胜利油区东营凹陷低渗透浊积岩主要分布在湖盆水体较深的沙三、下亚段,由于物源多、变化大,砂体受到埋藏深、隐蔽性强、灰质泥岩较发育等不利因素影响,使得地震储层预测难度较大。通过浊积岩岩石物理分析,结合地震反射特征,提出了利用约束稀疏脉冲反演和MCMC统计反演进行井间储层预测的方法,在某些区块应用后获得了很好的工业油流,有效地推动了低渗透浊积岩油藏的开发。
The low-permeability turbidites in Dongying Sag, Shengli Oil Region, are mainly distributed in the deeper third and lower subbasins of the lake basin, which are unfavorable because of the rich source and large variation of sandstone bodies, deep buried sand bodies, strong concealment and development of gray mudstone Factors affect the prediction of seismic reservoirs more difficult. Based on the petrophysical analysis of turbidite and the characteristics of seismic reflection, a method of predicting reservoir between wells using constrained sparse pulse inversion and MCMC statistical inversion is proposed. After some blocks are applied, good industrial oil flow , Effectively promoted the development of low permeability turbidite reservoir.
