摘要
在砂泥岩地层中 ,影响油、气层识别的因素较多 ,尤其在复杂地质条件下准确识别油气层难度更大。为此 ,在掌握该区域测井、取心、试油等资料及充分认识区域性地质特征基础上 ,研制油气层测井解释标准应先选取可靠实用的测井曲线 ,经对测井资料校正后 ,绘制测井解释标准交会图 ,交会图中所反映的油气层解释标准精度与所使用资料的可靠性、代表性等密切相关。该方法在濮城油田已取得较好的应用效果 ,其研究方法可为其它油田开展油气层识别提供参考。
There are many factors to affect identification of oil and gas bearing layers in the sand-shale formation.Especially, it is more difficult to accurately identify the oil and gas bearing layers under the complex geologic conditions.Therefore,on the basis of knowing the local well logging data, coring data, oil test data and the regional geologic characteristics,we should first select practical logging datum for establishing oil and gas bearing layers interpretation standard.After the logging data correction, we can draw crossplots of the standard,in which accuracy of the standard is very closely correlated with reliability and representativity of the datum used.This method has been better used in the Pucheng Oilfield,and offers reference for other oilfields to identify oil and gas layers.
