【摘要】 储集岩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。该文提出的有效应力下的水平流动水银注入技术能获取地层情况下的真实突破压力及储层情况下的毛管压力特征值，与常规方法相比，其参数更接近地层实际。更多还原

【Abstract】 The real entrance pressure of reservoir rocks is a key quantitative parameter calculated during the exploration and exploitation of oil and gas. This paper presents a technology of horizontal mercury injection under effective stress. This technology can obtain the real entrance pressure under the condition of strata and the characteristic value of the capillary-pressure of reservoir rocks. In contrast to conventional methods,the parameters obtained by the method are more close to those of strata.更多还原
