[Abstract]:Gas storage is an important way of natural gas storage and peak-shaving. There are four types of gas storage: depleted reservoirs, water-bearing reservoirs, salt caverns and abandoned mineral deposits. The reconstruction of depleted gas reservoirs into underground gas storage has the advantages of mature technology and low investment. In this paper, the related supporting technologies of gas storage reconstruction in depleted gas reservoirs are studied. The surface engineering supporting technology is taken as the main research content, and the gas injection technology is studied. This paper analyzes the equipment selection and capacity calculation of gas injection compressor and gathering pipeline as well as the optimization configuration method, and studies the economic benefit analysis method of gas storage construction and operation. Taking the engineering construction of Wen23 depleted condensate gas reservoir in Huabei Oilfield as an example, the surface matching technology, gas injection equipment selection and gathering and transporting pipeline of gas storage reservoir are determined. The economic benefits of construction and operation are calculated and analyzed by examples. In view of the situation of Wen 23 gas storage, this paper puts forward the hydrate prevention technology of methanol injection at the wellhead and heating of heating furnace, expandable refrigeration and external cold source refrigeration deshydrocarbon treatment process, and adopts the combination of electric power driven reciprocating compressor gas injection matching equipment. This scheme is more suitable for gas storage in plain areas such as Wen 23. The gas storage data used in this paper come from Wen23 gas storage, and some of the design data have been applied in the field, which has played a positive role in the smooth development of engineering construction.
