摘要:: 针对盐穴储气库水溶建腔的优化问题，综合考虑水溶建腔过程涉及的诸多因素，结合非线性规划理论和水溶建腔的生产实际，建立了多井造腔工艺参数优化数学模型，计算得到最大造腔量和最小回罐量两种多井造腔工艺参数优化方案。研究表明：节约能耗不仅需要降低回罐量，而且需要保持卤水罐较低浓度；在淡水注入量一定的情况下，采用反循环的井越多，造腔量越大，配合高注入量可以显著增加造腔量，但卤水缓冲罐需维持较高浓度，能耗较大；较多地采用正循环，配合较低注入量，可以在满足淡水消耗量和卤水外输量要求下，减少回罐量，使卤水缓冲罐维持较低浓度，降低能耗。采用该模型，合理配置造腔井数并合理分配各井的循环模式、注入工质和注入量等参数，可以得到最优多井工艺参数配置方案，具有较好的指导意义。

Abstract:: In order to optimize the solution mining of salt-cavern gas storages, a mathematical model was established for optimizing the parameters of multi-well solution mining technology on the basis of non-linear programming theories and solution mining practices after comprehensive analysis was made on factors related with solution mining. Based on the calculation, two multi-well solution mining parameter optimization programs were prepared by considering the maximum cavern volume program and the minimum flowing back rate to the tank program. It is shown that, for purpose of energy conservation, the volume of brine flowing back to the tank shall be reduced, but also the concentration in the brine tank shall be kept at low level. When fresh water injection rate is given, the more the wells for reverse circulation are adopted, the larger the caverns are. And the volume of the caverns can be increased remarkably if the injection rate is high, but the energy consumption is higher because the concentration in the brine buffer tank is kept at high level. Generally, the program of normal circulation with low injection rate is used. Based on this program, the backflow is reduced on condition that fresh water consumption and brine delivery are satisfied. In this way, the concentration in the brine buffer tank is kept at lower level, so energy consumption drops. With this model, a practically optimal multi-well mining parameter arrangement program is developed by deploying the number of wells for solution mining rationally and arranging the circulation mode, injection working medium and injection rate for each well scientifically. The program plays an instructive role for field operation.
