摘　　要：H新区勘探开发刚处于起步阶段,缺乏试油试采资料,产建实施具有不可控性,同时受到沉积和埋深的影响,储层可能受到生物降解作用而导致氧化破坏,储层油气水关系更为复杂,使用平常使用的地质录井方法不能准确辨认含油层系。特引进地化录井,通过定性和定量解释相结合,共同识别油水层,采用创建S1与Ps识别图版和引进地化亮点参数与S1相结合,发现S1与地化亮点识别图版效果更好,可精准识别含油层与水层。该技术为H区高精度判别含油层系和后续勘探开发奠定了技术基础。The exploration and development of new area H is just at the initial stage, lacking oil testing and production test data, and the production and construction implementation is uncontrollable. At the same time, affected by sedimentation and burial depth, the reservoir may be subject to oxidation damage due to biodegradation. The relationship between oil, gas and water in the reservoir is more complex, and the oil bearing series cannot be accurately identified using the commonly used geological logging methods. Geochemical logging is specially introduced to jointly identify oil-water layers by combining qualitative and quantitative interpretation. By combining the creation of S1 and Ps identification plates and the introduction of geochemical highlight parameters with S1, it is found that S1 and geochemical highlight identification plates have better effect and can accurately identify oil bearing layers and water layers. This technology has provided a strong technical basis for high-precision identification of oil-bearing series and subsequent exploration and development in block H.
