摘要
依据油气成藏动力学理论,在流体运移动力系统划分的基础上,对地层油气藏成藏动力进行了探讨。通过对济阳坳陷地层油气藏各区块成藏动力进行计算,发现不少区块的净浮力的分力小于毛细管力,这与实际是矛盾的。通过分析原因,确定了含油高度的主控因素。最后,用spss软件对含油高度主控因素进行多元回归,得到计算含油高度的拟合公式,实现了对地层油藏钻前定量预测。
In this paper,Based on fluid migration dynamic system division,reservoir-forming dynamics and oil-bearing prediction of the stratigraphic hydrocarbon reservoir in Jiyang Depression are researched.By calculation of reservoir-forming dynamics of blocks in Jiyang Depression,component of buoyancy force in many blocks is less than capillary force.By analysis,main controlling factors of oil height are determined.By Multiple regression of main controlling factors of oil height,oil height prediction formula is gained,and quantitative prediction of the stratigraphic hydrocarbon reservoir in Jiyang Depression is realized before drilling.
