Main Fields of Oil and Gas Exploration and Problems

Abstract

With the strengthening of oil and gas exploration, the more and more complicated prospecting targets and the more deeper the more complicated of structure’s controlling effects on oil and gas basin formation, it can be shown from lithostratigraphic trap increasing, the ratio of unconventional reservoir increasing, prospecting target becoming smaller, and the ratio of deep targets increasing. It is urgent to solve these problems with new knowledge and technology; at the same time, technology reserve and basic material for developed basins can hardly satisfy with the present demand. Seismic acquisition configuration and wellbore test is relatively out of date, and it fails to make a systematically comprehensive cognition and exploration of complicated block fault and lithologic hydrocarbon reservoir, and limits the deepening of maturing oil field exploration. Therefore, it is urgent to deepen the study of continental basin remaining resource potentiality and petroleum geology rules. The main prospecting target for continental basin is concentrated on the basin litho-stratigraphical hydrocarbon reservoirs, low porosity-low permeability reservoirs and deep reservoir.
