摘要: 分析了渤海南堡 35–2 油田主力储层明化镇组的出砂机理, 应用测井资料 (纵波时差、 横波时差、 伽马
和密度等) 建立了黏聚力、 内摩擦角、 弹性模量、 泊松比和最大水平主应力等岩石力学参数的求取方法, 并在
此基础上应用出砂指数法、 斯伦贝谢法进行出砂预测以及临界生产压差的计算。根据出砂预测方法和临界
生产压差的计算模型绘制了储层出砂指数剖面和临界生产压差剖面。计算结果表明, 明化镇组储层开采过
程中出砂的可能性极大, 开发时应采取防砂措施。研究结果为今后该区块及附近区块油井出砂界定提供了
准确的量化依据, 可为油井合理工作制度的制定提供指导。

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
