尚家区块扶杨油层断层较发育,油藏类型复杂,加之近年来探井少,给开发井油水层的识别带来一定的困难。针对这一情况,在应用岩心、岩屑、井壁取心这些传统录井方法的基础上,结合岩石热解分析、气相色谱、显微荧光图像分析等地化录井分析技术,在油水层识别方面建立了S_1与S_1/S_2和R_1与S_1关系图板,形成了储集层流体性质的地化综合评价方法,使该区块的解释符合率提高了20%,为试油方案的确定起到一定的指导作用,同时也对老井的重新认识提供了依据。
The fault zone of Fuyang reservoir in Shangji block is relatively developed with complex reservoir types, and less exploration wells in recent years, which brings difficulties to the identification of oil and water reservoirs in development wells. In view of this situation, based on the traditional logging methods such as core, cuttings and sidewall coring, combined with logging analysis technology such as rock pyrolysis analysis, gas chromatography and micro-fluorescence image analysis, In the aspect of recognition, the S_1 and S_1 / S_2 and R_1 and S_1 charts were established to form a comprehensive geochemical evaluation method of reservoir fluid properties, which improved the interpretation consistency rate of the block by 20% Play a guiding role, but also provide a basis for the re-understanding of the old well.
