摘要
裂缝性气藏在世界天然气储量中占有十分重要的地位。裂缝性气藏裂缝是天然气主要的渗流通道,裂缝的分布和发育程度决定了气井的产能。以典型裂缝性气藏户部寨气田为例,运用叠后几何属性预测大裂缝和叠前各向异性属性预测小裂缝,综合分析裂缝预测结果,明确了裂缝的展布特征和发育程度,为优化井位部署提供了可靠的依据。
Fractured gas reservoir plays an important role in the world＇s natural gas reserves. Fractured gas reservoir is the main flow passage of natural gas, and the distribution and development of the cracks determine the gas well productivity. This paper to typical crack gas Ministry of the Tibetan village field as an example, using post stack geometric properties prediction fissure and prestack anisotropic properties predicted small cracks, comprehensive analysis of cracks in forecasting results, clear the distribution characteristics of the fractures and degree of development and the reliable basis is provided for the optimum well location deployment.
