%X 孔隙度和岩石压缩系数等方面的研究在评价油藏弹性产能和动态地质储量方面有重要的应用价值.结合国家地震前兆 台网中心数据库8口井的数字化水位资料等,研究了承压井含水层介质在不排水状态下的孔隙度、固体骨架的体积压缩系数 和含水层内水的体积压缩系数.结果表明,孔隙度与固体骨架的体积压缩系数和含水层内水的体积压缩系数间存在幂函数关 系.在第1象限内,各井含水层介质固体骨架的体积压缩系数随着孔隙度的增大而增大;含水层内水的体积压缩系数随着孔隙 度的增大而减小.固体骨架和含水层内水的体积压缩系数间满足一元二次多项式关系,且含水层内水的体积压缩系数要比固 体骨架的体积压缩系数大,水更易压缩.另外,灰岩骨架的压缩系数相对小于砂岩骨架的压缩系数.<br>The study of porosity and rock compressibility etc has important application value in the evaluation of the elastic ca- pacity and dynamic geo1ogica1 reserves of the reservoir. Waterleve1 digita1 data of 8 we11s provided by the Nationa1 Earthquake Precursor Network Center are studied to exp1ore the relationship of porosity and volume compression coefficient between solid skeleton and water in artesian we11 aquifer medium under undrained condition. The results show that there exists a power func- tion relation between the porosity and the solid skeleton volume compression coefficient and water volume compression coeffi- cient in the aquifer. In the first quadrant, each we11 aquifer solid skeleton volume compression coe出cient increases with increas- ing porosity, whereas the volume compression coefficient of water decreases with the increase of porosity, with one of two quadratic polynomia1 relationships between the solid skeleton and water volume compression coe価cient in the aquifer. The vo1- ume compression coefficient of water in the aquifer islarger than that of the solid skeleton, and water is more easily com- pressed. In addition, the compression coefficient of limestone skeleton is relatively sma11er than that of sandstone
