【摘要】：淺灘儲(chǔ)層不同部位的儲(chǔ)集物性差異明顯。對(duì)哈薩克斯坦扎納諾爾油田石炭系淺灘儲(chǔ)層的研究表明,沉積相是導(dǎo)致該類(lèi)儲(chǔ)層物性差異的主要原因。濱岸環(huán)境包括4個(gè)波浪帶,表現(xiàn)出不同的水動(dòng)力特征:1漲浪帶,海底低于正常浪基面,波浪對(duì)海底沒(méi)有明顯作用;2升浪帶,海底高于正常浪基面,同時(shí)水深超過(guò)2倍波高,海底沉積物受到輕微擾動(dòng);3破浪帶,水深介于1倍和2倍波高,海底沉積物受到持續(xù)擾動(dòng);4涌浪-沖浪帶,水深小于1倍波高,波浪破碎,海底沉積物劇烈震蕩。波浪帶控制了沉積物特征,據(jù)此將淺灘分為3個(gè)亞相:1間歇高能灘,主要沉積灰泥顆粒石灰?guī)r,儲(chǔ)集物性差,電測(cè)曲線表現(xiàn)出低聲波、高電阻和高伽馬特征;2破浪-升浪灘,主要沉積亮晶有孔蟲(chóng)-蜓石灰?guī)r,儲(chǔ)集物性好,電測(cè)曲線表現(xiàn)出高聲波、低電阻和低伽馬特征;3涌浪-沖浪灘,主要沉積亮晶鮞粒石灰?guī)r,儲(chǔ)集物性差,電測(cè)曲線表現(xiàn)出低聲波、高電阻和低伽馬特征。由海向陸方向,隨著水深逐漸減小、水體循環(huán)減慢以及鹽度增加,膠結(jié)作用的速度和強(qiáng)度出現(xiàn)顯著差異,導(dǎo)致不同亞相沉積物的原始孔隙及次生孔隙的發(fā)育明顯不同。因此,沉積相是控制該區(qū)儲(chǔ)層質(zhì)量的主要因素。
[Abstract]:The reservoir physical properties of different parts of shoal reservoir are obviously different.The study of Carboniferous shoal reservoir in Zananor Oilfield of Kazakhstan shows that sedimentary facies are the main reason for the difference of physical properties of this kind of reservoir.The coastal environment consists of four wave zones, showing different hydrodynamic characteristics: 1 rising wave zone, which is below the normal wave base, and the wave has no obvious effect on the bottom of the sea, which is above the normal wave base, and the water depth is more than 2 times higher than that of the normal wave base.The wave zone controls the characteristics of the sediments, according to which the shoals are divided into three sub-facies: 1 intermittent high energy beaches, the main sedimentary plaster grained limestone, poor reservoir physical properties, the electrical measurement curve shows a low voice wave, high electrical resistance and high gamma characteristics / 2 break-wave-Shenglang beach.The main sedimentary bright crystal foraminifera-fly limestone has good reservoir properties. The electric measurement curves show high sound wave, low electrical resistance and low gamma content. The main deposits are bright grain oolitic limestone, and the reservoir properties are poor, the characteristics of which are high sound wave, low resistivity and low gamma content.The electrical measurement curve shows the characteristics of low wave, high resistance and low gamma.In the direction of sea to land, with the decrease of water depth, the circulation of water body slows down and the salinity increases, and the rate and intensity of cementation show significant difference, which leads to the obvious difference in the development of primary and secondary pores in different subfacies sediments.Therefore, sedimentary facies are the main factors controlling reservoir quality in this area.
