三维三相烃类二次运移模型
|
摘要
提出一个关于烃类二次运移的三维 (x_y_z)和三相 (油 气 水 )模型 ,适用于具有一定数量的井和地震剖面的勘探地区。解决了一维和二维模型不能历史地在三维空间中指出烃类的分布位置及其聚集量的问题。该三维三相模型主要基于连续性方程、流动势、达西定律和状态方程 ,并考虑了沉积压实、排烃量、流动势、浮力及毛细管力等主要驱动力 ,以及岩性、断层、裂缝及不整合对运移聚集的影响。其软件已实现了真三维模拟与真三维可视化 ,能历史地提供关于油、气、水的势、压力、饱和度、运移速率及流线的各种图件 ,以及烃类聚集量及其分布。讨论了有限差分、有限元及有限体积三种数值解法。这个三维三相模型在满加尔坳陷成功应用 ,其模拟结果与实际情况相符合 ,预测出的一些有利勘探目标已被最近的勘探结果所证实。
A 3?D and 3_phase (water_oil_gas) model of hydrocarbon secondary migrationis is presented.It is applicable to the exploration area where there exist quite a few wells drilled and seismic sections,and has some distinctive advantages to present the quantity and distribution of hydrocarbon accumulation in the 3?D time and space that 1?D and 2?D models could not reach.This model is mainly based on the principles of continuity equation,flow potential,Darcy's Law,equations of state,and also in view of the major driving forces of sedimentary compaction,hydrocarbon expulsion,fluid potential,buoyancy and capillary pressure, etc.and the effects of lithology,fault,fracture and unconformity on hydrocarbon migration and accumulation.The software of the model performs the true 3?D simulation and true 3?D visualization and can historically supply the various maps for the potentials,pressures,saturations,migration velocities and streamlines of water,oil and gas,as well as the quantity and distribution of hydrocarbon accumulation.Moreover, the three solutions of finite difference,finite element and finite volume are discussed.This model has been successfully applied to Manjar Depression.The simulation results are consistent with the real situation. Some favorable prospects have been proved by recent explorations.
