【摘要】：油气资源是石油工业赖以生存和发展的物质基础。作为重要的含油气盆地之一,松辽盆地在我国石油工业历史发展进程中占有十分重要的地位。松辽盆地是我国东北地区由大、小兴安岭、长白山环绕的一个大型沉积盆地。盆地跨越黑龙江、吉林、辽宁三省,面积约26万平方公里。20世纪上半叶,美国、日本的地质工作者都曾在这一带进行过石油调查和勘探,但没有发现石油。经过近50年的大规模石油勘探,松辽盆地北部先后在多套含油层系获得油气发现,特别是葡萄花油层,已探明石油地质储量达24亿吨,目前仍然是重要的勘探对象。葡萄花油层以三角洲前缘相带为主,属于中部含油气系统。分析近年勘探开发资料表明,葡萄花油层石油可探明资源量在35-40亿吨,剩余资源为11-16亿吨。葡萄花油层剩余油探明储量依然成增长趋势,葡萄花油层依然是各油田的主力开采层系。太东地区葡萄花油层属中、低渗透岩性油气藏,研究其岩石物理相及其分布对评价其岩石储集性能,进行油藏综合评价和开发方案部署有重要意义。
[Abstract]:Oil and gas resources are the material basis for the survival and development of petroleum industry. As one of the important petroliferous basins, Songliao Basin plays an important role in the development of petroleum industry in China. Songliao Basin is a large sedimentary basin surrounded by large, small Xinganling and Changbai Mountains in northeast China. The basin spans Heilongjiang, Jilin and Liaoning provinces and covers an area of about 260000 square kilometers. In the first half of the 20th century, geologists in the United States and Japan conducted oil surveys and exploration in this area, but no oil was found. After nearly 50 years of large-scale petroleum exploration, the northern part of Songliao Basin has been discovered oil and gas successively in several oil-bearing strata, especially the Putaohua reservoir, which has been proved to have a petroleum geological reserve of 2.4 billion tons, and is still an important exploration object at present. The Putaohua reservoir is dominated by delta front facies zone, which belongs to the oil and gas bearing system in the middle part. The analysis of the exploration and development data in recent years shows that the proven oil resources in the Putaohua reservoir are 35-4 billion tons and the remaining resources are 11-1.6 billion tons. The proven reserves of the remaining oil in the Putaohua reservoir are still increasing, and the Putaohua reservoir is still the main production system of the oil fields. Putaohua reservoir belongs to middle and low permeability lithologic reservoirs in Taidong area. The study of its petrophysical facies and its distribution is of great significance to evaluate its reservoir performance and to carry out comprehensive reservoir evaluation and development plan deployment.
