A number of problems relating to pay zone with high pressure, serious leakage, narrow pressure window, and easy gas migration existed in casing and cementing of the pay zone in a high pressure gas field in West China. To prevent leakage, the density of cement slurry could be higher than the density of mud slurry by only 0.02g/cm3, but generally it should be the cement slurry with high-density higher than 2.25g/cm3.
The application of this system has solved many problems as mentioned above, and the statistics showed that the cementing quality has been improved from poor in the whole section ~ best by 58% originally to excellent by 75% ~ best by 100% currently.
