The research for metallogenic evolution mechanism in the region indicates that gold ore formation has undergone three stages : gold elementary source bed formation stage from the neo - archean to the paleo - proterozoic and meso - proterozoic, regional metamorphism - migmatization gold reenrichment stage at the late meso - proterozoic, structure - fluid - gold mineralization stage at the yanshan period
對礦帶成礦演化機理的研究表明,金礦形成經歷了3個階段:新太古至古、中元古代金初始礦源層形成階段;中元古代末期區域變質混合巖化金再富集階段和燕山期構造流體金成礦作用階段。From the dongying formation ( ed ) to neogene, the shahejie formation was located in the late diagenetic stage a1 ~ a2 ; the oil and gas pools formed in a wide scale. at present the lower e2s3, with overmatured source rocks and low porosity reservoir rocks, gets into the late diagenetic stage b - c in the northern qibei sag where is not favorable for petroleum accumulation, but the others of the shahejie formation are locate still in the late diagenetic stage a1 - a2 and propitious to form oil and gas pools based on the diagenetic numerical modeling under the condition of overpressure, we build a multiple unit cubic equation model for porosity prediction, as the result of the application of qibei sag, the prediction error is less than 2 %, and the precision excess that of foreign same model
歧北凹陷的模擬結果表明,在沙河街組沉積末沙河街組三段就進入晚成巖階段a _ 1期,油氣藏開始形成;在東營組沉積時期晚第三紀,沙河街組大部分地層處于晚成巖階段a _ 1 a _ 2期,生、儲、蓋層發育,是其主要成藏期;現今在歧北凹陷北部沙三段下部進入晚成巖階段b c期,儲層物性較差、不利於成藏,其他層段仍處于晚成巖階段a _ 1 a _ 2期,有利於油氣藏的形成。The pattern of diagenetic and porosity evolution are established. the primary porosity of the reservoir rocks was 35 %, which was reduced by 21. 7 % by compaction and pressure solution and 8. 2 % by cementation. the secondary pores were produced by organic acids " dissolution during organic matter maturing stage, resulting an increase of porosity by 5 %
預測本區砂巖原始孔隙度為35 ,經機械壓實和化學壓溶作用孔隙度損失了21 . 7 ,后經自生礦物的膠結作用,孔隙度損失了8 . 2 ,當進入有機質成熟階段,有機酸的溶解作用產生次生孔隙,使孔隙度增加5 ,現今保存的平均孔隙度為10 . 1 。
