Dataset of Boreholes Drilled in the Coalfield of Wucaiwan Area in Eastern Margin of Junggar Basin, Xinjiang

Junggar Basin in Xinjiang is an important home to reservoirs of energy and mineral resources such as oil, gas, and coal in China. In this paper, a dataset of 20 boreholes drilled in the coalfield of Wucaiwan area that lies in the eastern margin of Junggar Basin (also referred to as the Dataset) was established based on secondary development and exploitation of existing borehole materials. In other words, the Dataset was established by extracting important information from existing materials of the boreholes such as coordinates and elevation of boreholes, thickness and color of strata discovered, and data from interpretation of logging curves. It consists of Excel database files of 20 boreholes. Each database file is comprised of 10 worksheets, namely Basic information of boreholes, Lithological beds based on logging interpretation, Beds based on geological record histogram, Beds based on comprehensive histogram, Lithological beds of boreholes, Names and codes of strata, Colors of beds, Configuration oflogging curves, Data from logging curves, and Data dictionary. The data in the Dataset can be read using software developed by Xi'an Shiwen Software Co., Ltd. (also referred to as Shiwen software) to plot 3D stereograms of stratigraphic sedimentary. This will help achieve a more intuitive understanding of the spatial distribution and 3D geological structures of sandstone bodies in Wucaiwan area and thus is significant for the research of the sedimentary environment in this area.

新疆准噶尔盆地是中国重要的石油、天然气、煤炭等能源与矿产资源储集区。本文基于准噶尔盆地东缘五彩湾煤田的现有钻孔资料开展二次开发与利用，构建了包含20口钻井的数据集（以下简称本数据集）。换言之，本数据集通过提取现有钻孔资料中的核心信息构建而成，涵盖钻孔坐标与高程、揭露地层的厚度与颜色，以及测井曲线解释数据等内容。该数据集由20个Excel数据库文件构成，每个文件包含10个工作表，分别为：钻孔基本信息、测井解释岩性层、地质录井柱状图层、综合柱状图层、钻孔岩性层、地层名称与编码、岩层颜色、测井曲线配置、测井曲线数据以及数据字典。本数据集可通过西安石文软件有限公司（以下简称石文软件）开发的专用软件读取，用于绘制地层沉积三维立体图，从而更直观地认知五彩湾地区砂体的空间分布与三维地质构造，对该区域沉积环境研究具有重要意义。
