InverMod反演技术在PH油气田的应用
|
摘要
PH油气田A油藏埋深较大,储层薄,利用常规波阻抗反演无法有效区分储层。为了能精细的描述储层,指导开发井的布井方向和井型设计,针对PH油气田A油藏的储层特点,利用Jason软件的InverMod反演技术进行储层预测。InverMod反演(测井属性反演)是一种在地质框架模型控制下,用地震资料作约束,以测井资料为主体的储层反演技术。该技术在PH油气田取得了较好的应用效果,反演结果表明A油藏储层非均质性强、横向变化快,成块状分布。储层预测结果与实钻生产井的钻探情况吻合较好,对井位优化、油藏挖潜都有一定的指导作用。
In PH oil/gas field,the oil reservoir A is thinner and deeper so that it can't be predicted by normal impedance inversion. In terms of this type of complex reservoir,InverMod is appllied to describe A reservoir distribution and design the development well grid.InverMod is a reservoir description and prediction method under the control of the geological model which is logging data oriented and constrained by seismic data.A reservoir was predicted by InverMod Inversion in PH oil/gas field.These predictions showed the strong heterogeneity and lateral variation of A reservoir.Predicted results is in good accordance with the drilled wells and have a guiding role in exploring potential and well location selection.
