鄂尔多斯盆地××井区上古生界气藏地质建模
|
摘要
××井区上古生界气藏属于典型的定容岩性致密气藏,目前处于投产初期,气井产能下降快,稳定产量较困难。因此,需要加强储层地质认识,寻找有利储层加密井网,确保气井稳产。通过对该区块目前的地质认识,充分利用现有资料,采用确定性建模和随机建模相结合的方法,建立构造模型、岩相模型、属性模型、有效储层模型。使模型与实际相符合,从而为下一步气藏数值模拟提供定量地质模型,也为下一步评价气藏及调整开发方案提供地质依据。
The upper Paleozoic gas reservoir in ×× well area belongs to a typical lithologic and tight gas reservoir with constant volume. At present, it is at the initial stage of production, and the productivity of gas wells declines rapidly, thus it is difficult to stabilize production. Therefore, it is necessary to strengthen the understanding of reservoir geology and search for an infill well pattern for favorable reservoirs to ensure stable production of gas wells. Based on the current geological understanding of the block and related existing data, this paper combines deterministic modeling with stochastic modeling to establish structural model, lithofacies model, attribute model and effective reservoir model with each model consistent with reality, thus providing quantitative geological model for the next numerical simulation of gas reservoirs, as well as geological basis for further evaluation of gas reservoirs and adjustment of development plans.
