摘要(Abstract):
1990年发现中国第一个古生代海相特大油田——塔河油田后,油气勘探开发取得了重大进展,到2011年累计探明油气储量达12×10~8 t油当量,但是由于碳酸盐岩缝洞型储集体十分复杂,纵横向变化大,给开发工作增加了很大难度。在近年研究成果和勘探开发资料的基础上,进一步研究了塔河油田奥陶系沉积微相、碳酸盐岩储集体特征,包括沉积特征、古岩溶储集体类型、缝洞充填特征等,并提出了油气勘探开发有利区的研究方向。
Since the discovery of the first Chinese Paleozoic marine giant oilfield-Tahe Oilfield in 1990,the significant progress has been made in the oil & gas exploration and development of the oilfield.By 2011,the cumulative proven petroleum reserves have researched 1.2 billion tons of oil equivalent.But due to the serious complexity of the fractured-cave carbonate reservoirs and rather bigger vertical and horizontal changes,the development difficult deteriorates a great deal.On the bases of the researches in the recent-year exploration and development data,the characteristics of the Ordovician sedimentary microfacieses and carbonate reservoirs,including the sedimentary characteristics,palaeokarst reservoir types,infilled features of the fractures and caves etc.are further figured out,and moreover the research directions for the plays of the oil and gas exploration and development are presented in the end.
