摘要

松辽盆地梨树断陷金山地区沙河子组、营城组气藏为构造背景下的岩性气藏,地层以砂、泥岩沉积为主,岩性相对单一。为了明确储层特征及分布规律,选用"相面法"对沙河子组、营城组地层进行地震相的分析,共识别出5种主要地震相类型。结合钻井取心岩相、沉积相识别及测井电性特征,利用各主要地震相类型与各沉积相类型相关关系,配合地震反射特征识别,有效地预测了无井区储层的沉积特征及其展布。
The Shahezi and Yingcheng formation gas reservoirs are lithologic hydrocarbon reservoirs in Jinshan region of Lishu fault depression,Songliao basin.The main sedimentary strata in this area were sand and mudstone;and lithology was relatively simple.In order to assess the reservoir characteristics and distribution,metoposcopic method was used to analyse the seismic facies.5 main seismic facies types were identified in the Shahezi and Yingchen formation.Combined with the core facies,sedimentary facies recognition and logging electrical characteristics,the result showed that there was remarkable correlation between the main seismic facies and sedimentary facies types.It was therefore concluded that seismic reflection could effectively predict the sedimentary characteristics and distribution of reservoir in non- well areas.
