High-Temperature Mechanical Properties and Microstructure of High Belite Cement

Autor: Wu Zhiqiang, Xie Renjun, Yang Jin, Ni Xiucheng, Cheng Xiaowei

Publikováno v: Frontiers in Materials, Vol 9 (2022)

The use of the class G oil well cement for cementing in high-temperature deep-seated oil and gas wells declines its mechanical properties, which limit its application under high-temperature conditions. The high belite cement (HBC), a new class of ene

Research on the Mechanical Integrity of Low-Density Cement Mortar

Autor: Xie Renjun, Wu Zhiqiang, Cheng Xiaowei, Ni Xiucheng

Publikováno v: Frontiers in Materials, Vol 8 (2022)

Poor mechanical integrity of cement sheaths during the production of oil and gas wells may cause air channeling and water channeling issues in the wells, leading to severe safety problems, and adversely affecting the safety and efficiency of the oil

Fault Detection Method Based on Improved Faster R-CNN: Take ResNet-50 as an Example

Autor: Xie Renjun, Yuan Junliang, Wu Yi, Shu Mengcheng

Publikováno v: Geofluids, Vol 2022 (2022)

In view of the low accuracy of existing tomographic detection methods, in order to improve the accuracy of tomographic detection, a tomographic detection method based on residual network and Faster R-CNN is proposed. First, input the image into the R

Visualization method of seismic profile data based on adaptive mosaic

Autor: Xie Renjun, Yuan Junliang, Shu Mengcheng

Publikováno v: E3S Web of Conferences, Vol 352, p 01002 (2022)

Three-dimensional visualization of seismic profile data can better display seismic data information than traditional profile display, but there are mosaic errors in grid mosaic. In order to solve the problem of false mosaics, an adaptive mosaic metho
