摘要
松辽盆地西部斜坡区萨尔图油层属于稠油,油藏类型复杂,造成储集层流体性质识别难,解释符合率较低。为提高解释评价水平,应用核磁共振录井技术获取储集层孔隙度、渗透率、原始含油饱和度、可动油饱和度、含水饱和度及残余油饱和度等参数,结合试油资料对比建立西部斜坡区储集层物性评价标准,应用含油性评价参数建立了松辽盆地西部斜坡区萨尔图油层的解释标准。含油饱和度-孔隙度解释图板及可动油/可动水-束缚油/束缚水解释图板应用于25口井、统计18层结果表明,核磁共振技术解释符合16层,解释符合率为88.9%,较原解释符合率提高了4.8%。该项新技术的应用对于地质录井快速评价有效储集层、指导现场钻进,为综合解释评价及测试提供可靠数据等方面均具有重要意义。
Saertu oil reservoir in west clinoform region of Songliao Basin belongs to heavy oil with complex types,which resulted in difficult identification of reservoir fluid properties and lower interpretation compliance rate.In order to improve the level of interpretation and evaluation,by using NMR logging technology to obtain reservoir porosity,permeability,initial oil saturation,movable oil saturation,water saturation,residual oil saturation and other parameters,combining with the oil testing data correlation,the evaluation criteria of reservoir physical property for west clinoform region were established.The interpretation criteria for Saertu oil reservoir of west clinoform region in Songliao Basin was set up by using oil-bearing evaluation parameters.The criteria were used to 18 layers of 25 wells,the statistical results showed that NMR interpretation was consistent with 16 layers,the interpretation rate was 88.9%,the consistent rate was increased by 4.8% against that of original interpretation.The application of this new technology is important for rapid geologging evaluation of the effective reservoirs,guiding field drilling and providing reliable data for comprehensive interpretation and evaluation and testing.
