Abstract


Tight oil resources in north Songliao basin is rich and abundant, which is the most important energy sources foundation of Stable and raising oil production in Daqing oilfield. However, it is difficult to develop such oil resources by the regular ways and has no economic benefit for the poor reservoir property and thin reservoir thickness. Using the way of horizontal well by volume fracturing can reach the high oil production, which has showed good results up till now. But now tight oil in Daqing oilfield exploration and development is still in its infancy, the pore structure and seepage flow law of tight oil reservoir in north Songliao basin is not clear, which is potential barrier for exploring tight oil reservoirs effective development mode. Tight oil reservoir single phase and two phase fluid seepage rule are researched by means of theoretical and experimental, the results of which can provides a reliable theoretical basis for tight oil reservoir developed effectively.
