DEVELOPMENT TECHNOLOGY OF LOW PERMEABILITY OIL RESERVOIRS IN SHENGLI OILFIELD

Low permeability oil reservoirs are one of the vital oil resources in Shengli Oilfield.Enhancing development technology and making a good use of the kinds of reservoirs are very important to the stable and sustainable development of both Shengli Oilfield and the whole industry of our country.Shengli Oilfield has made great progress on study of features of reservoirs,technologies of slim hole drilling,horizontal well drilling and hydraulic fracturing.New acknowledgement has gained on reservoir flow mechanism through porous media,gas injection miscible flooding technology.Research direction of development technology in the near future should focus on detailed studying on reservoir flow mechanism through porous media,gas injection miscible flooding and immiscible flooding,studying and introducing international advanced fracturing technology and materials,studying flow mechanism of extralow permeability oil reservoirs and water flooding technology so as to enhance reserves productivity and utilize oil resource effectively.
