宝浪低渗透油藏由于受构造及成岩作用的影响,裂缝比较发育,但裂缝分布不均衡,裂缝主要分布在构造轴部、东南部和东北翼大断层附近。裂缝发育区油水井生产特征与不发育区不同,即:注水井吸水能力强,采油井生产能力旺盛,油井水窜严重,方向性比较明显。宝浪低渗透油藏裂缝在油田注水开发中的作用,有利方面是提高油层渗透性;不利方面是裂缝易引起水窜,增大开发难度。注水开发时,要充分发挥有利因素,避免不利因素的影响,提高开发效果。
Due to the influence of tectonic and diagenesis, Baolang low-permeability reservoirs developed relatively well, but the fractures are not evenly distributed. The fractures are mainly distributed in the tectonic axis, the southeast and the northeast wing near the fault. The production characteristics of oil and water wells in the fractured development areas are different from those in the non-developed areas, ie, the water injection wells have strong water absorption capacity, strong productive capacity of production wells, severe water channeling and directional directivity. The role of the fractures of Baolang low permeability reservoir in the development of oilfield waterflooding is to enhance the permeability of the oil layer. The disadvantage is that the fractures can easily lead to water channeling and increase the difficulty of development. Water injection development, we must give full play to favorable factors to avoid the adverse effects of factors to improve development effectiveness.
