Condensate Oil Injection Research and Application in Pinghu Oil & Gas Field

In emergency, the condensate oil produced from gas well will be injected back to formation.For this question, condensate injection simulation was done and the result w as compared with practical operation data.Injection pressure, injection rate, injection time and condensate recovery were optimized.In addition, the effect of condensate injection on rock wettabiltiy was discussed.Field practice proved that computation results were accurate and reliable.
