塔里木盆地柯坪冲断带储层研究
|
摘要
塔里木盆地寒武系碳酸盐岩发育有肖尔布拉克组、吾松格尔组、沙依里克组,以及阿瓦塔格组等大规模优质白云岩储层,油气勘探前景广阔。但白云岩储层的形成及控制因素比较复杂,且与灰岩形成的控制因素有明显差异,至今仍然没有得到足够的认识。本文针对塔里木盆地柯坪冲断带寒武系白云岩储层,通过大量的野外、岩石薄片观察,发现各种储集空间发育,有晶间孔、晶间溶蚀孔及溶蚀孔洞、溶蚀缝、裂缝、缝合线,溶蚀作用、热液作用、重结晶作用、去白云岩化作用和构造作用等一系列基础研究分析,系统的归纳出了该区域白云岩储层发育的影响因素,以及在巨厚碳酸盐岩地层段中给出了有利的白云岩储层发育的层段。以期为今后的研究提供可靠的资料。
Cambrian carbonate rocks of Tarim Basin have some large-scale high-quality of dolomite reservoir,such as Xiaoerbulake Formation,Wusonggeer Formation,Shayikelike Formation and Awatage Formation,and oil and gas exploration prospects.But the formation and control factors of the dolomite reservoir are more complex,and the control factors formation of limestone is significant difference and still not get adequately recognized.This article aimed at Cambrian dolomite reservoir of Kelpin thrust belt of Tarim Basin.Through a lot of wild,rock Microscopical observation,finding a variety of reservoir space development,such as intergranular pore,intergranular erosion hole and erosion hole,corroded fissure,cracks,sutures,dissolution,hydro thermal,recrystallization,dolomitization and configured to effect a series of basic research and analysis.The factors affecting is systematically inducted the dolomite reservoir development of the region,and gives a favorable intervals dolomite reservoir development in thick sections of carbonate rocks in order to provide reliable information for future research.
