Oil And Gas Geologic Conditions Research Of Nangong Sunken At Mesozoic And Cenozoic

NanGong sunken is located at JiNan area,in the center of the Plain of North China. On the structure NanGong sunken underneaths LinQing depression and is retained between XinHe uplift and MingHuazhen uplift.Under control of the MingHuazhen fault,it's an estern fault and western overlap, constringes at QiuXian sunken and extends at orientation of NNE. The original researches the original,finds out miscellaneous geologic feature of oil and gas, stratigraphic distribution and structural control in the region of interest.It also primarily appraises geology foreground of oil and gas.At the side of the structure:From the analyse of the structural feature of LinQing depression,it researches the structural location of the region of interest in LinQing sunken,divides structural units,researches structural layers at bound of the regional unconformity surface or tectonic movement surface,and compares with conterminous area. It researches the secondary structural feature, stressly analyses the course of the structural evolution and structural control basin and structural control facie. At the base of the analyse of structural evolution, It stressly analyses that the tectonic movement affects stratum's save and generating rock's save.At the side of the stratum:It enough collects the diversified geologic information of NanGong sunken an conterminous area and establishes stratigraphy system at the meams of comparative analysis and structure- stratum analysis. It stressly researches the stratum's distribution at Mesozoic Era and Early Teriary.At the base of the analysis of stratum's era and sediment feature,it detailedly finds out the types and distribution of the precipitation facies of NanGong sunken, utilizing the sedimentological thinking of basin's bulk analysis and precipitation systems as three-dimensional space entity.At the base of the research of structure and stratum,It analyses the generalized geologic conditions of oil and gas, detailedly researches the different layer systems'development feature, distribution range and generating heart of generating rock and synthetically evaluates different layer systems'generating rock.At the base of the researches of regional geology,It researches the palaeogeothermal,structural evolution of heat's mechanism and effective mechanism of generating rock. It researches an analyses reservoir-covering strata condition and the association of generating rock- reservoir-covering strata. Finally it appraises the reservoir condition and prospecting foreground and forecasts important prospecting erea.
