Abstract

To solve the challenges in the cementing of ultra-deep high-temperature and high-pressure (HTHP) gas wells, a latex cement slurry system with good high thermostable anti-gas channeling and elasto-toughness performances was developed, which uses the styrene-butadiene latex DC200 to enhance the anti-channeling performance of cement slurry and reduce the permeability of set cement, and additionally use modified elastic particles, organic polymer fibers and inorganic mineral fibers as composite toughening materials to enhance the elasto-toughness of set cement effectively. The evaluation results show that the temperature resistance of this system is above 160°C, the SPN value is <1, and the static gelling strength transition time is only 12 min, indicating a good anti-channeling performance. Compared with the conventional set cement, the permeability was reduced by about 80%, the elastic modulus was reduced by about 60%, the bending strength was increased by about 84%, and the impact resistance of set cement was increased by about 86.69%, showing excellent mechanical properties. This system has been successively applied in well SHN-401 and well SHN-4-1 in Tazhong Oilfield, and the overall cementing quality was good. It proves that this cement slurry system can meet the cementing technical requirements for ultra-deep HTHP gas wells, and has good application prospect.
