【摘要】：碳酸盐岩油气藏在全球范围内分布广泛,统计世界上236个大型油气田,96个为碳酸盐岩油气藏,约占40%,而且储量规模大、产量高的油气藏多为碳酸盐岩油气藏,其储量约占总储量的50%左右,产量约占总产量的65%,碳酸盐岩油藏中有30%以上为裂缝-溶洞型油藏,该类油藏的主要储集空间以构造变形产生的构造裂缝与岩溶作用形成的孔、洞、缝为主,其中大型洞穴是最主要的储集空间,裂缝既是主要的储集空间,也是主要的渗流通道。在我国,这类油藏也有着广泛的分布,自20世纪70年代以来,我国在胜利油田、华北油田和辽河油田相继发现和开发了三十多个碳酸盐岩潜山油藏,上个世纪九十年代末发现了塔河油田。我国海相碳酸盐岩油气资源量大于300×108t油当量,石油资源量约150×108t,主要分布在塔里木和华北地区,但探明率仅8%。其中缝洞型油藏占探明储量的2/3,是今后增储的主要领域。油藏裂缝与岩块间三相渗流机理的研究也越来越完善和深入,专家们在进一步研究上述机理的基础上也进行了许多基本概念的研究,如渗吸采收率、渗吸半衰期、渗吸速度、岩块采出程度与时间的关系等,这些在实验室中得到的机理大多得到了现场资料和经验的验证。国内方面,随着20世纪70年代以来对国内碳酸盐岩油藏的开发,经历了边实践、边认识、边开发、边调整的历程,在油田开发上做了大量的工作,积累了丰富的经验,特别是任丘油田迷雾山组油藏的开发水平已经进入国外同类油田开发的先进行列。
[Abstract]:Carbonate oil and gas reservoirs are widely distributed around the world, with 236 large oil and gas fields in the world and 96 carbonate reservoirs, accounting for about 40% of the oil and gas reservoirs, with large reserves and more carbonate reservoirs with high yields. The reserves account for about 50% of the total reserves, accounting for about 65% of the total production, and more than 30% of the carbonate reservoirs. For the fractured and cave type reservoir, the main reservoir space of this type of reservoir is mainly composed of structural fractures and karst formation, holes, holes and seams, among which large caves are the main reservoir space, and the cracks are both main reservoir spaces and main seepage passages. In China, these types of reservoirs also have extensive distribution from 20. Since the 70s of the century, more than 30 carbonate Qianshan reservoirs have been discovered and developed successively in Shengli Oilfield, North China and Liaohe oil fields, and Tahe oil field was discovered at the end of 90s of last century. The oil and gas resources of marine carbonate rocks in China are more than 300 x 108t oil equivalent, and the amount of stone oil resources is about 150 * 108t, mainly in Tarim and in Tarim. In North China, the exploration rate is only 8%. of which the fractured hole type reservoir accounts for the 2/3 of the proven reserves. It is the main area to increase the reservoir in the future. The study of the three phase seepage mechanism between the reservoir cracks and the rock block is becoming more and more perfect and deep. Most of the mechanisms obtained in the laboratory have been verified by field data and experience. At home, with the development of domestic carbonate reservoirs in China since 1970s, the process of border practice, edge development and edge adjustment has been developed in the field of oil field development. A lot of work has been done and rich experience has been accumulated. Especially, the development level of the haogshan reservoir in the Renqiu oilfield has already entered the advanced ranks of the foreign oil fields of the same kind.
