高分辨率层序格架约束下的储层预测——以莫里青油田双阳组二段为例
|
摘要
伊通盆地莫里青断陷具多物源、多期次走滑断陷盆地的特征,其断裂复杂,物源期次、储层展布认识不足。文章应用高分辨率层序地层学原理,岩—电—震相结合,通过对莫里青油田双阳组二段层序主要界面的识别与对比,首次将研究区双阳组二段划分为4个四级层序(对应基准面中期旋回)和13个基准面短期旋回,建立了莫里青油田高分辨率层序格架。结合粒度分析、地震属性和地震相分析等方法进行沉积微相划分,进而利用相控随机建模的方法,拟合开发程度较高的A、B区块的储层展布特征,选取最优模型,实现对开发程度较低的C、D区块进行储层预测的目的。该方法成功在莫里青油田C区块南部双二段预测出6个有利含油储层,实现储层定性分析向半定量、定量化分析的转变。
With multiple sources and multiple stages for strike-slip,the Moliqing Fault Basin has a complicated fracture pattern,and the source stage and reserve distribution still remain discussing.By means of high-resolution sequence stratigraphy,combining lithologic,electric and seismic data together,the 2nd member of the Shuangyang Formation in the Moliqing Oilfield has been divided into 4 4th-grade sequences(equivalent to mid-term base-level cycles) and 13 short-term base-level cycles.A high-resolution sequence stratigraphy framework of the Moliqing Oilfield has been established.Grain size,seismic attribute and facies analyses have been applied to study sediment-ary micro-facies.Using facies-constrained stochastic modeling method,the reservoir distributing features of high-exploitation blocks A and B have been fitted and the optimal parameters and models have been selected.Then these parameters are applied to the reservoir prediction in blocks C and D which are in low exploitation degree.Six oil-bearing reservoirs in the 2nd member of the Shuangyang Formation in the south of block C have been predicted with this method.The change from qualitative analysis to semi-quantitative and quantitative analyses in reservoir research provides more reliable foundation for the exploration and development of lithologic reservoirs.
