截至目前,中石油华北油田已连续七年新增储量超亿吨,油气产量连年稳定增长,为油田科学发展提供了有力支撑。随着华北油田进入中后期深度开发,整装规模储量的难度与日俱增,而新区勘探条件复杂,油田勘探开发面临着资源丰度低、勘探目标小、圈闭发现难度大等严峻形势。由于开采速度过快、后备储量不足等原因,该油田“九五”以后进入“小数点”勘探阶段,储量增长日趋困难。
Up to now, PetroChina Huabei Oilfield has newly added over one hundred million tons of reserves for seven consecutive years and its oil and gas output has been steadily increasing over the years, providing a powerful support for the scientific development of the oilfield. With the deep development of Huabei Oilfield in the middle and late stages, the difficulty of assembling large-scale reserves is increasing day by day. However, the exploration conditions in the new area are complex. The exploration and development of oilfields are facing severe conditions such as low resource abundance, small exploration targets and difficult discovery of traps. Due to the mining speed is too fast, insufficient reserve reserves and other reasons, the oil field into the “decimal point ” exploration stage after the “95”, the reserves growth more and more difficult.
