长庆油田属于低渗透油田,采油主力开发层位于三叠系延长组,在纵向表现上为多套小层叠合,并受到注水影响,对于油井层间压差矛盾较为突出,而分层泵采油技术能够最大化消除油井层间干扰,特别是长庆油田地饱压差小,气油比高,结合现场试验以分采泵开采更具有适应性。 Changqing Oilfield belongs to the low permeability oilfield. The main oil recovery development zone is located in the Triassic Yanchang Formation, with multiple sets of small overlays superimposed on the longitudinal direction and affected by water flooding. This is particularly true for the pressure difference between oil layers, while stratified pumping Technology to maximize the elimination of interference between oil wells, especially in Changqing Oil Field pressure is small, high gas-oil ratio, combined with field tests to sub-mining more adaptive.
