摘要/Abstract

摘要： 页岩气开发具有开发评价期短，评价井少（直井）的特点，直井密度低增加了储层精细描述和地质建模的技术难度。因此，建立研究区地层的岩性、物性和电性特征的定量识别标准，利用该标准对水平井水平段开展精细小层划分，并对实际钻遇地层厚度进行校正，将水平井水平段等效为多口平面分布的直井。在此基础上，以水平井段解析的各小层数据资料作为控制点，建立研究区精细构造模型。水平井多点地质信息解析，将水平段等效为多口评价井获取相关地质参数资料，可有效地弥补评价井资料少的不足。

Abstract: Shale gas exploration is characterized by short evaluation periods and few evaluation (vertical) wells. The low density of vertical wells for evaluation aggravates technical difficulties in detailed reservoir description and geological modeling. Therefore, this study established a quantitative identification standard for the lithological, physical, and electrical properties of the study area. This standard was used to carry out fine stratigraphic division of horizontal wells and sections, as well as performing stratum thickness corrections during actual drilling, to transform horizontal wells and sections into vertical wells with multiple laterally arranged openings. On this basis, data extracted from each layer of the horizontal section were used as control points to establish a detailed structural model of the study area. In the multiple-point geological information analysis, horizontal sections were considered multiple-opening evaluation wells to obtain relevant geological parameters, effectively compensating for the lack of data in evaluation wells.

Key words: high-quality shale, multiple-point geological information analysis, 3D geological modeling, Longmaxi Formation, Weiyuan Block
