Effect of mixing condition on the rheological behavior of cement slurry

In field cementation, the displacement flow rate is determined by laboratory test data, because of different mixing condition in cement slurry creation, the slurry rheological behavior would vary. A test program was conducted to verify the difference between laboratory test and field test. The test data show that, cement slurry made in field test by cementing truck behaves in shearing thinning more strongly than that from laboratory test. The test data also show that the mixing energy in laboratory test is lower than that of field test, resulting in a calculation error in pumping rate of displacement prediction by laboratory test data. Based on the test program, a conclusion could be reached that mixing condition would affect the slurry rheological behavior.
