摘 要: | 通过研究四川盆地建南构造建111、建页HF-1、建页HF-2井页岩气层地质、录井和测井特征,建立页岩气储层综合解释标准,取得主要认识:东岳庙段页岩气储层厚在40m以上,岩性主要为深灰色泥页岩,脆性矿物含量≥65%;孔隙度3.0%~6.5%,渗透率2.1md~3.6md,含气饱和度55.0%~65.0%,有机碳含量为1.0%~1.4%,地层压力变化正常;东岳庙段页岩气层核心参数如页岩厚度、孔隙度、游离气含量,部分或同时分别突破60.0m、10.0%和2.0m3/t,页岩气显示层可评价为Ⅰ类气层,试气易获高产。

Abstract: | On the basis of the research on geological and logging characteristics of shale gas reservoir of wells of Jian 111, Jianye HF-1 and Jianye HF-2 in Jiannan structure of Sichuan basin, the standard for overall interpreting shale gas reservoir has been established and the main information has been got that the depth of shale gas reservoir in Dongyuemi- ao section exceeds 40m where dark grey mud shale takes up majority, brittle mineral content is greater than or equal to 65%, porosity, from 3. 0% to 6. 5%, permeability, from 2. 1mD to 3. 6mD, gas saturation, from 55. 0% to 65.0%, organic carbon content TOC, usually from 1. 0% to 1. 45% and formation pressure changes regularly; that the eore'pa- rameters such as shale depth, porosity and free gas content break partially or simultaneously through 60. 0m, 10. 0% and 1. 0m3/t respectively and that shale gas display layer is estimated as Type A where it is liable to achieve high capaci- ty in testing gas. |
