| 中文摘要: |
| 针对致密油藏注水开发过程中动态裂缝的问题，提出了利用“方向性压敏”、“方向性相渗”的方法，利用室内物理模拟实验和油田矿场分析资料，建立方向性渗透率与注水压力的动态关系，实现不同方向上两相渗流规律的差异。结合致密油藏非线性渗流机理，建立动态裂缝影响下水驱开发的数值模型，研制全隐式快速解法。最终，新模型成功应用于长庆油田WY试验区块，为同类致密油藏开发提供借鉴。 |
| 英文摘要: |
| Aiming at the problem that caused by dynamic fractures in waterflooding development of tight oil reservoir, the methods of “directional pressure sensitivity” and “directional relative permeability” are put forward. According to laboratory experiments and field analysis data, the relationship between directional permeability and injection pressure is established, and the two-phase flow law in different directions is obtained. Differences. Combining with the non-linear flow mechanism of tight reservoir, the numerical model of water drive development under the influence of dynamic fracture is established, and a full implicit fast solution method is developed. Finally, this new model has been successfully applied in a certain block, which provides a reference for the development of similar tight reservoirs. |
