The petrophysical properties of volcanic rock reservoirs in junggar basin are generally characterized by the following : the acidic lava and auto brecciated lava are the best , especially the petrophysical properties of auto brecciated lava and andesites after the tectonic movement and denudation process in the later stages are superior to those of basalts 準噶爾盆地火山巖儲層物性一般特點是:酸性熔巖、火山角礫巖最好,特別是經后期構造運動和溶蝕作用改造后的火山角礫巖;安山巖的物性總體優于玄武巖。

( 2 ) based on indoor test , two typical soft rock of brecciated mudstone and siltstone in luohu jiancheng district is carried systemically though interior rheological testing ; moreover combining with preceding studying results of rock rheological constitutive model , rheological numerical constitutive model suited to rock mass mechanics characteristics and stratum structure of luohu fracture zone , and numerical parameters of the model are processed with studying of curve fitting ( 2 )立足于室內試驗,對羅湖建成區兩種典型的軟弱巖石?含角礫泥巖和粉砂巖進行系統的室內流變試驗研究,又結合前人對巖石流變本構模型的研究成果,分析并確定了適合羅湖破碎帶巖體力學特性及地層構造特征的流變計算本構模型,并對該模型的計算參數進行了曲線擬合研究。

There are typical laminated structure , soft sedimentary - slipping deformed structure , syngenetic brecciated structure in the ore which are the mirror of syngenetic sedimentation . the other type of ore has the charactristic of epigenetic mineralization , which is called as telescoped ore . the ore occurs in vein , pocket , lensoid and bedd 礦石中發育典型的紋層狀構造、軟沉積滑動變形構造、同生角礫構造等反映同生沉積特征的礦石構造;另一類礦石具有明顯的后生成礦特點,稱之為疊生改造型礦石,礦石產于脈狀、囊狀、透鏡狀及似層狀礦體中,與燕山期巖漿巖及斷裂裂隙構造關系密切。
