Abstract: Analyzing the sanding mechanism in Minghuazhen Formation， Nanpu 35–2 Oilfield， the logging data
are used to calculate the rock mechanical parameters， such as cohesion， angle of internal friction， elastic modulus，
Poisson ratio and maximum level principal stress. Then the methods of sand factor and Schlumberger are applied
to forecast sanding and calculate the critical drawdown pressure. Based on the sanding forecast method and the
model of critical drawdown pressure， the reservoir sand production index profile and the critical drawdown pressure
profile are compiled. Calculation results show that the possibility of Minghuazhen Formation sand production is
high. Research results provide quantitative basis for defining sand production in this block and the nearby， and
guidance for reasonable formation of oil well work system.

Key words: log information, sanding prediction, sanding factor, critical drawdown pressure, rock mechanical pa-rameters
