Banqiao Storage Group Multi-cycle Operation

Abstract

This chapter introduces the operation efficiency and operation effect of six gas storage facilities in the Dagang area. Among them, the Dazhangtuo facility has reached the designed working gas volume after 18 cycles of operation. Its working gas ratio is high, and the operation effect is good. The Ban 876 gas storage facility has not reached the designed working gas volume, and its operating efficiency is low. After four new infill wells were drilled, the capacity expansion effect gradually became more prominent in the subsequent cycle. The main operation technical indicators increase, and the operation efficiency is improved. The Central North Banqiao gas storage facility has accelerated the capacity reaching and expansion project goal. Six new injection and production wells were drilled, and the capacity expansion effect was gradually observed in subsequent cycles. Apart from the Dazhangtuo gas storage facility, the capacities of the other five gas storage facilities have reached or even exceeded their design indexes. However, the working gas volume is far from the design program, with low working gas ratios. The current expansion rate is reduced, the major storage technical indicators increase slowly, and there is little room for improvement.
