The immersion and electrochemical methods has been used to study the corrosion behavior of automotive steel Q255 in different content of snow melting salt (NaCl) solution. Immersion test show that, the snow melting salt solution is more corrosive than the natural snow solution. The corrosion rate of Q255 steel in the natural water water is smaller than that of the snow melting salt solution, with the corrosion rate of 0.021 07 mm/a after the immersion of 168 h.The corrosion rate increased with the increase of NaCl concentration of the snow solution.

Slug flow with varying degrees often occurs in gathering and transportation systems, which makes the flow in the pipelines fluctuate in a certain extent. The fluctuation caused by slug flow made the running of inlet devices in the gathering and transportation system and central treatment station unstable. The flow fluctuation at inlet must be considered when designing inlet devices (usually the primary separator) to inhibit shut down problems due to surpassed flow volume. Suitable design factors were usually considered to relieve the effect caused by flow fluctuation. However, the design factor usually could not solve the unstable problems completely, and dynamic simulation was very necessary.

It was found that the existing separator could guarantee the system operated stable though the inlet flow was fluctuated in a range. The design factor of the inlet primary separator equaled to 1.4 was caused by flow fluctuation.

There is usually difference between gas measuring permeability and liquid measuring permeability, particularly in low permeability reservoirs. Hq, Zb and Hs of the gas permeability and liquid permeability were measured by experiments in the Ordos Basin.

Therefore the result could be used as a demarcation to divide reservoir. The gap of gas permeability and oil permeability had a great relation to the clay mineral, wettability and surface area to the volume ratio.
