Abstract: In this paper, the author established a geo-mathematical model using log information according to the concept of oil/water phase permeability. It can give oil/water phase permeability either in the form of curves or numerical data which varies with type of rocks, their physical properties and oil contents Thus the oil and water production rate can be calculated qualitively or quantitatively, the watered-out zone can be classified according to their degree of flooding and distribution of remaining oil can be discribed. It is demonstrated that the oil/water phase permeabilities calculated by this method possessa higher degree of precision when applied to shuang-he oil Field. It will give a geological basis for the development of a heterogeneous reservoir and add new contents to the interpretation and application of well logging data.

摘要： 本文根据储层油水相渗透理论,利用测井资料,建立了储层油水相渗透率地质、数学模型.它可以准确地给出随储层岩性、物性、含油性变化相对应的油水相渗透率变化曲线和数值,从而可定量或定性地计算剩余油产能、产水率,划分水淹等级,描述剩余油分布.经在双河油田实际应用和验证,该方法计算的油水相渗透率数值达到较高精度,为非均质油田的开发提供了新的地质依据,给测井资料解释和应用增加了新内容.
