Research and application of open-hole gravel pack sand control technique optimization in horizontal well

By the analysis of the reservoir, the fluid nature, the theory, the test of the formation sand, optimization of the technique design parameters of open-hole horizontal well gravel pack sand control is brought up in this paper. Results show that the significant effect can be appeared. The successful implementation of the technology has been greatly enhanced the level of sand control technology in horizontal well of Dagang Oilfield, and will be conduce to the development of the sea beach oil field which has a similar reservoir of the Bohai sea.
