华北油田隐蔽油气藏勘探在取得了重要成果的同时,还摸索出了配套的勘探思路、工作方法、技术系列和研究工作的组织形式。华北油田经过了四十多年的油气勘探开发历程。20世纪80年代至90年代初,伴随着古潜山油田勘探进入尾声,原油产量第一次大幅度下降。1998年以来由于第三系构造油气藏勘探程度较高,难度加大,油田再度出现了稳产的困难。 Concealed oil and gas reservoir exploration in Huabei Oilfield has made important achievements while exploring the supporting exploration ideas, working methods, technical series and organizational forms of research work. Huabei oil field after more than 40 years of oil and gas exploration and development process. From the 1980s to the early 1990s, with the exploration of ancient buried hill oil fields, the output of crude oil dropped drastically for the first time. Since 1998, due to the higher degree of exploration of the Tertiary structural oil and gas reservoirs and the more difficult it is, the oilfields once again experienced difficulties in maintaining stable production.
