地化录井综合解释评价方法在尚家区块开发井的应用

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St与S1／S2和R1与S1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 application of comprehensive interpretation and evaluation method about geochemical logging in the development wells in Shangjia Block

As the faults of Fuyang Reservoir in Shangjia Block are well-developed with complex reservoir types and with less exploration wells in recent years,all these have brought certain difficulties to the distinction of the oil and water zones in the developing wells.In view of this problem,on the basis of traditional mud logging methods,such as core, cuttings,sidewall coring,etc.,the relationship charts for S_T with S_1/S_2 and R_t with S_T have been established for oil and water zones,therefore forming the geoc...
