This paper introduces sand-control troubles that restrict efficient exploitation of Sebei Gas Field (SGF).Through comprehensive utilizations of sand-stacilization, sand-consolidation and sand |control technologies, the HRWP and fibered Frac-Pack technologies are showed t he optimization solutions for sand-control jobs of high-clay fine siltstone in SGF. These two technologies have been implemented on 47 wells until now. Most o f wells after sand-control job, with the average gas-production increase of 40 percents ,and the maximum effective period up to 3 years. These data show that these two technologies can meet the sand-control demand of the fine-siltstone reservoir and the demand of further promoting well production.
