【 摘 要 】

Microsphere profile control is a new deep profile control technology in oilfield, which has developed in recent years. The particle size distribution of hydrated microsphere is an important basis for its application in formation pore throat, which has direct influence on the effect of profile control. First, the existing problems in current particle measurement of hydrated microsphere were studied through analyzing the results of the hydrated particle size, which were obtained from the static laser particle size analyzer. Results showed that there were two main problems in the current test methods of hydrated particle size. One was the poor reproducibility of the test results, and the other was the unrecognized particle size distribution of the truly hydrated microsphere. In addition, the test factors of hydrated microsphere particle size were studied through analyzing the morphology and the composition of microsphere. Results showed that the main influential factors of the hydrated particle size testing were the organic solvent and the emulsifier, which existed in the aqueous solution of microsphere with a variety of forms. Finally, some specific suggestions were put forward about the measurement of testing the hydrated particle size, which was removing the organic solvent and emulsifier from the aqueous solution of microsphere before measuring the hydrated particle size.
