The casing deformation prevention technology based on the optimization of cement slurry is proposed to reduce the casing deformation of shale oil and gas wells during hydraulic fracturing. In this paper, the fracture ...
While computer modeling of annular displacement efficiency is widely applied in cementing engineering,modeling the displacement flow inside a casing or drill string for cementing operations has received less attention...
A high-level forum titled“Our Common Pride:Belt and Road Connectivity and Building a China-Laos Community with a Shared Future”was held at the National University of Laos on November 6,2023.The forum was co-hosted b...
For the past six decades,Uganda and China have enjoyed remarkable bilateral relations and Uganda being recently elected to chair G77+China mechanism is set to drive the relationship to even greater heights.That’s acc...

Determining reasonable fracturing stage spacing is the key to horizontal well fracturing.Different from traditional stage spacing optimization methods based on the principle of maximum stimulated reservoir volume,in t...
Diplomatic activities to boost confidence in global recovery After the conclusion of the First Session of the 14th National People’s Congress, China’s top legislature, and the First Session of the 14th National Comm...
The authors gratefully acknowledge the research project from“Research and test on optimization of calculation model for cementing engineering of high temperature and high pressure wells”(Grant No.CQCJ-2020-06).
The weight loss of cement slurry is the main cause of early annular air channeling and accurate experimental evaluation of the law of loss change is the key to achieve compression stability and prevent this undesired ...
Aiming at the problems of deep shale gas wells in Baima Block of Fuling Shale Gas Field, such as deep burial, complicated geological structure, frequent leakage, low penetration rate and low cementing quality rate, th...
