|
摘要
论文以红连、胜北地区上侏罗统喀拉扎组和白垩系地层为研究层位,通过对钻井资料(包括岩芯资料、录井资料、测井资料等)进行综合研究,掌握了各种资料所反映的沉积学信息,并运用沉积学和测井地质学原理,揭示了研究区内沉积环境的格局与变迁,建立了可反映沉积体系基本特征的沉积相类型及相单元,指出有利相带并优选了勘探目标。
研究认为,工区主要为陆源沉积的碎屑岩,发育了冲积扇、扇三角洲、河流、辫状河三角洲、湖泊五大类沉积相。喀拉扎组(J_3k),胜北地区发育冲积扇沉积体系,连木沁地区发育辫状河三角洲沉积体系,红南地区发育扇三角洲沉积体系。三十里大墩组(K_1s),胜北地区仍然为冲积扇分布,连木沁地区广泛发育辫状河沉积体系,红南地区为曲流河沉积体系。胜金口组(K_1sh),出现了短暂的湖泊环境,到连木沁组(K_1l),工区以滨浅湖沉积为主,仅胜北地区的3号、4号构造带上发育了曲流河沉积。
研究区五大类沉积相中冲积扇的扇端、扇三角洲、河流、辫状河三角洲相砂岩发育,物性好,是良好的储集层。喀拉扎组(J_3k),连木沁地区,其砂体南部较北部发育,西部较东部发育,红南地区砂体较连木沁地区更为发育,但油气显示不如连木沁地带,胜北地区砂体北部优于南部,东部好于西部,油气显示主要集中在胜北3号、4号构造。三十里大墩组(K_1s),三个工区砂体发育,油气显示主要集中在红连工区,胜北未见油气显示,总体来看,砂体以红南地区为优,连木沁次之,胜北最差。连木沁组(K_1l),胜北地区胜北3号、4号构造发育的几套河流相边滩沉积砂体,油气显示极好。
根据工区沉积相分布及砂体展布情况对有利相带的分布作了预测,认为辫状河三角洲前缘带、河流相沉积的河道砂与点砂坝、冲积扇的漫流沉积带为油气聚集的有利地带。
Aimed at the study on the Kalaza Formation of Upper Jurassic and Cretaceous inHonglian-Shengbei region, the paper analyzed the drilling information including rockcores, mud-logging and well-logging etc. The framework and evolution of thedepositional environment in the study area have been revealed using depositional andwell-logging principles, the types and units of depositional system established, thefavorable facies zones and the exploration targets pointed out as well.
The study strata consist of the continental clastic rocks, and have fivedepositional systems including alluvial fan, fan delta, fluvial facies, braided fluvialdelta and lake facies. In Kalaza Formation (J_3k), the alluvial fan facies are developedin the Shengbei region, the braided fluvial delta developed in the Lianmuqin region,the fan delta facies developed in the Hongnan region. In Sanshilidadun Formation(K_1s), the alluvial fan depositional system developed in the Shengbei region, thebraided river depositional system developed in the Lianmuqin region, the meanderingriver depositional system developed in the Hongnan region. In ShengjinkouFormation (K_1sh), the ephemeral lake facies developed in the region, and the shorelake facies chiefly developed in Lianmuqin Formation (K_1l), besides the meanderingfacies developed at the No. 3 and 4 tectonic belts of Shengbei region.
Reservoir rocks are mainly developed in the end alluvial fan, fan delta, fluvialfacies and braided fluvial delta, which are high-quality reservoirs and widelydistributed. In J_3k, at the Lianmuqin region, southern sand bodies are better than thoseof the north, and the west part is better than the east part. Sand bodies of the Honglianregion are superior to that of the Lianmuqin region, but its indication of oil and gas isinferior to that of the Lianmuqin region. At the Shengbei region, sand bodies of thenorth are better than that of the south, and the east part is better than the west, and theindication of oil and gas is mainly concentrated at the No. 3 and 4 tectonic belts. InK1s, sand bodies developed in three sub-areas, but hydrocarbon shows mainly in theHonglian region, and rarely in the Shengbei region. As a whole, the best sand bodiesdeveloped in the Honglian region, and the second in Lianmuqin, and the third in
Shengbei. In K1l, point bar of fluvial facies developed at the No. 3 and 4 tectonic beltsof Shengbei region, which showing great indication of oil and gas.According the distribution of sedimentary facies and sand bodies, the authorpredicts the distribution of the favorable facies belts, and points out that delta frontsub-facies of braided river, channel sand and point bar of fluvial facies, sheet-flooddeposit belts of alluvial fan are the best sedimentary facies belts for oil & gasaccumulation.
