There has no the ability of generating oil and gas in the shallower strata of Dongpu sag. Developed as one of the most important transporting body, the sandstone connects deeper hydrocarbon source rocks and shallower trap, so sandstone transporting capability directly determines if or not the hydrocarbon accumulation can happen in the shallower strata. The evaluation of sandstone transporting capability is one of weak links in the study of transporting body; the micro-transporting characteristics determine quality of sandstone transporting capability. Since there has defects in microscopic property measurement techniques of conventional sandstone, this paper by means of the measuring software on pore diameter named Scandium in scanning electron microscope for the first time, the sizes of pore and throat of shallower strata in Dongpu sag are distinctively measured systematically in microscopic scaling. Then the longitudinal distributing characteristics are summarized.
