ADAPTIVE LOGGING INTERPRETATION MODELS FOR ROCK MECHANICS PARAMETERS

岩石力学参数是解决井壁失稳、水力压裂、出砂预测等石油工程问题的基础。提出了自适应岩石力学参数测井解释模型,解决了模型在工程实际应用中产生的区域性和层位性问题,结合改进的计算方法能更准确地预测压裂地层岩石力学参数。建立的水力压裂岩石力学参数计算方法更全面地考虑地层条件,具有更高的计算效率,适合现场进行水力裂缝几何形状模拟压裂施工优化设计及增产预测,同时也为出砂预测等石油工程问题提供基础数据。

Rock mechanics parameters are the basic data for petroleum engineering problems,such as well bore instability, hydraulic fracturing, and sanding prediction, to be successfully handled . The adaptive logging interpretation models are overcome local limitation and interval difference for field application, and can be more exactly predicted rock mechanics parameter through improved computing method. These parameters are suitable for hydraulic fracturing stimulation, hydraulic fracturing optimization design and incremental productivity prediction, and also provide the basic data for sanding prediction.
