Steam drive pilot test in Block Qi40 has achieved ideal development result, but the sweep efficiency is low and stable production period is short because of reservoir heterogeneity.
Lastly, sweep experiment and drive experiment were made.
最后，进行了扫频实验和驱抖实验。

At normal temperatures, the oil driving efficiency and the sweep efficiency of water driving are low, and the crude viscosity increases after water drive.
