单一油田的合理注采井网。
This paper analyzes the effect of natural fractures and artificial fractures on water flooding development in Xinzhao Oil Field.It combines 'crocodile coefficient' with Willey formula to correlate the development degree of the fractures in different blocks.According to the change of water injection pressure,it studies the opening process and opening pressure of fractures.Through linear water injection test,it determines reasonable well pattern which is suitable for oil field with single development direction of fracture.
