  • In order to solve the carbonate pore and fracture leakage in the Tahe oilfield during the cementing process, a fiber leakproof cement slurry system was developed by selecting plugging mechanism and plugging material. The cement slurry system ALF-1 with fibers of 5, 10, 19 mm, respectively, was tested. When adding the cement slurry system ALF-1 with the fibers of 5 mm by 0.2%-0.3%, the cracks and pores of 1 mm were sealed very well, and could bear a pressure higher than 7 MPa. This system was applied in the tail pipe cementing in the well TP337X of the Tahe oilfield, solving leakage successfully during the whole process of construction. Amplitude logging showed good cement-ing quality.
