However, the parabola formed by the jet efflux

was much nearer to the injection wells which was

related with the flow rate. The enhancement of

efflux velocity would increase the injection flow

rate, resulting in lower concentration of brine,

which can be adopted with the larger cavern vol-

ume in the late stage of the construction of cavity.

4 CONCLUSION

Both the superficial area of the initial cavity and

flow rate of injection of the double-well convection

salt cavern were larger than that of the single-well.

Furthermore, the oil level control of the double-

well cavity was more complex than the single-well.

There were a variety of options in controlling the

elevation of the level of the flow. It was shown by

the experiment that low oil le ...
