Abstract: In order to perfect the nearly presented partial technology in new mode of effective development of offshore heavy oil field,that is the drilling and production support technological system which takes drilling fracturing well,limited sand production and electric submersible progressive cavity pump as main technologies,according to the skin factor model and productivity model of drilling fracturing well with different completion ways including barefoot completion,perforation completion and screen pipe completion etc,the influence of different technology parameters of different completion ways on reasonable sand production well is researched.The result indicate these parameters impact the physical property of sand production belt and thereby the oil well productivity to some extent.It is necessary to strictly estimate the influence of completion ways and its technological parameters on the physical property of sand production belt and thereby on the oil well productivity.

Key words: well completion way, reasonable sand production, drilling fracturing, skin factor, productivity
