摘　　要：绥靖油田三叠系高水饱低压低渗油藏的典型代表为化子坪长2油藏。本文针对此类油藏储层物性差，非均质性较强，油水分异差，原始地层压力低，饱和压力低，自然能量不足，油井投产后含水高，产量低的地质特征与开发特点，在对储层地质研究的基础上，运用理论结合实践、经验法、类比法等研究方法探讨了这类油藏地层压力保持水平、流动压力、注水强度、采液强度等开发技术政策，并应用这些政策对化子坪区块进行了调整，取得了较好的效果，同时为这类油藏的开发管理提供了一定的借鉴意义。based on the reservoir geologic study, by application of combining theory with practice, empirical method, and analogic method, technical policies of development are researched, such as the formation pressure maintenance level, the flowing pressure, intensity of water injection, intensity of fluid recovery （m3/d·m）, erc, of the oil deposit are studied in this article, in the light of the geologic and development characteristics of high water saturation, low pressure, low-permeability Triassic oil reservoirs in Suiting oilfield, such as poor physical properties, strong anisotropism, poor oil-water separation, low initial formation pressure, low saturated pressure, inadequate natural energy, high water-cut after oil well put into production, and low output, etc. Huaziping block is adjusted by using these policies, and good results are obtained. Simultaneously it provides certain reference for development management of this kind of oil deposit.
