Abstract： In order to increase storage and production of ϕ177.8 mm casing in Bohai Oilfield，a super one-trip multi-layer frac-packing sand control process was designed based on the increasing reservoirs with strong heterogeneity，long sand control sections，and thin oil reservoirs in Bohai Oilfield.Itcould achieve a 40O m flushing and displacement fracturing operation in a 5-layer sand control section in one trip.This technology has been applied in well PL19 3C30S4，completinga 389 m frac-packing operation in a 5-layer sand control section in one trip，with a maximum displacement of 3 m³min and a cumulative sand addition of 89.7 m³.The daily oil production has increased by 3 timesafter technological application，achieving the expected productionalocation. On -site demonstration applications have shown that this technology can reduce circulating friction，achieve multi-layer high-displacement frac-packing sand control operations in an ultra-long sand control section，effectively improve the underground flow environment，and increase oil well production.It has promotion and application value.
