摘要
为了提高产量，根据现有的技术和设备设计出切实可行的最优钻关方案，通过选择有代表性的钻关区块，跟踪录取钻关全过程的动态资料，分析研究钻关过程中地层压力、流压、产油量、产液量、含水率、采液指数及注采比的变化规律，预测钻关对开发指标的影响。在分析所建立的物理模型的基础上，选一种符合实际的物理模型并利用数值模拟进行机理研究，建立的理论计算曲线应用于实际工作后取得了较好的效果。
In order to enhance oil production in this case, according to the practically optimized program designed by using current techniques and equipments, by choosing typical shutting-in blocks and follow-up obtaining of dynamic data in all the process, the changed laws on the formation pressure, flow pressure, oil and liquid productions, water cut, liquid production index and injection-production ratio are analyzed and studied, and moreover the influences of the shutting-in on development indexes are predicted. On the basis of analysis of the established physical model, the practically physical model is chosen, and then with the help of numerical stimulation, the mechanism is researched, much better effects are accomplished in the actual operation by establishing the theoretically calculated curves.
