阿姆河右岸B气田碳酸盐岩储层主控因素
|
摘要
土库曼斯坦阿姆河右岸在中晚侏罗世经历了卡洛夫期缓坡型碳酸盐台(或碳酸盐缓坡)向牛津期镶边陆架型碳酸盐台地的沉积演化,发育两类碳酸盐台地沉积相带,形成了丰富多样的沉积微相及碳酸盐岩储层类型。层以阿姆河右岸中部B气田为例,结合盆地区域沉积背景,分析缓坡礁滩与缝洞型碳酸盐岩发育主控因素,明确了规模性储集体的发育类型及分布特征,为下一步阿姆河右岸碳酸盐岩气田的勘探开发奠定了坚实的地质基础。
The Right Bank of the Amu River in Turkmenistan underwent the sedimentary evolution from the Carlov gentle slope carbonate platform(or carbonate gentle slope)to the Oxford marginal shelf carbonate platform in the Middle and Late Jurassic,and developed two types of carbonate platform sedimentary facies belts,forming a variety of sedimentary microfacies and carbonate reservoir types.Taking B gas ?eld on the right bank of Amu River as an example,combining with the regional sedimentary background of the basin,this paper analyses the main controlling factors of the development of carbonate rocks of gentle slope reef-shoal and fracture-cave type,clari?es the development types and distribution characteristics of large-scale reservoirs,and lays a solid geological foundation for the exploration and development of carbonate gas ?eld on the right bank of Amu River in the next step.
