Abstract: China’s continental tight oil reservoirs were mainly two types that originated from saline lake and fresh water lake.The saline lake tight oil reservoir looks like blanket structure, which composed fine clastic rock with carbonate.Its compressibility was close to that of North American marine tight oil reservoir, with poor fluidity of crude oil and strong heterogeneity of formation.The fresh water lake tight oil reservoir likes blanket or box structure, including mainly sandstone and shale, with poor compressibility, varied pore pressures and different fluidity of crude oil, more sensitive to engineering parameters.On the basis of analyzing the developing status and problems of China’s continental tight oil, a proposal was presented for development of tight oil that "taking the reservoir engineering as guidance, with good foundation, reversed thinking, diagnosis and treatment, continuous innovation, a complete of technologies integrated, rolling development of it from easy to difficult operations".Different types of tight oil reservoirs should be developed in different modes.The key technologies should be researched, including sweet point description and evaluation, the theory of drilling the limit, coordinated with geo-steering drilling, fine composite fracturing, the performance of tight oil changed inside the reservoir, integration of fracturing and production, etc.
