龙虎庄油田,位于冀中坳陷,牛驼镇凸起东南部二台阶上,是霸县潜山带东部一个奥陶系古潜山油藏。1977年4月发现油田,接着就边勘探、边生产、边建设,并于当年9月进行了人工注水,保持地层压力开采,当年生产原油44.4万吨,采油速度4.3%。1978年采用老井放大生产压差和补充生产井的办法实现了高速开采,年底生产井数达到9口,日产水平提高到最高峰2900吨以上。前两年即采出了可采储量的51.5%,第三年又采出了可采储量的26.5%,达到了78%,接着产量迅速下降,到1985年底,生产井8口,日产量为100—150吨,综合含水为54.4%。生产八年,已累积采出可采储量的93.8%,油田进入开发后期、低速稳 Longhuzhuang Oilfield, located in the Jizhong depression, Niu Tuo town protruding southeast of the two steps, is the Baxian buried hill east of an Ordovician buried hill reservoir. In April 1977, the oilfield was discovered and then explored side-by-side while it was being built. In September of that year, artificial flooding was carried out to maintain the strata pressure exploitation. In the same year, 444,000 tons of crude oil were produced and the oil recovery rate was 4.3%. In 1978, the old wells were used to enlarge the production pressure and replenish the production wells to realize high-speed mining. By the end of the year, the number of production wells reached 9 and the daily production level increased to the peak of 2,900 tons. In the first two years, 51.5% of the recoverable reserves were recovered. In the third year, recoverable reserves of 26.5% were recovered to 78%. Then the output decreased rapidly. By the end of 1985, the production wells had 8 and the daily output was 100-150 tons, 54.4% of the combined water. Production for eight years, has reclaimed 93.8% of recoverable reserves, the oilfield into the late development, low-speed stability
