克拉玛依油田三采试验区孔隙结构图版的建立与实用意义

ESTABLISHMENT OF A PORE STRUCTURE CHART AND ITSPRACTICAL SIGNIFICANCE IN TERTIARY RECOVERY PILOT AREA IN KARAMAYOILFIELD.

对克拉玛依油田二中区三采试验区克下组（ｋ）油藏的４１条实测毛细管压力曲线及渗透率、孔隙度分析数据，采用数据拟合方法，建立了在不同压力下的渗透率与孔隙度比值和汞饱和度的关系图版。毛细管压力的拟合曲线与实测的毛细管压力曲线有较好的一致世。

On the basis of 41 measured capillary pressure curves and analysis data ofpermeability and porosity in Lower Karamay forniation reservoir (T_2k) in tertiary recoverypilot area in middle District No. 2 in Karamay oilfield, this paper established the plot ofpermeability and porosity , rnercury saturation under different pressures by adopting data-matching method. Results show better agreement between predicted and measured capil-lary pressure curves.
