【摘要】：为保证储气库造腔正常进行,需持续对造腔过程中的各项生产动态数据进行监控分析,及时发现问题并采取相应措施。对造腔过程中监测到的压力排量、排卤浓度、形态体积等生产动态数据实际值与计算的理论值进行对比,通过分析两者的差异性与油垫深度、两管距、不溶物蓬松系数等造腔参数之间的关系,形成了一套根据生产动态数据判断造腔参数是否异常的方法。如果造腔过程中造腔内管脱落,会出现油垫压力实际值大于理论值,排卤浓度实际值小于理论值的现象;若油垫上升,则油垫压力实际值小于理论值,排卤浓度实际值大于理论值。结合声呐测腔数据,用生产实例对该方法进行了验证,对分析造腔过程是否偏离设计方案具有重要的指导意义。
[Abstract]:In order to ensure the normal development of gas storage chamber, it is necessary to continuously monitor and analyze the production dynamic data in the process of cavity building, find the problems in time and take corresponding measures. The actual values of production dynamic data, such as pressure displacement, halogen concentration, shape and volume, which were monitored during cavity making, were compared with the calculated theoretical values. By analyzing the differences between them, the oil cushion depth and the distance between two pipes were analyzed. Based on the relationship between the cavities parameters such as the fluffy coefficient of insoluble matter, a set of methods for judging whether the parameters of cavities are abnormal or not are formed according to the production dynamic data. If the tube falls off during cavity making, the actual value of oil cushion pressure is larger than the theoretical value, the actual value of halide concentration is less than the theoretical value, and if the oil pad rises, the actual value of oil cushion pressure is less than the theoretical value. The actual value of the discharged halogen concentration is larger than the theoretical value. Combined with sonar cavity measurement data, the method is verified with a production example, which has important guiding significance for analyzing whether the cavity making process deviates from the design scheme.
