| 摘 要： | 东胜气田主要目的层盒2段为辫状河沉积,局部多期河道相互叠置、交错,横向砂体变化快;面积大,井控程度较低,依靠一种方法难以准确的分析沉积砂体的分布规律。利用岩心、测井、储层预测等资料,结合地质认识,分析沉积相特征;通过对地震反射强度属性特征分析,进行宏观控制,明确地震相特征及砂体分布,参考现代辫状河沉积模式和已钻井情况,最终确定沉积相的展布特征,并利用研究成果,进行井位部署。

| Abstract: | He 2 member is the main target zone of Dongsheng gas field and it belongs to braided river sedimentary environment,with local multiphase rivers mutually superposed and crisscrossed,quickly changed horizontal sand body,large area and lower degree of well control.Therefore,it is difficult to accurately analyze sedimentary sand body distribution regularity by relying on single method.With use of the data of core,logging,reservoir prediction,etc,combined with the geological understanding,the characteristics of sedimentary facies have been analyzed.Through the analysis of the characteristics of seismic reflection strength properties,with macro control,the characteristics of seismic facies and sand body distribution have been made clear.By referring to the contemporary braided river sedimentary model and the drilled well drilling,the distribution characteristics of the sedimentary facies have been ultimately determined.And therefore,the well site deployment has been carried out by use of this research results. |
