THE THREE-DIMENSIONAL FINITE ELEMENT NUMERICAL SIMULATION OF MODERN STRESS FIELD AND ITS SIGNIFICANCE IN THE OIL DEVELOPMENT OF THE JING'AN AREA IN THE CENTRAL SHAANXI-GANSU-NINGXIA BASIN

摘要: 本文在建立合理地质模型、力学模型和数学模型的基础上,用三维有限元数值模拟方法对靖安地区三叠系延长统现今应力场的分布进行了计算。它们对该区开发井网布置、压裂改造方案和水平井的设计以及注水管理有重要指导作用。

Abstract: On the basis of the establishment of geological, mechanical and computation models for the Jing'an area, the spatial distribution of modern stress field in the Yanchang Series of Triassic System in the area has been studied by the three-dimensinal finite element method. The results will have an important bearing on the disposition of oil wells, plan of modification of hydrofracturing and the design of horizontal well and water injection management.
