目前,地震资料识别的地层厚度在15m左右,以薄互层为主的储层预测难度更大,本文以高分辨率三维地震采集资料为基础,针对南山湾油田A油层岩性目标为出发点进行资料处理后,应用地震属性提取与分析技术来定性的预测砂体平面分布范围,采取多参数特征反演技术来定量识别砂体的纵横向变化;结合现有开发井测井解释结果及动态反映对嫩W区块A油层进行滚动开发,取得了较好的效果,对动用类似油藏具有很好的借鉴作用。
At present, the thickness of the seismic data is about 15m. It is more difficult to predict the reservoirs with thin interbedded layers. Based on the high-resolution 3D seismic data, aiming at the lithologic target of reservoir A in Nanshanwan Oilfield, After data processing, seismic attribute extraction and analysis techniques are used to qualitatively predict the distribution range of sand body. Multi-parameter feature inversion technique is used to quantitatively identify the vertical and horizontal variation of sand body. Combined with the logging interpretation results and dynamic reflection of existing development wells The rolling development of the A reservoir in the tender W block has achieved good results and has good reference for using similar reservoirs.
