摘　　要：针对南堡油田注水开发油藏特点以及开发现状,在提液可行的前提下,利用油藏工程以及数值模拟方法对提液时机、提液幅度、合理注采比进行了研究,认为南堡油田注水开发油藏在含水达到70%~80%时提液,且提液幅度2~3倍最佳,合理注采比1.0~1.1之间。矿场实践表明南堡油田注水开发油藏通过提液能有效提高油井产量,2020年共实施29井次,井口累增油1.0万t。In view of the characteristics and development status of the Nanpu Oilfield’s waterflooding development reservoirs,on the premise that Liquid extraction is feasible,reservoir engineering and numerical simulation methods are used to study the timing of liquid extraction,liquid extraction range and reasonable injection-production ratio of water flooding,It is believed that Nanpu Oilfield The water-flooding development reservoir should extract liquid when the water content reaches 70%-80%,and the extraction range is about 2.5-3.5 times the best,and the reasonable injection-production ratio is between 1.0-1.1.Field practice shows that water injection development reservoirs in Nanpu Oilfield can effectively increase oil well production through liquid extraction.In 2020,a total of 29 well-times of liquid extraction have been implemented,with a cumulative increase of 10,000 tons of oil at the wellhead.
