摘要： 岩石力学实验和深井钻探结果表明, 在沉积物固结成岩或岩浆冷凝成岩以后, 如果地层因溶蚀作用发育较高的孔隙度,这样的储集层不会因上覆地层压力而损失其孔隙性, 如果不存在强烈的胶结作用, 这种岩石孔隙可以在7~8 km 甚至更深的条件下得以保存。因此,深部和超深部地层也可发育高质量的油气储集空间。

Abstract: Resultsfrom rock mechanics tests and deep well drilling revealed that after sediments solidified into sedimentary rocks or magma condensed to igneous rocks, if the strata developed with higher porosity by dissolution, then such reservoir rocks can not lose their porosity due to overlaping formation pressure.If there is not large scale of cementation, the higher porosity of the rock can be preserved in the place over 7 000 ~ 8 000m in depth. Therefore, deep and super deep strata can also develop with high-quality oil and gas reservoir spaces.
