The Production Dynamic Analysis of Tianwaitian Gas Field Gas Condensate Reinjection Gas Well

Titian gas field has about 100m³/d gas condensate that is require 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 has problem, the gas condensate will be unable to output. Which is bound to seriously affect gas field production. When in Tianwaitian CEP platform construction, considering the above-mentioned risks, and learning from the Pinghu oil gas field processing sea pipe accident experience, once encounter the accident then the operators should temporarily re-inject the gas condensate into gas well, re-injecting the gas condensate to gas well has yet no precedent. Reinjection may cause unpredictable risks. In order to ensure the long-term production safety of Tianwaitian gas field, to carried out the production dynamic analysis of the reinjection gas well, providing the basis for the selection of the reinjection well.
