Feasibility Study of Tianwaitian Gas Field Gas Condensate Reinjection Gas Well

Tianwaitian gas field about 100m3/d gas condensate is required to be transported to Pinghu integrated platform, then transported to Daishan terminal through Pinghu-Daishan 16" oil sea tube. The platform is without storage means, Pinghu-daishan 16" oil sea tube has been in operation for 15 years. Once Pinghu-daishan 16" oil sea tube or Daishan terminal occur problems, gas condensate can not be outward transported. Which is bound to seriously affect gas field production. When in Tianwaitian CEP platform construction, Considering the above-mentioned risk, Learn experience from the Pinghu oil gas field processing sea pipe accident, Once had the accident temporarily re-inject the gas condensate into the gas well. Re-injecting gas condensate into gas well has not yet had a precedent, reinjection may cause unpredictable risks. In order to ensure the safety of long-term production of Tianwaitian gas field, it\´s necessary for Tianwaitian gas field implement gas condensate reinjection.
