摘要

探讨煤地下气化热作用下盖层岩石（泥岩、砂岩）微观结构与孔渗、封闭性的演化特征．选取准噶尔盆地百口泉地区西山窑组泥岩与砂岩样品，采用扫描电子显微镜观测不同温度下（25～1 200℃）岩石微观结构变化；结合覆压孔渗和突破压力数据，分析热作用对岩石孔渗及封闭能力的影响．结果表明：（1）泥岩富含黏土矿物，其热响应主要表现为黏土矿物脱水、裂解及熔融，导致泥岩微裂隙扩展、新生裂隙增长；砂岩富含石英、长石，受热后以膨胀和矿物熔融为主，裂隙扩展，连通性增加．（2）覆压孔渗实验表明，泥岩孔隙度、渗透率在1～12 MPa范围内迅速下降，随后趋于稳定；砂岩的对应区间为1～16 MPa和16～36 MPa.900～1 200℃时，两类岩石孔隙度、渗透率均达到峰值，随后因矿物熔融堵塞而下降．（3）25～300℃时，泥岩突破压力因黏土矿物脱水骤降，砂岩因石英热膨胀适度增大；300～1 200℃时，两者随温度的升高突破压力剧降；温度高于600℃后，盖层岩石完全丧失封闭能力．

Abstract

This study explores the evolutionary characteristics of microstructure

porosity-permeability

and sealing properties in caprocks(mudstone and sandstone) under thermal effects during underground coal gasification.Using mudstone and sandstone samples from the Xishanyao formation in the Baikouquan area of the Junggar Basin

we observed microstructural changes in rocks at different temperatures(25～1 200 ℃) through scanning electron microscopy. Combined with overburden pore penetration and breakthrough pressure data

we analyzed the thermal effects on rock pore networks and sealing capacity. The results show that:(1) Mudstone is rich in clay minerals

and its thermal response is mainly characterized by dehydration

cracking and melting of clay minerals

which leads to the expansion of mudstone microfractures and the growth of nascent fissures. The sandstone is rich in quartz and feldspar

and when heated

it is mainly characterized by expansion and mineral melting

fissure expansion and increased connectivity.(2) Overburden pore penetration experiments showed that mudstone porosity and permeability decreased rapidly in the range of 1～12 MPa and then stabilized

whereas the corresponding intervals for sandstone are 1～16 MPa and 16～36 MPa. The porosity and permeability of both types of rocks peaked at 900～1 200 ℃

and then decreased due to the clogging of mineral melts.(3) At 25～300 ℃

mudstone breakthrough pressure plummets due to dehydration of clay minerals. Sandstone moderately increased due to quartz thermal expansion. At 300～1 200 ℃

both dropped dramatically with the temperature increasing. After 600 ℃

caprocks completely loss their closure ability.
