摘要
含油气检测是利用油气层不同于水层或干层的地球物理响应,直接识别储集层流体类型的研究。含油气检测工作大体可以分为两步来进行,那就是识别和追踪。具体方法有:地震属性-地质分析、信息分解、多属性优选、多属性综合预测。在胜北3D地震覆盖区,有胜深3、胜北3等探井10口,其中获工业油气层两层,J3k油气层和K1l油层。J2q油气层为该区重要的油气层,邻区有多口井获得了高产油。运用多属性综合等方法对它们进行了含油气检测,确定了它们各自的油气分布范围。在油气检测的有利区新钻的Shb16井在J3k获得油气层,证实了检测结果的准确性。
The detection of hydrocarbon potentials is to recognize the fluid type of reservoir directly by using the different seismic response of oil & gas strata from water layers or dry layers. Detection work can be carried out in two steps: recognition and tracking. Concrete techniques for hydrocarbon detection include seismic attributes and geological analysis, data decomposition, multiple attributes optimization and prediction by integrating various seismic attributes. There are 10 wells, including Shsh3, Shb3 and so on, within Shengbei area, thereinto two oil & gas layers, J3k and K1l, have been found. J2q is another important hydrocarbon stratum in the area and high yield layers have been found at the stratum in many wells in nearby areas. Hydrocarbon potential detection technique by integrating multiple attributes has been used at these two strata to determine their oil-gas distribution respectively. Oil & gas reservoirs have been found in the newly drilled well Shbl6 in detected favorable region, proving the accuracy of the detection result.
