摘要:
白豹油田白111区块为一典型的边底水岩性构造油藏，进入中高含水期后地层压力保持水平低、水驱效果差、采液强度和注水强度偏低，需对注采结构进行调整。针对白111区块砂体分散、储层单一、各井区为独立油水系统的地质特点，通过油藏工程、动态分析等方法对油藏合理井底流动压力、合理采液强度、合理注水强度以及合理注采井数比等开发技术指标进行研究和论证，确定了油藏目前开采状况下最优的开发技术政策界限，并结合油水井相关生产动态信息提出开发调整方案来指导油藏高效开发。结果表明，当井底流动压力在4～6 MPa之间、采液强度为05 m3/（d〖DK〗·m）、注水强度为26 m3/（d〖DK〗·m）、注采井数比为
1〖DK〗∶25时，油藏开发效果较好。方案调整后，对区块未来10年的开发指标进行预测。结果显示，10年后的年产油量和采油速度与方案调整之前相比均有所提高，预计含水上升率由83%下降到14%，采出程度由151%提高到165%，油田在中高含水期阶段达到提液增油的目的。该预测方法为侏罗系油藏开发的持续稳产提供了有效途径，也为其它此类边底水中低渗透油藏的高效开发提供了理论依据。
Abstract:
 The block Bai111 in Baibao Oilfield is considered as a typical lithologicstructural reservoir with edgebottom aquifer. The development in middle and high watercut stages are characterized by low formation pressure maintenance level, poor waterflooding performance, relatively low liquid production and water injection intensities. It is of great necessity to adjust the injectionproduction system. In view of disperse sandbody distribution, singular reservoir development and independent oilwater system in each wellblock in the Block Bai111, oil reservoir engineering and production analysis were adopted to study and demonstrate the reasonable bottomhole flowing pressure, liquid production intensity, water injection intensity and injectionproduction well number ratio. Result indicates that a better development performance can be gained when the bottomhole flowing pressure is maintained in 4-6 MPa, the liquid production intensity is 05 m3/(d·m), the water injection intensity is 26 m3/(d·m) and the injectionproduction well number ratio is 1〖DK〗∶25. The block development indicators for the next 10 years were forecasted after the development program adjustment. Both the cumulative oil production and oil recovery rate after 10 years after development program adjustment are improved comparing with that before development program adjustment and the watercut increasing rate is effectively controlled. This case could provide certain references for the efficient development of lowmedium permeability oil reservoir with edgebottom aquifer.
