南海珠江口盆地油气勘探始于1973年,经历了区域概查、对外合作地球物理勘探和对外合作勘探开发三个阶段。1979年8月11日珠5井首次在下第三系中喷出工业油流,之后相继发现了一批高产井和油气藏。如国内砂岩产层测试最高的井:惠州21—1—1井折算日产油达4200多立方米;国内大型(储量达2亿吨)礁灰岩油田流花11—1油田,已于1996年5月投入开发。目前在东经113°10’以东的珠江口盆地区内(南
Oil and gas exploration in the Pearl River Mouth Basin in the South China Sea began in 1973, undergoing three phases of regional survey, cooperation with foreign countries in geophysical exploration and foreign cooperation in exploration and development. On August 11, 1979, Well Zhu 5 first jetted industrial oil flow in the Lower Tertiary. Later, a number of high-yield wells and reservoirs were discovered. For example, the highest well in the sandstones test in China is Huizhou 21-1-1 well, which translates to more than 4,200 cubic meters of daily output of oil. The large-scale domestic Liuhua 11-1 oilfield, with a reserve of 200 million tons, was established in 1996 Month into development. At present, within the Pearl River Mouth Basin east of 113 ° 10’E (south
