基尔库克油田位于伊拉克北部,1927年发现。1934年开始采油。面积300平方公里,工业储量21亿吨。1974年时油田共有50口油井。日产油水平为12万吨,平均单井日产2400吨,油层为第三纪石灰岩。为了保持油藏压力及产油量,1961年开始注水、1970年12月的日产油量为146000吨,至1970年12月累积产油6.9亿吨,其中4.32亿吨是注水后采出的。注水后油藏压力提高了6.3大气压,产油量也提高了。一、地质构造和油层性质基尔库克油田为一狭长背斜构造,构造走向东南—西北,总长约98公里,宽约4公里
Kirkuk oil field is located in northern Iraq, discovered in 1927. 1934 began production. Area of 300 square kilometers, industrial reserves of 2.1 billion tons. In 1974, there were 50 oil wells in the field. Nissan oil level of 120,000 tons, the average single well Nissan 2,400 tons, the Tertiary limestone reservoir. In order to maintain reservoir pressure and oil production, water injection started in 1961, with a daily oil production of 146,000 tons in December 1970 and a cumulative production of 690 million tons in December 1970, of which 432 million tons were recovered after waterflooding. Reservoir pressure increased by 6.3 atm after injection and oil production also increased. First, the geological structure and reservoir properties Kirkuk oilfield is a narrow anticline structure, structure to the southeast - northwest, with a total length of about 98 km and a width of 4 km
