随着煤层气产业的发展以及非常规油气勘探开发一体化的要求,当前煤层气的勘查评价工作逐渐由勘探选区向开发甜点选区推进。然而,受限于勘探开发阶段或资料占有程度,当前多数的选区评价体系对煤储层的可改性和煤层气的可采性考虑不足,在指导开发区井位优选或加密井方面效果不佳。基于沁水盆地柿庄北区块100余口煤层气参数井和开发井资料,分析区内3号煤层煤层气开发的资源条件、储层可改造性和煤层气可采性,采用层次分析和灰色定权聚类方法构建评价模型,评价了煤层气开发甜点区,为区内新井和加密井的部署提供依据。评价模型以煤层含气量、煤厚反映煤层气资源条件;综合考虑地应力环境和岩石力学性质,构建储层综合可改造性参数,评价储层可改造性;使用原始结构煤和碎裂煤占比、临储比和储层原始渗透率反映煤层气的可采性。每个参数采用word聚类方法分级,每个点位(每口井)计算出综合优度并排序,最终划分出煤层气开发甜点区。评价结果表明,研究区中部综合优度大于65的地区为进一步开展开发工作的甜点区。

低温氮吸附法是目前用于评估直径在0.35 nm~300 nm之间煤的孔隙结构广泛使用的实验方法,通过实验得到的数据可以表征出煤的孔隙结构特征。在低温氮吸附实验中,样品的粒径、脱气温度和脱气时间等因素对实验结果影响较大。为研究脱气时间对低温氮吸附实验结果的影响,进行了一系列其他条件不变,只改变脱气时间的实验,选择的脱气时间分别为2 h,3 h,4 h,5 h,6 h,9 h,12 h,24 h。选取三种中煤级煤岩样品为实验材料,分别为济宁三号井气煤、张北矿气煤以及临涣矿焦煤。研究不同脱气时间下中煤级煤样在低温氮吸附实验中孔隙结构的变化,以确定最佳的脱气时间。通过分析煤样的吸附曲线、吸附-脱附曲线“滞后环”、阶段孔容曲线、平均孔径等参数,发现煤样在脱气时间发生变化时,煤样孔隙结构也发生相应的变化。研究发现,煤样在脱气时间为2 h和3 h时吸附-脱附曲线的类型以H3为主,其孔隙结构简单。煤样测定的平均孔径在脱气时间为3 h达到最大值,平均孔径在脱气时间为5 h达到最小值。在脱气3 h时,水分对煤样孔隙结构的影响可以忽略不计,挥发分对煤样孔隙结构的影响较低,此时煤样的孔隙结构更佳。三种中煤级煤样最佳脱气时间为3 h。

Methane adsorption-induced coal swelling measured with an optical method

International Journal of Mining Science and Technology 2015年第6期25卷 949-953页

作者： Tang Shuheng Wan Yi Duan Lijiang Xia Zhaohui zhang songhang School of Energy Resources China University of Geosciences Asia-Pacific Department Petro China Research Institute of Petroleum Exploration & Development

In order to quantify the effect of matrix shrinkage on reservoir permeability during coalbed methane production, coal samples from Huozhou, Changzhi and Jincheng areas in Shanxi province （classified as high-volatile bituminous coal, low-volatile bituminous coal and anthracite, respectively） were collected, and adsorption-induced coal swelling in methane were determined by an optical method at 40 ℃ and pressure up to 12 MPa. All three coals showed similar behavior-that swelling increased as a function of pressure up to about 10 MPa but thereafter no further increase in swelling was observed. Swelling in the direction perpendicular to the bedding plane is greater than that parallel to the bedding plane, and the differences are about 7.77-8.33%. The maximum volumetric swelling ranges from 2.73% to 3.21 %-increasing with increasing coal rank. The swelling data can be described by a modified DR model. In addition, swelling increases with the amount of adsorption. However, the increase shows a relatively slower stage followed by a relatively faster stage instead of a linear increase. Based on the assumption that sorption-induced swelling/shrinkage of coal in methane is reversible, the permeability increases induced by coal shrinkage during methane desorption was analyzed, and the results indicate that the permeability change is larger for higher rank coal in the same unit of pressure depletion.

在“双碳”战略背景下,开展煤中封存CO_(2)和提高煤层气采收率(CO_(2)-ECBM)研究有重要现实意义,我国也已开展多方位的先导性试验和工程示范。已有的工程实验表明,煤储层的排采程度对CO_(2)注入的难易程度有重要影响,然而还缺少定量数据的支撑以及对CO_(2)注入及驱煤层气的效果的评价。借助数值模拟手段,以沁水盆地柿庄北区块SX018-5H井煤层气地质和工程条件为基础,构建了含1口水平井和2口直井的3号煤层CO_(2)-ECBM工区,设计了水平井排采0,1,2,3和4 a后,在1 a内连续注入万吨CO_(2),以及排采4 a后持续注入CO_(2)共计6个注入驱替方案,对比了10 a模拟时间内注入CO_(2)各方案及不注入CO_(2)方案的气井产出和储层动态变化情况。研究结果表明,在沁水盆地南部柿庄北区块3号煤层地质条件下,水平井具有较高的CO_(2)注气效率,3号煤层具有较大的封存潜力,注入万吨CO_(2)主要封存在水平井筒(长700 m)附近60 m范围内;煤储层的排采程度,也就是注入CO_(2)前储层的含气/含水饱和度,对CO_(2)注入有重要影响,储层中甲烷排采越充分,越有利于CO_(2)注入;CO_(2)注入对邻近煤层气井的生产存在增加储层压力的“负”效应和驱替甲烷的“正”效应。要在CO_(2)-ECBM项目中达到较好的驱替效果,一方面应增加煤储层的排采程度,另一方面应适当降低CO_(2)注入井和煤层气生产井距。
