摘　　要：综合录井技术目前主要应用于地层划分、岩性判断、油气显示识别等方面,对储层物性评价的应用还处于起步阶段。通过对工程、气测及地质录井参数优选,总结出适用于东海西湖凹陷不同储集类型的砂岩储层孔隙度评价方法,可在钻井阶段快速计算出研究区花港组及平湖组砂岩储层孔隙度。实践表明,该评价方法可较为准确地实现储层孔隙度的随钻识别,为该区花港组与平湖组砂岩储层的随钻评价、后续作业决策提供了较为可靠的技术手段和参考依据。At present,comprehensive logging technology is mainly used in stratigraphic division,lithology judgment,distinguishing the shows of gas and oil,and so on.The application of reservoir physical property evaluation is still in its infancy.Through the optimization of engineering,gas logging and geological logging parameters,this paper summarizes the evaluation method of sandstone reservoir porosity suitable for different reservoir types in Xihu sag of East China Sea,which can quickly calculate the sandstone reservoir porosity of Huagang Formation and Pinghu Formation in the study area during drilling stage.Practice shows that the evaluation method can accurately identify reservoir porosity while drilling,and provides a reliable technical means and reference basis for the evaluation while drilling and subsequent operation decision of sandstone reservoirs of Huagang Formation and Pinghu Formation in this area.
