The reasons resulted in these variations lay in sharp variation in fluid salinity and fluid pressure of reservoir after long-period water injection.
造成这种变化的原因在于长期注水后储层中流体矿化度和流体压力的剧烈变化。
The influence of initial temperature of reservoir is fairly important, and the initial pressure of reservoir is little important.
油藏初始温度对火烧油层驱油效果影响较大,而油藏初始压力则影响较小。
The real entrance pressure of reservoir rocks is a key quantitative parameter calculated during the exploration and exploitation of oil and gas.
储集巖石的真实突破压力是油气勘探开发中一项定量计算的关键参数。
