Research and Application of Well Control Technology for Deepwater Relief Wells in the South China Sea Oilfield
The deep water oil and gas resources in the South China Sea are an important strategic replacement area for ensuring national energy security.Deep water well control with a depth of several kilometers is even more difficult.In the process of drilling and completing oil and gas wells,once a serious blowout or a vicious accident of blowout out of control occurs.In response to such catastrophic well control accidents,the proposal of Relief wells is an effective method of well killing,and while suppressing the blowout,Relief wells can also replace accident wells to continue drilling or oil and gas production,with the characteristic of"win-win".
