  Chinese oil network news November 8th to 10, Chinese petroleum logging company production logging Center successfully completed the Changqing Oilfield five plants yellow zone 3 national carbon capture and sequestration pilot test base in the first 29-103 wells gas injection profile logging task, marking the company's ultra low permeability reservoir has made a major breakthrough in technology services.

  It is reported that the pilot technology of carbon dioxide flooding is currently being carried out in some domestic oil field technical tests. Huang 3 area is the first carbon dioxide flooding and storage test area in Changqing Oilfield, and it is also the first super low permeability reservoir carbon dioxide flooding project in china. Compared with conventional water flooding technology, CO2 recovery technology can increase oil recovery by more than 7%~12%.

  Due to the use of liquid carbon dioxide in the project construction, the downhole temperature is low, the injection pressure is large, and the wellhead sealing requirements are high. In this regard, specifically responsible for the production organization of production center for the low temperature transformation of the downhole instruments and makes the instrument more adapt to the underground temperature environment, aiming at the characteristics of carbon dioxide injection supporting professional blowout prevention equipment, solve the construction problems of carbon dioxide corrosion, and overcome the wells, downhole flow feature reducing tool is unknown so difficult to achieve log low temperature and high pressure, made of qualified logging data.

  In the well logging task, the production center organized lean power, advanced deployment, compiled the construction plan, fully recognized the equipment, process and site risk, developed a detailed risk control measures to ensure the successful completion of construction work. Subsequently, the center explained the data of the well, and further qualitatively and quantitatively analyzed the injection amount and injection effect of carbon dioxide in each reservoir, which provided a reliable basis for the next test.
