高度非均质复杂断块油田油层有效厚度的确定方法

针对高度非均质复杂断块油田地质特点，采用分层划块、去异存同的原则，综合应用岩心分析、生产测试、测井及关键井研究成果。利用含油产状法、测试法、泥浆侵入法、数理统计法、经验统计法和综合分析等方法，确定了枣南孔一、孔二段５套有效厚度划分标准，制定了适应油田特点的有效厚度夹层扣除原则及标准，对枣南１５０口井近万ｍ井段的有效厚度进行了详细的划分与标定

DETERMINATION OF EFFECTIVE THICKNESS OF OIL RESERVOIR IN OILFIELD WITH HIGH HETEROGENEOUS AND COMPLEX BLOCK

The determination and partition of effective thickness of the reservoir is a basisfor evaluating the accumulation energy and production capacity of oil reservoir,as well as forregulating the exploitation program of oil field. Depend on the core,production test andwell-logging data of key well,the standards for partition of effective thickness and deductionof inter layed bed in the oil reservoir with the high heterogeneous and complex block oilfieldsare determined by the use of oil-bearing occurence analysis,the calculation of capillarypressure curve, the estimation of relative permeability curve,the core analysis of internalcoring well method and the inversion method of well-logging interpretation. The partitionstandards were applied to analysis of Zaonan oilfield.The result is satisfactory.
