摘要

深埋变质岩潜山风化壳相对致密，裂缝发育程度是储层优质的决定因素。利用岩心、铸体薄片、荧光薄片、扫描电镜、常规物性等实验分析方法，对渤海海域渤中19-6构造太古界深埋变质岩潜山优质储集层形成机制进行分析。研究表明，渤中19-6构造太古界以片麻岩、变质花岗岩和混合岩为主，岩石中长英质矿物含量高、地层脆性强，极易形成裂缝，为优质储集层的发育创造了较好的岩性条件；持续动力破碎作用使潜山内幕发育大规模裂缝发育带和动力破碎带，是变质岩优质储集层形成的关键；风化作用影响下潜山顶部形成大量次生溶蚀孔和沿裂缝溶蚀扩大孔，但深埋作用使顶部风化壳相对致密。在上述控制因素指导下，建立了“垂向贯通，横向连续”大型深埋变质岩优质储集层分布模式。

Abstract

The weathering crust of deep metamorphic rocks is relatively dense

and the development of fractures is key to reservoir quality.The formation mechanism of high-quality buried-hill reservoir of deep Archaean metamorphic rocks in the BZ 19-6 structure was analyzed through core description

casting thin section observation

microscopic fluorescent analysis of thin section

scanning electron microscopy and conventional physical property measurements.The results show that the Archaean rocks in the BZ 19-6 structure are dominated by gneiss

metamorphic granite and migmatite

in which the high content of felsic minerals with great brittleness is prone to fracture development.Thus

they tend to develop high-quality reservoirs.The fragmentation under continuous deformation and stress makes large-scale fracture zones and stress fragmenting zones developed inside the buried hill

which is the key to the formation of high-quality reservoirs in metamorphic rocks.The weathering resulted in a large number of secondary dissolution pores and dissolution enlarged pores along fractures on top of the buried hill.However

the weathering crust became relatively dense under deep burial.Under the guidance of controlling factors mentioned above

a reservoir distribution pattern of "vertical connectivity

and lateral continuity" is revealed for large-scale deep metamorphic reservoirs of high quality.
