尕斯库勒油田E32油藏白云岩成因及储集性

通过分析尕斯库勒油田E3^2油藏白云储集层的空间分布、岩石学特征、沉积环境、形成机制和储集性，认为本区白云岩储集层为准同生成因，主要形成于滨湖、浅湖和半深湖环境，滨湖区主要由毛细管作用形成，浅湖或半深湖区则主要由回流渗透作用形成。其储集空间包括基质孔隙和裂缝孔隙两部分，为双孔隙介质，是良好的油气储集层。油田勘探实践已经证实了这类储集层的重要性。

Origin and reservoir performance of dolomite of E32 reservoir, Gasikule, Qinghai Oilfield

The space distribution, petrologic features, sediment environment, formation mechanism and storage ability of the lacustrine dolomites in E3^2 reservoir, Gasikule, Qinghai Oilfield, show that dolomite reservoir is of pene-contemporaneous origin, which is mainly formed under shore lake, shallow lake and half deep lake condition. The shore lake section is mainly formed by capillary process, shallow lake and half deep lake sections are formed by refluence osmosis process. The reservoir is of double porosity with matrix pores and fractures as storage spaces, and better oil and gas reservoirs have been proved by petroleum plays.
