摘要
该文通过地化录井岩石热解和油气组分分析技术的有效结合,探讨了现场评价开发井油层水淹状况的方法剩余油饱和度法、横向与垂向对比法、地化剖面分析法和色谱组分谱图分析法。建立了河南油田不同水淹程度油层组分谱图图版和水驱油效率判别水淹程度标准。应用实践表明,地化录井应用效果较好,解释符合率达到了84.8%。
By effective combination of geochemical logging rock pyrolysis with oil gas composition analysis, the paper discussed the methods of well-site evaluation for the development well watered-out state, which were: remaining oil saturation, lateral and vertical correlation, geochemical profile analysis and chromatographic analysis. The author set up chromatograph charts of oil reservoir compositions for different watered-out degrees and watered-out degree discriminating standard by water drive oil ratio. The application showed that the geochemical logging result was better and the interpretation coincidence rate was 84.8%.
