Based on the statistical data of the oil sand control in Bohai Bay area, it is found that sand production in many oil wells is uncontrollable due to the indiscriminate use of high quality screen. This paper develops a gravel pre-packed sand control screen by combining the characteristics of present wire wrapped screen(WWS) and mesh screen(MS). Based on the statistical result of formation characteristics in Bohai Bay Basin, a large amount ofsand control simulation experiments are reported in this paper. Principally we analyse the characteristics of formations and drawdown pressure. The results show that: • Shale content has the biggest influence on the blockage of screen, when it ranges from 5% to 10%. The fluid productivity index per meter (FPIPM) of the former is 2.5 times higher than the latter with shale content equal to 10%. It is only a temporary solution to adjust the drawdown pressure for improving the production but this does not provide along term solution. • Sand control design methods of Tiffen, George Gillespie and Johnson have a lot of limitations with reasonable sanding of Bohai Bay. When the uniformity coefficient (UC) is greater than 5, fine grain content ≫5%, pre-packed screen can be used effectively in sand control. • When comparing the pre-packed screen and independent high quality screen commonly used in field, we find the pre-packed screen has a wider adaptability to the formation, so it can better meet the sand control requirements in the field.
