沙埝油田阜三段测井储层评价研究

Study on logging reservoir evaluation in the third member of Funing formation,Shanian oilfield

通过对沙埝油田阜三段储层的四性关系分析,针对储层岩性复杂、物性差及非均质严重的特点,充分利用大量岩心分析资料和试油试采资料,并结合动态开发资料,建立适合该区的储层参数测井解释模型,分析检验和现场应用效果表明,所建立的模型是合理的,解释精度达到89%,有效提高了储层评价的质量。

Four reservoir characteristics(lithology,physical property, oil-bearing characteristics and electronic characteristics) and their correlations in the third member of the Funing formation,Shanian oilfield are analyzed.According to these characteristics,such as complex lithology,bad physical property and the aeolotropism,data of core analysis,well test,production test and development are used to establish the suitable well logging interpretation model of the reservoir parameters with the interpretation precision up to 98%at the area.Consequently,the quality of the reservoir evaluation is improved.
