“六五”期间,油气田地面工程建设在保证原油生产的前提下,围绕节能降耗进行了一系列攻关研究和技术改造,取得了显著成绩。例如,在油气集输技术流程上,采用了“单管密闭,投球清蜡,两级布站,泡沫塑料保温”的密闭常温集油新工艺,使每输1t原油的耗气量从20～25m~8下降到8～10m~8,节气60％;河南油田实现了原油全密闭输送,使损耗率从开始的4％降到0.3％左右,创全国最高水平,接近世界先进水平;原油稳定和轻烃回收技术,也收到了明显的经济效益。为了减少损耗,全国大中型油田已建
During the period of the Sixth Five-Year Plan, a series of research and technological transformations on energy conservation and consumption reduction have been made on the groundwork of oil and gas fields under the premise of ensuring crude oil production and remarkable achievements have been made. For example, in the process of oil and gas gathering and transportation, a new process of oil-in-oil collection at room temperature with single-tube confinement, balling and waxing, two-stage cloth station and foam insulation was adopted to reduce the air consumption per 1t of crude oil from 20-25m ~ 8 to 8 ~ 10m ~ 8, solar term 60%; Henan Oilfield realized airtight transportation of crude oil, the loss rate from 4% to 0.3%, the highest level in the country, close to the world advanced level; crude oil stability and Light hydrocarbon recovery technology, has also received significant economic benefits. In order to reduce losses, large and medium-sized oil fields have been built nationwide
