摘要:
介绍了罗家地区泥页岩沉积环境与成藏特征。作为烃源岩和储集层的泥页岩是多种矿物组分的混合岩性体,其储集空间包括无机孔隙、有机孔隙和微裂缝,属于非常规特低渗透率致密储层。利用偶极子声波测井资料,结合常规测井和岩心分析资料,定性判断泥页岩储层主要矿物成分、划分岩相类型。分岩相类型建立了岩石矿物组分百分含量解释模型。研究表明,纵横波速度比可以指示泥页岩层理、孔隙发育带及含油性特征。在罗家地区的实际应用表明,该方法准确可靠,可为勘探决策提供参考依据。
Abstract:
Introduced are the sedimentary environment and accumulation characteristics of shale reservoirs in Luojia area. As the source rock and reservoir rock, the shale is a sort of lithosome with multimineral compositions, and its reservoir space includes inorganic, organic pores and microcrack, so it is an unconventional ultralow permeability and compact storage layer. Dipole acoustic logging data and conventional logging and core analysis data are used to discriminate essential mineral compositions qualitatively and classify the lithofacies. Established is the percentage composition interpretation model of formation mineral constituents according to the lithofacies types. The study shows that velocity ratio of Pwave and Swave can be used to indicate favourable shale laminated bedding, pore zone and good oilbearing characteristics of shale. Practical application in Luojia area indicates that this method is accurate and reliable, which can provide a reference basis for oil exploration decisionmaking.
