A PREDICTION ON THE FAVOURABLE OIL—BEARING PLAYS IN THE FUYU RESERVOIR OF THE SONGLIAO BASIN BY THE APPLICATION OF CHARACTERISTIC ANALYSIS
-
摘要: 本文应用特征分析方法,以松江盆地新民、扶余及新立油田作为模型区,选取七个有意义的地质变量,采用多种求权系数及剔除变量数的办法,分别建立了扶余油层最优模型公式。根据权系数大小得知,油气聚集受距生油凹陷中心距离、青一段排烃能力、所在沉积相区的影响较大,其它因素影响次之。用最优模型公式结合物性分析认为:扶余油层应先勘探龙虎泡-大安阶地,南部为华字井阶地中南部、扶-新凸起西部斜坡带。Abstract: Applying characteristic analysis,the authors of this paper set up an optimum mod- elling formula of the Fuyu oil reservoir from the study areas of the Xinmin and Fuyu Oil-fields in the Songliao Basin。In this modelling formula seven significant geological vari- ables are selected with various weighed coefficients.According to the value of weighedcoefficients,it is revealed that oil/gas accumulation should be predominantly controlledby the distance from oil-generating center of depression to the accumulation,hydrocar-bon expulsion of the lst section of the Qingshankou Gr.(Fr.)and sedimentary facies inplace rather than other factors.Combined with physical analysis,it is believed that thebest oil/gas prospects in the Fuyu oil reservoirto be located in the Longhupao-Daan ter-race,of which the south area is in the central south of the Huazijing terrace and thewestern clinoform zone of Fu-Xin uplift.
