油藏监测是提高边际油田的经济效益或延长老油区的开采期限的基本管理工具。以前曾有效的常规监测方法(包括井下测量和生产测量)模拟油田模型生产动态预测有一定的局限性。例如只能间接推断分支油流和未排出的油,且许多油井已经受到了早期的水窜和气窜。这些局限是由于所采集的数据稀疏和不完整,以及模拟了地层的简化模型所致。对油藏的较详细的3D特证描述和对整个油田的流体运动和压力的观测将产生较可靠的及在相对各种油藏管理策略而言能提供较精确预测的模型。在特殊情况下,采用该模型来检测开发方位和加密井,从而可优化油井的产量和最终储量。
Reservoir monitoring is the basic management tool to increase the economic benefits of a marginal oil field or extend the mining period of an old oil region. Previously valid routine monitoring methods (including downhole measurements and production measurements) have some limitations in modeling dynamic predictions of oilfield production. For example, only the branch flow and unplumbed oil can be inferred indirectly, and many oil wells have been subjected to early water channeling and gas channeling. These limitations are due to the sparse and incomplete data collected and the simplified model that simulates the formation. A more detailed 3D characterization of reservoirs and observation of fluid motion and pressure across the field will result in more reliable models that provide more accurate predictions relative to various reservoir management strategies. In exceptional cases, the model is used to test development orientation and infill wells to optimize well production and final reserves.
