大地热流值是表征地球热状态的重要参数,也是进行深部地温预测和评价一个地区地热资源的最基本数据。受钻孔测温的影响,盆地外的无钻孔测温地区缺少实测的大地热流值。目前的热流分布图都是依据相邻盆地的实测值进行插值绘制的,无钻孔区热流值可信度较低。由于岩石居里点与温度密切相关,可以通过居里面深度来研究地表热流值。本文依据东北地区现有的居里面深度分布图,结合实测的岩石热导率、岩石生热率数据和相应的地壳分层状况,计算了东北地区的大地热流值,重新绘制了中国东北地区精细的大地热流分布图。东北地区整体大地热流处于42.5~95 mW/m~2之间,热流高值位于五大连池及敦化-密山断裂带海龙—牡丹江一带,松辽盆地内部、小兴安岭和长春-延吉缝合带也有局部的高热流值。热流高值与居里面隆起区域有较高的一致性,即居里面隆起处热流较高,而坳陷区热流较低。本次研究填补了中国东部地区热流实测值空白,为该区深部地温预测和地热资源评价提供了更加准确的参数。

渤海湾盆地的大地热流高,5000 m埋深地层平均温度为175℃,热储岩性以低孔低渗的变质岩、火成岩为主,具备形成干热岩资源的条件。基于大地热流、岩石热导率、生热率等热参数,利用COMSOL软件建立三维水热耦合的干热岩开采模型、分析不同井间距、注采速率、布井方式等差异开采方案下在100 a内对热储层温度的影响随开发时间的变化,选取最优方案并估算干热岩资源。结果表明:注采速率一定时,随着开采时间的增加,开采井水温度下降速率与井间距成反比;当注采井间距一定时,注采速率越大,开采井水温度下降越快,发生“热突破”的时间越早;其他条件相同的情况下,“两采两注”布井方案比“一采一注”布井方案获得的热量更多,开采效率更高。基于上述认识,确定研究区最优开采方案为:年限50 a、井间距400 m、注采量90 m^(3)/h、“两采两注”方式。此方案下,可获得开采井水平均温度为172℃,对应全渤海湾盆地可采资源量为3.28×10^(19)J/a。以河北任丘市为例,按照民用住宅热负荷指标100 W/m^(2)计算,利用最优方案进行干热岩的开采,仅需157.75 km^(2)干热岩有利区即可满足全市居民供暖需求。因此,开发利用研究区干热岩资源,可增强华北地区能源供应保障能力,打造可持续发展的绿色低碳能源体系。

二叠纪峨眉山大火成岩省岩浆喷发是我国显生宙最大的岩浆喷溢事件。四川盆地中二叠世最新油气勘探成果显示,在峨眉山大火成岩省北缘成都简阳地区,发育大量以火山碎屑岩为主的全新岩性格架。本文首次对该区域岩性格架展开了详细的火山学解译。在优势储集层段中识别出熔结凝灰岩、自碎裂角砾岩和溅积集块岩三类关键岩性,分别形成于溢气爆发陆上火山碎屑流机制、溢流喷发自碎裂角砾化机制以及斯通博利夏威夷涌溅式喷发机制。这是首次对峨眉山大火成岩省中上述岩性的成因机制进行正式确认。在这些岩性中,储集空间以溶蚀孔和交代孔为主。上述岩性的喷发机制,对其储集空间的发育提供了全方位的关键制约因素:(1)有利于产生大量浆源碎屑;(2)堆积方式有利于维持大量相互连通的原生孔隙,使热液流体得以广泛接触碎屑堆积骨架;(3)堆积于火口近源区域,受异常热流值作用强,有助于维持流体的高效活性。上述三方面最终导致流体对岩石骨架进行深刻的溶蚀交代改造,为规模性储集体发育奠定前提。

盆地古温度场与地热、油气资源的形成演化密不可分。为明确松辽盆地关键时期的古地温场特征,以实测的269块样品热导率和汇编的前人数据为基础建立热导率柱,并以镜质体反射率Rran为约束进行多口单井的埋藏史-热史模拟。结果显示,松辽盆地平均热导率为1.79 W/(m·K),热导率随深度增加而增大,在上部地层中增大的速率大于下部。热导率随地层年龄增大而增大。松辽盆地北部Rran主要在0.8%~1.6%,齐家古龙凹陷Rran最大。埋藏史-热史表明,白垩系青山口组地层在明水组末期达到最大古地温,然后至今呈逐渐降低的趋势。古地温场平面分布显示松辽盆地北部青山口组地层在大部分地区的最大古地温达到120℃以上,显著高于现今地温场。青山口组从沉积后进入盆地热沉降发育阶段,随着古埋深的增加,古地温逐渐增至最大。此时较高的古地温条件能够促进页岩油气的成熟。明水组末期受古太平洋板块运动影响,发生了显著的抬升冷却事件,在冷却过程中温度梯度降低幅度较小的地区形成了地热温度条件有利区。研究成果可为松辽盆地地热、油气资源的形成机理研究提供理论参考。
