The Eastern Sag Of Liaohe Oilfield Gold Belt-Ou Li Tuo Area Oil And Gas Geological Conditions Comprehensive Study

Gold belt – Ou Li Tuo area is located in panjin,liaoning province,the structure belongs to the eastern depression of liaohe basin,including gold belt,Yulou,the jehol,Ou Li Tuo four development zone of anticlinal structural belt,Er Jie Gou and Jia Zhang Si fracture flanks of forward and reverse ridge fault block zone.In general Gold belt – Ou Li Tuo area is a set of oil and gas formation,a variety of reservoir rock types of multiple oil-gas accumulation.There is still areas to further deepen the research,especially Es formation.Es sections for buried deep,complicated construction conditions,the overall is still low degree of prospecting and still has great exploration potential.But due to the work area data integrity and uniformity is poor,the drilling revealed Es is less,sand reservoir lithology is complex,non-structural reservoir seismic resolution precision limit,caused the block of sand body distribution,structure characteristics,favorable trap meet difficulties.This article carry out the gold belt-Ou Li Tuo area of oil and gas geological conditions comprehensive study,on the analysis of the seismic,drilling,well logging,mud logging,testing and testing,test data and the basis of the predecessors' research results,with 3d post-stack seismic data shall splicing processing technology,nonlinear space mainly wide-band well constrained wave impedance inversion processing technology and the new technology,new methods of advanced practical as the means,in petroleum geology,exploration geophysics,sedimentary geology,structural geology,develop geology and reservoir engineering theory as the instruction,adopts a multidisciplinary comprehensive research methods at the intersection of 3d seismic data of this area shall splicing processing and fine interpretation,give full play to the integration advantages,processing and interpretation of the structure,sedimentary,reservoir,reservoir type,oil and gas accumulation conditions and hydrocarbon accumulation in-depth,objective,system of the whole research,to predict the distribution of oil and gas layer,ultimately through the trap the synthetic evaluation of petroleum geology,optimizing favorable exploration targets,put forward the beneficial drilling target 9,9 locations are put forward.
