摘　　要：以系统科学理论为指导,探讨了储层损害的一般规律,揭示了储层保护技术系统的环境和结构特点。明确了储层损害源是一个复杂的系统,而且储层损害作用过程也是一个系统,从而决定了储层损害的评价、诊断、预防、处理改造还是一个系统。储层保护各项技术原则的制订和配套工艺的实施都应从系统工程角度出发,对技术进步、经济效益和环境保护要统筹考虑。介绍了已形成的储层保护技术系列,并以川西裂缝性致密砂岩气层、吐哈低渗透砂岩多套油层和渤海高渗透疏松砂岩油层为例,说明了储层保护系统工程的成功应用。讨论了储层保护理论研究和实践中存在的问题,指出思想观念、组织协调和工程运作等仍是制约保护技术实施和最终效果体现的重要因素,促进观念更新、加强技术培训仍任重而道远。The permeability impairment of the reservoir formations is investigated under the guidance of systems theory and environmental and structural characteristics of the reservoir permeability preservation are revealed. It is understood that the source of permeability impairment is a complicated system and the process in which the permeability of the reservoir formations is also a system, thus without doubt that the evaluation, diagnosis, prevention and removal of the formation permeability damage form another system. The development of and application of the technology in reservoir preservation and the combined techniques should be done under the guidance of the systems engineering, and technology progresses, economy and environmental protection should be compromised. This paper discusses the mature technology in reservoir permeability preservation; take as samples the fractured tight gas sand in west Sichuan, the low-permeability sand reservoirs in TuHa Oilfield, and the high-permeability loosely compacted sand reservoirs in Bohai Bay to introduce the successful application of systems engineering in reservoir preservation. The problems existed in the study and application of reservoir preservation are also investigated, and points out that ideology, organization, coordination and engineering operation are the important factors in controlling the application of the technology and the realization of the final benefits. Many work has yet to be done in the rejuvenation of the ideology and technical training.
