摘要
介绍了次生孔隙成因机制的四种假说。论证了深部储层具备产生耗散结构的一切条件 ,指出初始强酸性含矿深部热流体是形成次生孔隙的主要因素之一 ,阐述了脉动性深部热流体双扩散循环对流机制 ,提出了深部热流体耗散结构形成机理 ,解释了渤南洼陷沙四段异常地质现象。
Four hypotheses of secondary pore forming mechanism are introduced. It is proved that the deep reservoir has possessed all conditions of dissipation structure, pointed out that the deep hot mineral fluid possessing initial strong acid is one of the main factors of secondary pore formation. The double diffusive circulative convection mechanism of deep pulsating hot fluid has been expounded. Forming mechanism of the dissipation structure of the deep hot fluid is pointed out. The abnormal geologic phenomena of Es 4 in Bonan subsag have been explained.
