Factors influencing the physical properties of reservoir in the Qing 1 section of Daqingzijing Oilfield
摘要
Abstract
In order to study the effects of geological processes on the physical properties of ultra-low permeability reservoirs,find out the main factors influencing the reservoir physical property and im-prove the success rate of oil and gas exploration,based on core observation,statistics of core physical properties data and thin section identification,six factors which are lithology,deposition,dissolution,ce-mentation,structure and depth were selected,using geological statistics and correlation analysis of pa-rameter crossplot methods,the factors influencing the physical properties of reservoir in the Qing 1 sec-tion of Daqingzijing Oilfield were systematically studied.The results indicate that the physical property of reservoir in the study area have some differences,and show the characteristics of the low pore-extra low porosity,low permeability-extra low permeability.Lithology and sedimentary facies are the most im-portant main control factors of reservoir property,fine sandstone is better than other lithology,the physi-cal property of reservoir in sediment source area is better,but the physical property of reservoir in sedi-mentary frontal area is relatively poor.Dissolution and cementation have a large effect on reservoir phys-ical property.Only near the fault,tectonic setting can improve the permeability of the reservoir,and away from the fault of well block,the reservoir property is almost not affected by tectonic action.With the in-crease of buried depth,the decrease trend of reservoir porosity and permeability are not obvious,and it shows that the buried depth is of less affect on the physical property of reservoir.关键词
