去年,我国南海珠江口盆地发现了海上笫一个大油田——流花11—1油田,也是我国最大的珊瑚藻礁、滩块状油田,日产源油330吨,控制储量达1亿吨以上。就油气的运移来说,是国内罕见的远距离侧向迁移的典型代表。空有一幢住宅流花11—1油田位于东沙隆起的西部,距香港二百多公里,圈闭面积达三百多平方公里,油层厚度大,30—70余米,已钻的4口井中,井井见油;储渗条件好,孔隙度11—22%,最高近于40%,渗透率39—458毫达西,最大4650毫达西。如此优越的储油构造和储渗条件,然而。在油气运移之前,却是空空如也的空院宅,因为在隆起上的第
Last year, China’s Pearl River Mouth Basin in the South China Sea discovered the first large oil field - Liuhua 11-1 oil field, and also China’s largest reef coral reef, beach block oilfields, producing 330 tons of oil, control reserves of 100 million tons and above. As far as hydrocarbon migration is concerned, it is a typical representative of long-range lateral migration in China. There is a residential empty Liuhua 11-1 oil field is located in the western part of the eastern Shalong uplift, more than 200 kilometers away from Hong Kong, the trapping area of over 300 square kilometers, the reservoir thickness, 30-70 meters, drilled four wells, well Well see oil; good reservoir conditions, porosity 11-22%, up to nearly 40%, permeability 39-458 millidarcy, the maximum 4650 millidarcy. Such a superior oil storage structure and storage and infiltration conditions, however. Before the oil and gas migration, but it is empty vacant homes, because in the uplift of the first
