摘要
录井技术与测井技术在解释评价油气层方面各具优势,又各有其局限性,因此开展录、测井技术综合解释评价研究,对于提高解释符合率具有重要意义。以吐哈盆地TYK地区稠油层为研究对象,结合实例和应用效果分析,探讨了利用地化录井结合测井技术解释评价油气水层的3种方法,分别为:①声波时差与热解烃总量解释评价法(ACPg法);②孔隙度与热解烃总量图板法(Pg法);③视地层水电阻率与地化亮点值图板法(RwaM法)。实际应用表明效果较好,其解释符合率达到90%以上。此项课题研究成果对于不同地质特征、不同油质、不同油气藏类型的解释评价方法的研究具有一定的指导意义。
Both mud logging and wireline logging technologies have their own superiorities and limitations on hydrocarbon reservoir interpretation and evaluation, so, developing the comprehensive interpretation and evaluation study of mud logging and wireline logging technologies has important significance for improving interpretation coincidence rate. Taking viscous crude layers of TYK area from Tuha Basin as an object of study and combining samples and applied results analysis, the paper introduced three methods which used geochemical logging and wireline logging technology to evaluate and interpret oil-gas-water layers, they are accoustic logging interval transit time & pyrolysis hydrocarbon quantum interpretation and evaluation method (AC-P_g method), porosity & pyrolysis hydrocarbon quantum chart method (-P_g method) and apparent formation water resistivity & geochemical bright spot value chart method(R_ wa-M method). The applied results of the above methods are good, their interpretation coincidence rate is over 90 per cent. The research results of this topic have a certain guiding significance for interpretation and evaluation method study to different geologic characteristics, different oil properties and different types of hydrocarbon reservoirs.
