| Abstract: | Well Banshen-7 is a wildcat well located in Banqiao area, its total depth is 5191. 96 m, and the BHCT and BHST are 145 C and 180 C respectively. Un-derbalanced drilling technology is employed for formation protection; thus it is necessary to use high temperature-resistant and low-density cement slurry for cementing. Suitable cement slurry is selected based on lab tests and the formulation is presented. The light cement slurry, which has a density as low as 1. 57 g/cm3, shows high compressive strength and adjustable thickening time, and it exhibits low fluid loss, minimal contamination and high temperature tolerance; gas migration and lost circulation is effectively prevented. Field test in this well is successful, and cement bond log shows an excellent cementing. |
