摘要
非常规油气资源是当前大庆油田油气勘探开发中新的领域,其中页岩油的勘探开发正在逐步推进。为实现页岩油钻探中的快速解释评价,通过对井筒录井资料的分析,研究录井相关技术参数在页岩油井解释评价中的应用,初步建立了一套适用于页岩油评价的录井解释方法,即采用气测参数、岩性及岩心裂缝观察、地化热解参数、残余碳分析、元素分析等多种录井参数相结合,从岩性、物性(裂缝发育情况)、含油气性、烃源岩特性、脆性等层面对页岩油进行评价,并确定各参数的评价范围及脆性的计算方法。研究结果对松辽盆地古龙凹陷页岩油录井的解释评价具有一定的指导意义,也为该区页岩油的下一步开发提供了可靠依据。
Unconventional hydrocarbon resources are a new area in oil and gas exploration and development in Daqing Oilfield at present,in which shale oil exploration and development is advancing gradually.In order to realize the rapid interpretation and evaluation in shale oil drilling,through the analysis of wellbore mud logging data,the application of mud logging related technical parameters in shale oil well interpretation and evaluation is studied.A set of mud logging interpretation methods suitable for shale oil evaluation has been preliminarily established.That is,the shale oil is evaluated from the aspects of lithology,physical properties(fracture development),petroliferous properties,source rock properties and brittleness by using the combination of mud logging parameters such as gas logging parameters,lithology and core fracture observation,geochemical pyrolysis parameters,residual carbon analysis and element analysis,and the evaluation range of each parameter and brittleness calculation method are determined.The results of the study have certain guiding significance for the interpretation and evaluation of shale oil mud logging in Gulong sag,Songliao Basin,and also provide a reliable basis for the further development of shale oil in this area.
