复杂岩性地层物性参数实验评价

EXPERIMENT EVALUATION ON PHYSICAL PARAMETERS FOR COMPLICATED LITHOLOGY RESERVOIR

通过实验的方法研究了大庆外围的变质岩在不同围压下的物性参数,通过对多口油井大量岩芯样本的分析,得出了岩石渗透率、孔隙度以及孔隙体积压缩系数随压力变化而变化的规律,为复杂岩性油气藏的开发、压注增产工艺的实施提供了理论依据。

The physical parameters of the metamorphics of Daqing peripheral reservoir are studied by testing under different confining pressures.The variation rules of permeability,porosity and volumetric compressibility with pressure are obtained.The study result will provide theoretical basis for the development of complicated lithology reservoirs,as well as their fracturing and water injecting.
