%X Sebei gas field is the fourth one in China. Its pay-zone is unconsolidation Quaternary fine-silty and dirty sandstones, alternating with gas and water layers, with severe sand production. Grain size of the sand is very fine, so sand control here is very difficult, it is cosmopolitan puzzle. We have succeeded in applying a series of techniques of comprehensive sand control using fiber-complex pack. The technique uses formation pretreatment (soft fiber, its branched chain with electric charge adsorbs on fine siltstones and forms big aggregations of fine siltstones.). special fibers and resin-coated sand complex to stabilize pack. Using high pressure pack to form the fiber complex annularity of well and to increase productivity, It bypasses near well bore damage. This combined rehabilitation technique enables screenless sand control completion. The technique was applied in Se 7-1-4 well; the results are remarkable. After the sand control treatment, sand was not found even the gas production rate is 2 1 times that of before. This paper presents lab study, operation design, well selection principle, field operation and result analysis about the sand control technique.
