摘要
鄂尔多斯盆地低渗透油藏物性差,产能低,储层有裂缝。在开发过程中,由于未处理好裂缝方位与注采连线之间的关系、断层导水以及低渗油藏底水锥进问题,导致部分油井暴性水淹。通过对相关文献资料的调研,本文提出了解决油井暴性水淹的措施及步骤,以期达到稳油控水,提高采收率的目的,从而保证油藏开发的整体经济效益。
The low permeability reservoirs in Ordos Basin have some characteristics,such as poor physical properties,low productivity,and fractures in reservoirs,etc.In the development,because of some problems,such as the relationship between fracture orientation and injection-production connection,water-guiding fault,bottom water coning in the low permeability reservoirs,etc.,some oil wells arouse sudden water influx.Through searching related information,this paper proposed some measures to solve sudden water influx.Thus,enhancing oil recovery guarantees the entire economic benefit in the reservoir development.
