本文论述了用二维和三维模拟水力压裂试验的结果,包括:1.压裂所形成的裂缝特点的分析和研究;2.破裂压力与地应力的关系;3.裂缝形态随地应力的变化关系;4.对我国某些油田部分油层岩石力学参数的测定方法和测量结果。本文根据试验结果提出了“震动压裂”的概念,初步探讨了提高压裂增产效果的新途径。
This paper discusses the results of two-dimensional and three-dimensional simulation of hydraulic fracturing tests, including: 1. Analysis and research on the characteristics of fractures formed by fracturing; 2. The relationship between fracture pressure and geostress; 3. The variation of fracture morphology with on-site stress Relationship; 4. Some of China’s oilfield oilfield rock mechanics parameters of measurement methods and measurement results. Based on the test results, this paper puts forward the concept of “vibrating fracturing” and explores new ways to improve the effect of fracturing stimulation.
