稠,稀油并存区块地震解释精度研究

方法从地震资料品质分析及改善，合成地震记录制作及标定，构造形态及断裂特征分析入手，对兴—冷接壤带的三维地震资料进行精细解释。目的提高地震解释精度，寻找稠、稀油并存区块的有利圈闭。结果通过应用新的精细解释方法，解释精度大大提高，在兴—冷接壤带新发现的田１５、田２、冷２三个断块圈闭为该区油气聚集的最有利圈闭。结论提高地震资料品质和层位标定的准确性是提高地震解释精度的基础；构造分析的合理性是提高地震解释精度的关键；而提高地震解释精度是寻找稠、稀油并存区块有利圈闭和后备储量的必要途径

Seismic interpretation accuracy study for blocks with combined crude viscosity.

Method\ 3D seismic data from Xing-Leng transitional area is finely interpreted by analyzing and improving its quality, developing and marking synthetic seismograph, analyzing structures and rift characteristics. Purpose\ To improve accuracy of seismic data interpretation such that to find favorable traps in blocks with combined crude viscosity. Result\ Using this new finely interpretation method, interpretation accuracy improved and three favorable fault blocks found in Xing-Leng transitional area. Conclusion\ Quality improvement of seismic data and accurate stratigraphic division are critical for upgrading accuracy of seismic interpretation; furthermore, enhance interpretation accuracy is also essential in searching for blocks with combined crude viscosity and future reserves.
