胜北洼陷低幅度油藏测井评价方法研究

Study on Logging Evaluation Method of the Low Amplitude Reservoirs in Shengbei Sag

摘要: 胜北洼陷低幅度构造油藏受孔隙结构和油藏高度影响，油气选择性成藏特征明显，储层定量评价较困难。研究表明，储层特征与束缚孔隙度有一定相关性，利用束缚孔隙度建立了储层品质和饱和度评价新方法，较好地解决了低幅度构造油藏储层评价的难题，在胜北洼陷应用效果较好。

Abstract: The low amplitude structural reservoirs in Shengbei Sag were affected by pore structure and re-servoir height; the oil and gas had obvious selective accumulation characteristics; and the quan-titative evaluation of reservoir was more difficult. Study indicates that there is a certain correla-tion between reservoir quality and bound porosity. A new method for evaluating the reservoir quality and saturation is established by using the bound pore, by which the problem of low amplitude reservoir evaluation is well solved, and good application effect is obtained in Shengbei Sag.
