| 中文摘要: |
| 本文以贵州正安地区A区块页岩气储层为研究对象,结合地震解释、钻井资料、测井数据等资料,运用petrel三维建模软件,建立正安地区A区块页岩气储层三维构造模型、三维地质力学模型及天然裂缝模型,对储层构造形态及天然裂缝的几何分布特点进行表征;在模型基础上,考虑应力阴影、天然裂缝分布特征、支撑剂沉降及运移,结合实际施工情况进行正安地区A区块人工裂缝扩展数值模拟并开展压后产能数值模拟研究,总体模型拟合率较高;该类页岩气藏模型的构建方法和实际应用,可为同类气藏的开发提供借鉴。 |
| 英文摘要: |
| This papaer deals with the shale gas reservoir in Block A, Zheng’an area, Guizhou Province. Software petrel is applied to build 3D models of data from seismic interpretation, drilling, well logging data etc., such as the 3D structural model, 3D geodynamic model and natural fracture model of the shale gas reservoir. Then the reservoir structural morphology and the geometric distribution characteristics of natural fractures were characterized. On the basis of the above 3D models, the stress shadow, natural fracture distribution characteristics, proppant settlement and migration and the actual operation the numerical simulation of artificial fracture expansion in block A of Zheng’an area and the numerical simulation of post-compression productivity were carried out, and the overall model fitting rate was high. The construction method and practical application of the shale gas reservoir models can provide reference for the development of similar gas reservoirs. |
