Du 301 Block Of Liaohe Oilfield Dujiatai Reservoir Research

Dujiatai reservoir of Liaohe Basin in Huanxiling oilfield in Liaohe fault basin in the western depression in the west slope of southern fault nose structure belt, with low porosity,low permeability and strong heterogeneity. After 20 years of development, measures yield decreased, interlayer contradictions have become increasingly prominent, the remaining oil distribution is complex. Therefore, it is necessary to reservoir study of the reservoir, offer the basis for tapping the latent power in the old liberated areas of remaining oil.Through studies confirm that the main source of sediments in the study area in the south-west, Du Jia Tai Group reservoir sedimentary period for fan delta facies, fan delta front sub phase, and the division of underwater distributary channel and distributary channel,debouch bar, front sheet sand and far sand dam etc. microfacies. Making use of the regional geologic research results, combined with a large number of logging data, determine the section layer on the reservoir pore genetic types; through the analysis of reservoir make classification and evaluation, and then gradually drilled exploratory wells were drilled Dujiatai reservoir, the description of the block Du Jia Tai oil conventional production has a certain production capacity.
