乌南次凹隐蔽圈闭识别方法研究
|
摘要
在分析隐蔽圈闭形成区域地质背景、形成条件的基础上,应用地震属性提取、地震相控反演等先进的地球物理技术,从储集体宏观形态特征识别到储层单砂体精细刻画,预测位于不同构造部位、不同时期沉积的隐蔽圈闭。通过对已发现隐蔽圈闭成藏条件和成藏过程的剖析,形成乌南地区南一段隐蔽圈闭聚集油气成藏的模式。结合储层预测成果,提出该地区隐蔽圈闭勘探的目标方向,为乌尔逊凹陷下一步钻探提供理论依据。
Based on the analyses of the geological background and formation conditions of subtle traps,and with the application of the advanced geophysics techniques like seismic attribute extracting and seismic facies inversion,this paper,from the identifica tion of reservoir macro-morphology to the fine description of single sandbody,predicted the subtle traps in different tectonic loca tions and different sedimentary phase.By analyzing the accumulation conditions and process of the discovered subtle traps,the hy drocarbon accumulation mode in Nan-1 segment of South Wuerxun area was established.Combined with reservoir prediction re sults,this paper pointed out the exploration direction of the subtle traps in the area and provided theoretical references for the fu ture drilling and exploration in Wuerxun sag.
