The cumulative gas injection volume of the Liaohe gas storage group exceeded 20 billion cubic meters. The 12th round of gas injection is currently being carried out, injecting more than 10 million cubic meters of natural gas into the ground every day to continue to "prepare for" winter supply.
The Liaohe gas storage complex is a key project planned by the state and the largest gas storage complex in operation in Northeast China. In recent years, Liaohe Oilfield has vigorously promoted the construction of "10 billion cubic meters of gas storage" and promoted the expansion and production of gas storage. At present, three gas storages, Shuangtaizi, Lei 61 and Ma 19, have been put into operation.
At present, Liaohe Gas Storage Company uses high-precision seismic exploration technology in Shuangtaizi Gas Storage Double 6 Block to accurately locate high-quality reservoirs, increase gas storage space, and improve gas storage capacity. At the same time, it continues to improve supporting facilities, build multiple gas pipelines, and connect the gas storage with the three major gas transmission networks; actively explore new technologies, develop gas storage injection and production optimization technologies, and use big data and artificial intelligence technologies to predict natural gas demand and gas storage operation status, reduce operating costs, and ensure efficient and stable operation.
To ensure the smooth progress of this round of gas injection, the Liaohe gas storage group accurately assessed the geological conditions and expanded the effective storage capacity of the gas storage. Based on historical gas usage data and market demand forecasts, a detailed injection and production plan was formulated. With the help of information technology, the pressure, flow and other operating parameters of the gas storage were monitored in real time, and the injection and production strategy was scientifically adjusted to ensure that quick and effective measures could be taken in the face of various emergencies.
