【摘要】：在英買35井區(qū)志留系柯坪塔格組上段,針對致密海相石英砂巖儲層的成因,結(jié)合薄片、包裹體測溫、伊利石測年、陰極發(fā)光等資料,認為石英砂巖存在4期主要的石英增生:1泥盆紀、石炭紀,來源于寒武系硅質(zhì)生物遺骸中的硅質(zhì)增生;2二疊紀火山噴發(fā),來源于寒武系、奧陶系、志留系的硅質(zhì)大量增生;3三疊紀、侏羅紀地層暴露剝蝕,來源于二疊系凝灰?guī)r的硅質(zhì)增生;4白堊紀至今地層快速沉降深埋,志留系成巖活動加劇,硅質(zhì)析出增生。二疊系火成巖噴發(fā)提供了石英增生的動力與物源。毗鄰二疊系火成巖侵入體的志留系砂巖儲層存在熱接觸變質(zhì)帶和致密膠結(jié)帶。
[Abstract]:In Yingmai 35 well area of upper Silurian KEPINGTAGE formation, causes for marine dense quartz sandstone reservoir with thin inclusions, illite dating, cathodoluminescene, that there are 4 main quartz sandstone quartz overgrowths: 1 Devonian, Carboniferous, derived from Cambrian siliceous organisms remains in siliceous hyperplasia; 2 Permian volcano eruption, originated in the Cambrian, Ordovician, Silurian and siliceous proliferation; 3 Triassic, Jurassic strata exposed to erosion, originated from Permian siliceous tuff of the Cretaceous formation has 4 hyperplasia; rapid settlement of deep buried, Silurian diagenetic activity intensified, siliceous precipitation proliferation. Permian igneous rock eruption provides quartz overgrowth the power and source. The thermal contact metamorphic zone and dense cementation of sandstone reservoirs in Silurian to Permian igneous rocks.
