| 摘 要： | 由于储集层岩石结构和孔隙结构的特殊性，使得其在开发上不同于一般碎屑岩油藏，特别是砾岩储集层的普遍严重非均质性，给油田(藏)开发带来极大的难度．在系统总结国内外主要砾岩油藏基本特征和开发历程的基础上，对克拉玛依砾岩油藏开发效益进行了评估．指出克拉玛依砾岩油藏在开发中所应用的技术并不比国外差，但经济效益与国外同类油藏相比明显偏低，这主要与克拉玛依砾岩油藏的油层厚度小、储量少、原油粘度高、天然驱动能量低和由其决定的单井产量低等因素造成．

| Abstract: | The conglomerate reservoirs refer to the reservoirs with conglomerate as the main reservoir and producing pay. Due to the peculiarity of the rock structure and pore structure of the reservoir , they are different in development from the ordinary clastic reservoirs--- sandstone reservoirs, especially when the conglomerate reservoirs are generally largely heterogeneous, which brings great difficulty to field (reservoir) development. The number of conglomerate oil and gas fields is no big enough to achieve adequate data to make comparison between the conglomerate reservoirs in Karamay and those abroad. Several examples of conglomerate reservoirs and fields have been provided for comparison, the result of which is used to evaluate the development efficiency of Karamay conglomerate reservoirs on the basis of systematic summarization on the basic characteristics and development history of the conglomerate reservoirs of the examples. It is inferred through evaluation that the conglomerate reservoirs is generally characterized by severe heterogeneity , complex pore structure and that the sedimentary facies belt and tectonic movement are the primary factors controlling the oil-field production. It is pointed out that the technologies applied in the development of the conglomerate reservoirs in Karamay are no less advanced than those applied abroad, however the economics is significantly lower than the similar reservoirs abroad, and this is associated with such factors as small thickness, low reserve abundance, high crude viscosity, low natural drive and thus the resulting single-well production rate, etc. That is why we should learn the advanced technologies from home and abroad to enhance the economic of the conglomerate reservoir development in Karamay. |
