Research On The Geological Characteristics And Formation Regularity Of Oil Sands In The Northwest Ditch Of Zhenlai, Jilin Provinece

Oil sands is a kind of sand or sandstone containing pitch or tar,95%of which isconcentrated in Canada and accounted for about30%of the world’s oil reserves.Most of Chinese oil sands distribute in several main large basins, with increasing ofglobal oil demand and development of oil sands mining and metallurgy technology,oil sands has gradually become an important unconventional petroleum resourcesavailable.In this paper, the Zhenlai’s northwest ditch mining area in the west slope zone ofSongliao Basin is used as a research object for the first time, studying the geologicalcharacteristics, metallogenic regularities and forecasting the periphery. In this study,on the basis of data collection and northwest ditch mining area as the breakthroughpoint, via a comprehensive analysis for data received from geological drilling,geophysical exploration, geochemical exploration, logging and a large number ofindoor test, we summarized the geologic feature of oil sands in Zhenlai that the oreseam is stratified discus-shaped, consequent landslide, south-inclining small angle andgradually deepening; furthermore, the oil rate is relatively high as high compositionof silty, and ore body is relatively stable. Presenting that celadon oil siltstone of deltafront facies in Yaojia formation is the most direct ore-prospecting criteria, as well asthe surrounding is forecasted, and provides a train of thought for later work.
