卫星-升平地区北部登娄库组三维地质建模研究
|
摘要
卫星-升平地区北部登娄库组是勘探开发深层天然气重点区域,而储层评价问题是制约深层天然气勘探开发的主要问题之一。针对松辽盆地北部卫星-升平地区深层登娄库组井资料少,研究程度低的特点,精确预测储层比较困难。因此,需要进行精细的油藏描述,建立精细的三维地质模型。综合地震、测井和地质的研究成果建立地层格架,结合相控建模,利用序贯指示随机模拟建模方法进行油气藏的属性建模,所建地质模型反映了地下地质体三维空间分布特征,为拓展油田登娄库组勘探开发和挖掘潜力,寻找有利储层发育带和天然气分布区规律提供有力依据。
The Denglouku Formation in northern Weixing-Shengping Area is the key area of deep natural gas exploration and exploitation,while reservoir evaluation is one of the key problems which restricts deep natural gas exploration and exploitation.Because there is less well logging data about the Denglouku Formation in Weixing-Shengping Area of the northern Songliao basin,and the insufficient research about this area,it is difficult to predict reservoir precisely.Therefore,the fine reservoir description and the establishment of the elaborate 3D geological models are needed.Stratigraphic framework is established by integrating seismic,logging and geological research results,and the reservoir attribute model is established by use of sequential indication simulation stochastic modeling method combined with facies-controlled modeling.The built geological model reflectes the three dimensional spatial distribution characteristic of the underground geologicals,which provides strong evidence for the expansion of the exploration and exploitation of Denglouku Formation,the development potential of the oil field,as well as the search for favorable reservoir and the distribution pattern of natural gas.
