人们居住在楼房的各个套间里,又出入于套间的各条过道中,这种再简单不过的日常生活,却给石油与天然气的储集和流动作了一个颇为相仿的比喻。据统计,世界上7口日产万吨的油井,都出自碳酸盐岩地层;日产千吨的油井和百万立方米的气井,在碳酸盐岩地层中更是屡见不鲜。我国华北任丘油田、西北塔里木沙参2井、西南四川的71个气田和湖北的建南气矿等等,都是属于碳酸盐岩类型的油气田。它们的共同特点是靠孔、洞储集,靠缝隙渗滤。油气“居住”的空间和活动的空地,犹如人们的卧室和走道一样。别看道理如此简单,石油地质人员却苦苦摸索了许多许多年。因为先前石油人员把不均匀的裂缝性碳酸盐岩油气藏和均匀的孔隙性碎屑岩油气藏视为同等,于是在布井勘探和布井开发时采用了“梅
People living in the various suites of buildings and out of the aisle of the suites make this simpler daily life a rather analogous metaphor for the accumulation and flow of oil and gas. According to statistics, the world’s seven Nissan million tons of oil wells, are from the carbonate rock formation; Nissan 1,000 tons of oil wells and one million cubic meters of gas wells in the carbonate formation is more common. Renqiu Oilfield in North China, Northwest Tarim Arsenal 2 wells, 71 gas fields in Southwest Sichuan and Jiannan gas in Hubei and so on, all belong to the carbonate rock type oil and gas fields. Their common feature is by hole, hole reservoir, percolation by the gap. Oil and gas ”living “ space and activities of the open space, like people’s bedroom and walkway the same. Do not look so simple reason, the oil geology staff has worked hard for many, many years. Because previous oil officers viewed unevenly fractured carbonate reservoirs and even porous clastic reservoirs as equal, they used ”plum
