摘要: 雁107厚层砾岩油藏的储层岩性以白云岩为主,在开发初期,立足于储集空间以孔隙为主的认识,按照一般砂砾岩油藏的开发模式制定了开发方案,在投入开发不到两年、采出程度不到5%的情况下,其产油量即从投产初期的150t/d左右下降至20t/d左右,综合含水高达80%。在没有岩芯资料和测井系列不适合于裂缝研究的条件下,从油藏开发中暴露的矛盾分析入手,借助井壁取芯、压力恢复测试等资料,重点讨论了储层岩性差别与储集类型的关系,以及储集类型的识别在雁107砾岩油藏开发中的重要意义。

Abstract: the reservoir lithology of Yan 107 thick conglomerate reservoir is dominated by dolostone. At the early stage of development, on the basis of the recognition of the pore spaces being pores, the development plan was schemed according to the development model of common sandstone and conglomerate reservoirs, but, after two years development and under the condition of less than 5% recovery, the productivity declined from 150 t/d at beginning down to 20 t/d, comprehensive water cut was as high as 80%. Under the condition of no core data and the logging series being not suitable for fracture study, started from analyzing the contradiction exposed in development, by means of wall coring , pressure buildup testing, the reservoir lithology difference and accumulation relations between the types, as well as the application of the indentification of accumulation types on the development of Yan 107 conglomerate reservoirs, are discussed in detail.

Key words: conglomerate reservoir, accumulation type, fracture, development character
