摘　　要：随着油气勘探程度的不断深入,位于鄂尔多斯盆地西南部的彭阳区块延长组多口井发现特殊油气藏,通过综合应用多种录井技术(包括岩石热解、轻烃、核磁共振录井)识别彭阳区块特殊油气层,并建立解释标准与解释图板,解决了彭阳区块储层产油与产气不能准确评价难题。该方法在M 77井现场的实际应用取得了良好效果,使录井解释结果的准确性显著提高,为后期试油、试气层段的优选提供了准确依据。With the deepening of oil and gas exploration,many wells in Yanchang Formation in Pengyang Block located in the southwest of Ordos Basin,show special oil and gas layers.Through the comprehensive application of multiple mud logging technologies,including rock pyrolysis,light hydrocarbons and nuclear magnetic resonance logging,special oil and gas layers in Pengyang Block are identified,and interpretation standards and interpretation charts are established,which solved inaccurate evaluation of oil and gas production in Pengyang Block.Good results have achieved through actual application of M 77 well on site,and the accuracy of mud logging interpretation results of this method has been significantly improved,which provides an accurate basis for the optimization of later oil and gas test intervals.
