RESEARCH AND APPLICATION OF PHYSICAL PRODUCTION TECHNOLOGY

For the most part of the low abundance, low permeability, and low production reservoirs in Jilin Oilfield,plugging is a very difficult problem in the immediate vicinity of wellbore during the late oil development period. Researchers of Production Technology Research Institute of Jilin Oilfield spent more than 10 years for the depth study of the way of solving the practical problems in oil production since 1988-2003, having achieved gratifying results in the physical broken down of the immediate vicinity of wellbore . They have got about more than ten injection technologies, such as acoustic, electrical, gunpowder, mechanical, hydraulic, etc. in many fields. Six of them are national patent technologies, the other two won CNPC second prizes, and 13 of them received the technical scientific and technological progress awards by Authority. Series of physical production technology was named "Forming Industrial Production Capacity" of outstanding scientific research projects by CNPC in 1996. Physical production technology has made significant economic benefits in field application. Up to the end of 2003, this technology has been applied to a total population of more than 2,000 oil wells, oil production has been increased by 143,000 tons, input-output ratio is 1:3.6. This paper mainly introduces the technoque principles and applications of four typical physical production techniques according to the frequency and amplitude of vibration.
