地震相分析技术在伊通地堑储层沉积特征分析中的应用
|
摘要
伊通地堑L3井区主要产油层双阳组一段,砂体的厚度和分布横向变化快,具有典型的"源近流短"沉积特征,相邻井的砂体特征及其含油性各异,利用地震相分析技术对研究区的砂体沉积特征及其变化规律进行了精细刻画。分别利用传统的地震相参数分析技术和Stratimagic地震相分析技术对双阳组一段的地震相特征进行了分析,并将两种方法的分析结果进行互相补充和验证。在此基础上,对双阳组一段的地震相特征进行了划分。采用最能反映扇三角洲相和湖相的相标志(如泥岩颜色、岩性组合、沉积层理、沉积韵律和地层的测井曲线特征等)对主要地震相单元中的钻井资料进行了单井微相分析,并依此建立了双阳组一段地震相与沉积相的对应关系,将地震相转化沉积相。
The first member of Shuangyang formation is the main oil lay er in L3 well field,Yitong trough.The thickness and distribution of sand bodies have a quick lateral change,with the typical sedi- mentary characteristic of"close source and short distance".The characteristics of sand bodies and their oiliness are different be- tween neighbor wells.Therefore,seismic facies analysis technique was used to describe the sedimentary characteristics of sand bodies and their changing rules.The conventional seismic facies paramet- ric analysis technique and Stratimagic seismic facies analysis meth- od were separately used to analyze the seismic facies characteristics of the first member in Shuangyang formation.Then,the results of the two methods were mutually supplemented and verified.On the basis of this,the seismic facies of the first member in Shuangyang formation was classified.The facies marks which can best reflect fan deha and lake facies(such as color of mudstone,lithological combination,sedimentary beddings,sedimentary rhythms and characteristics of logging curves)were adopted to analyze the single well macrofacies from main seismic facies units,on this basis,the corresponding relationship between the seismic facies and sedimen- tary facies of the first member in Shuangyang formation was estab- lished and the seismic facies was converted into sedimentary facies.
