摘要:

白家海—五彩湾地区苍房沟群的储层岩石类型多样,但以裂缝—孔隙型储集层为主。成岩作用类型多而复杂,苍房沟群处于晚成岩时期,其岩性、沉积相以及成岩作用对储层物性具有不同程度的影响。在研究区将苍房沟群划分出6种储集砂体类型,分别为冲积扇—辫状河砂砾岩体、水下冲积扇砂砾岩、扇三角洲砂砾岩体、湖底扇砂砾岩、滨浅湖滩坝砂体、曲流河河道砂体。通过对储集砂体的详细分析,建立了储集砂体的评价标准,认为扇三角洲砂体和湖底扇砂体是最有利的储集体,冲积扇—辫状河砂体以及水下冲积扇砂体是较有利的储集体。

Abstract:

The rock types are various in Cangfanggou Group of the Baijiahai-Wucaiwan area. The reservoir is of crack-pore type. The diagenetic types are various and complex, such as mechanical packing, cementation and so on, and the diagenetic stage is in late diagenetic epoch. The lithology, sedimentary facies and diagenesis have different influences on the reservoir properties Six sandbody types are identified in Cangfanggou Group, which are alluvial-fan-braided-river-glutinite-body, underwateralluvial-fan-glutinite, fan-delta-glutinite-body, sublacustrine-fan-glutinite, near-shllow-lake-beach-dam-body and meanderingriver-fluvial-channel-sand-body.The evaluation criterion about the reservoir is established by detailed analysis on the sandbodies.Sandbodies of Fan delta and sub-lacustrine fan are the most beneficial reservoirs. Sandbodies of alluvial fan and subfluvial alluvial fan are more beneficial reservoirs.
