  • Loss of cement slurry into fractured formations is a problem often encountered and remained partially unresolved in cementing low pressure, fractured petroleum reservoirs. Foamed cement slurry, such as the chemically nitrogen filled foamed cement slurry is often used in dealing with this problem. Presently, the mechanisms of preparing the chemically nitrogen filled foamed cement slurry is not clear, and the efficiency of the chemical gas formers used is low. In this study the mechanisms of chemical nitrogen filling are revealed based on chemical thermodynamics and electrochemistry. A high efficiency gas former, LTPN, has been developed in preparing chemically nitrogen filled foamed cement slurry. LTPN basically does not affect the thickening time and compressive strength of cement slurry. When used in combination with animal protein foam stabilizer and nano foam enhancer, LTPN is able to reduce the density of cement slurry to 0.95 g/cm3. By extensively studying the chemical nitrogen filling pattern of gas formers in cement slurry, a high performance chemical nitrogen filled foamed cement slurry NFLC was developed. Cement operations of 30 wells have proved that NFLC is able to resolve problems encountered in cementing low pressure, fractured reservoirs. The cement slurry return height in cementing coalbed methane well with the NFLC cement slurry meets the designed requirements. In cementing the low pressure, fractured reservoir in Qinshui basin, Shanxi, cement slurry loss was avoided successfully, and the cement slurry returned to the designed height in the first try. 90% of the well was cemented with high quality. The chemically nitrogen filled foamed cement slurry has provided an effective way of cementing low pressure, fractured reservoirs, and has good application prospect.
