基于Iverson莫型的低渗透率油层压裂高度测井预测研究
The Logging-prediction of Low-permeability Reservoir Fracturing Height Based on Iverson Model
摘要
Abstract
Hydraulic fracturing is necessary for low porosity and low permeability sand-shale reservoir. This needs us to predict the fracture extending height in some given pressures to avert fracturing the surrounding rocks and control the fractures in the reservoir. Firstly, this thesis analyses how to know the height of fractures, how to sure the shape and azimuth of fractures and extend directions. Log data are used to forecast the formation stress and fracturing pressures and qualitatively analyse the fractures extendings. The fracture geometries are dependent on the formation stress and its direction. The fracture azimuth is vertical to the direction of the main minimum horizontal stress where the fracture extending height ends up. The modified Iverson model is used to forecast the fracturing height and process the post fracture responses. This method is used in fracturing process of Ordose Basin, and the fracturing result is below 15% than that of the post fracture detected height. The predicting result is consistent with that of fracturing and production, so the method can be used to guide the fracturing operations.关键词
