Experimental Investigation of Nature Gas Production Rate's Effect on the Reservoirs with Gas Cap

Abstract

Abstract-In order to study the effect of nature gas production rate on the reservoirs with gas cap, three-dimensional visualized gas-cap reservoir physical simulation device was established to simulate the processes of oil and gas development at different gas production rates. Monitoring and records of the interface migration law and well performance can be realized through visualization window. According to experimental result, it is shown that migration speed of oil-gas interface was reduced with increasing gas production rates while migration speeds of internal and external oil-gas interfaces gradually became close, which effectively slows down occurrence of gas channeling, reduces production gas oil ratio and increases the swept volume of gas drive, so as to improve its development effect. According to the optimization of collaborative development for gas-cap oil-rim reservoirs, the equivalence of accumulative production of oil and gas can reach the maximum value when the fixed period of reservoir exploitation is 50 years and the gas production rate is between 2% and 4%.

Removal of Sulfur Compounds by a Copper-Based Metal Organic Framework under Ambient Conditions

“…Natural gas, a hydrocarbon clean fuel, was widely used in residential, commercial, and gas vehicle applications. , In recent years, fuel cells have received more attention recently because of their high conversion efficiency and low emissions . Natural gas is regarded as an important and convenient hydrogen source for fuel cells because of its abundant reserves and wide distribution .…”

Modification of a Copper‐Based Metal–Organic Framework with Graphene Oxide for the Removal of Sulfur Compounds

“…Natural gas, a clean source of energy, has a high calorific value and high utilization efficiency and is used widely in industrial production and for civilian use . However, it must be purified before use as it contains impurities, especially sulfur‐containing compounds such as hydrogen sulfide, mercaptan, and carbonyl sulfide, which create great environmental pressure .…”
