桩西油区低渗透油藏由于其特殊的地质条件,开发难度大。近年来坚持以地质研究为基础,建立精细三维地质模型,定量描述剩余油分布,以小井距开发差异性评价为指导,制定不同井区开发技术对策,不断提高配套工艺技术水平,充分挖掘各类低渗油藏的潜力,实现了桩西低渗透油藏连续9年稳步开发。 Due to its special geological conditions, the low permeability reservoir in Xiqie area is difficult to develop. In recent years, based on geological research, we have established a detailed three-dimensional geological model to quantitatively describe the remaining oil distribution. With the guidance of the differential assessment of development of small wells and intervals, we have formulated technical countermeasures for different well areas and continuously improved the level of supporting technologies to fully tap various types The potential of low-permeability reservoirs has enabled the steady development of the low-permeability reservoir in West Pile for 9 consecutive years.
