OPENHOLE HORIZONTAL GRAVEL-PACK SYSTEM

Openhole Horizontal Gravel-Pack System applied for gravel-pack sand control completion in openhole horizontal wells, which can successfully accomplish the string tripping in, setting, testing, releasing, circulation, gravel pack, acid washing, tripping out etc. The designed string can maintain the pressure in horizontal wellbore, which is greater than that of formation, protecting the stability of openhole wall and ensuring smooth of the gravel pack operation.

◎ Applicable to 9-5/8 "casing + 8-1/2" open hole, 7 "casing + 6" open hole;

◎ Allows normal circulation and proper rotating to resolve the problem of tight trip quickly, when tripping;

◎ Packer of COHP with beginner diameter has reliable setting and hanging performance, and two-stage setting mechanism;

◎ Can bear load to prevent pipe moving and ensure the best filling result, when pack;

◎ Can keep the well bore clean after pulling the service tool from the hole at the end of pack;

◎ Can withstand 46MPa working pressure and 300 ℉ (150℃ ) working temperature, which could meet the requirement of rac-pack completion;

◎ Can provide API P110, API N80, API l80-9cr, API l80-13cr and other materials to meet the requirements of different working environments.
