Study on Reservoir Characteristics of Ta112 in Songliao Basin

摘要

Ta34 in Songliao basin is buried 1,300 metres below the band, the exploration difficulty is big and high quality recognition is difficult. According to its complex lithology characteristics, poor porosity and strong heterogeneity, with the application of comprehensive conventional coring, thin-section analysis, scanning electron microscopy and conventional curve data for analysis of reservoir characteristics of T112, lithology and reservoir criterion are established, more over the fracture strata section of the hill is identified. The reservoirs are mainly composed of carbonate rocks and quartzite, the accurate lithology identification provides geological basis for the next step of well deployment.
