Construction and Practice for Practical Teaching Base on Campus for Petroleum Engineering

Abstract

The necessity on construction for practical teaching base on campus for petroleum engineering is described from such three aspects as requirement of practical talents training, requirement of vocational skills training as well as requirement of subject construction and campus culture construction in this article, the construction mode of practical teaching base on campus for petroleum engineering is discussed and the advantage of establishing the practical teaching base on campus cooperated jointly by campus and enterprise is analyze. Finally, the efficiency produced by the practical teaching on campus is summarized with combination of the operation condition of practical teaching base on campus for petroleum engineering.

Class II Reservoir Polymer Injection Parameters Impact on the Oil Displacement Efficiency

“…As shown in Table 4, the enhanced recovery increases with the improvement of the injection rate when the injection rate is smaller than 0.3 pv/a, which is opposite when the injection rate is more than 0.3 pv/a. Therefore, to a certain limit, a higher injection rate can improve the recovery of polymer flooding [14,15]. However, when the injection rate is too high, the injection pressure would increase, and the large pore path and dominant flow channel is formed during the sandstone formation, which means the displacement fluid flow along the large pore path, can't be swept in the low permeability areas, thereby reducing the displacement efficiency.…”
