A dataset of one high-angel well drilled and logged at Bohai Sea during FY2021

The dataset is acquired from an actual well is located in the southern part of Liaodong Bay in the Bohai oil field. The well is drilled with a 241.3 mm (9.5 inch) bit. During logging, the tool is slide against the borehole wall from the bottom to the top and sampled at 76 mm intervals. The sieve residue log shows that the logging section is dominated by sandy mudstone formations, and borehole fluid sampling shows that borehole fluid has a density of 1.18 g/cm3 with a salinity of 94 kppm. Neutron and density data are obtained according to the log depth interval. The dataset includes 4 files: XX19-1N.xtf is the original data from the well log that could be opened using a xtf viewer. XX19-1N-Data.txt is the data read from the original xtf file. detection.py is the data processing code and XX19-1N. las is the neutron porosity data that are processed using detection.py.

本数据集取自渤海油田辽东湾南部的一口实际作业井。该井采用直径241.3 mm（9.5英寸）的钻头钻进。测井过程中，测井仪器由下至上贴靠井壁滑行，并以76 mm的间隔进行采样。筛余测井结果显示，该测井段以砂质泥岩地层为主；井眼流体采样分析表明，井眼流体密度为1.18 g/cm³，矿化度为94 kppm。依据测井深度区间获取了中子与密度测井数据。本数据集包含4个文件：XX19-1N.xtf为该井测井原始数据，可通过xtf查看器打开；XX19-1N-Data.txt为读取自原始xtf文件的数据；detection.py为数据处理代码；XX19-1N. las为经detection.py处理得到的中子孔隙度数据。
