Study On Oil And Gas Accumulation Conditions Of Liunan Shallow In Nanpu Depression

This article guided by sedimentology, structural geology, petroleum geology, taking advantage of geological, geophysical exploration, well logging, logging and other information, probes into reservoir-cap rock spatial and temporal distribution, oil and gas reservoirs of the source rocks and oil and gas flow, reservoir and cap rock characteristics, reservoir formation dominant factors of shallow Liunan areas, optimization of oil and gas exploration zone, location of favorable structural traps, which has important reference value in further oil and gas exploration ofthe area.Paleogene Shahejie Set is the first set of sedimentary units of Nanpu concave,which is composed of three source rock tanks,these rock tanks offer enough resource of oil .And on the Shallow areas reservoir is of high porosity and permeability. Nm lower segment has a set of thick mudstone , together with tight basalt in Ngâ…£,being good cap rock of both regional and partial territory .And an excellent combination of the three mentioned above, which unconcealed existence of perfect basic conditions for forming a perfect reservoir. Therefore, the availability and effectiveness of the trap is the most important controlling factor during the process of accumulation.
