摘　　要：从天然裂缝、地应力及水力压裂等方面简要地论述了蒙古Toson Uul油田地应力分布特征及裂缝发育特征。通过实际资料,详细分析了油田天然裂缝发育程度以及水力压裂裂缝展布规律,提出适合油藏特征的开发方式。研究成果对加深油田储层裂缝认识,指导油田制定合理开发方式以及开发后期调整具有重要意义。In this paper, the characteristics of stress distribution and fracture development has been discussed through the analysis of natural fractures, stresses and induced fractures in Toson Uul oilfield, Mongolia. The development degree of natural fractures as well as the distribution features of induced fractures have been clari- fied and the optimal development methods have been proposed on the base of data from stress analysis, coring and fracturing practice. The results are beneficial to the understanding on fracture development law of the reservoir, the design of optimal development method and further development adjustment.
