ONH油田主要开发层系因注采井网不完善、注采不平衡、地层压力保持难度大,因此,采出程度低,剩余油富集丰富。在此情况下对油田的开发特征开展了分析工作,利用分析成果指导下步新井井位部署以及老井增产措施。经研究发现,ONH油田仍然具有上产的潜力,特别是合理利用油田开采不平衡造成的诸多方面的差异,开展结构调整和井网加密;研究和发展新的开采工艺,提高老井采收率。利用最新测井技术复查老井油气层,挖掘油田内部油气资源,获得了增储上产的显著效果。
Due to the imperfect well pattern of injection and production well, unbalanced injection and production, formation pressure of the ONH field is difficult to maintain. Therefore, the recovery level is low and the remaining oil is rich in enrichment. In this case, the development characteristics of the oilfield are analyzed, and the results of the analysis are used to guide the deployment of new wells in the next step and the stimulation measures for the old wells. The study found that the ONH oilfield still has the potential to go to production, especially in the rational use of oil field imbalance caused by many aspects of differences, to carry out structural adjustment and well patterning; research and development of new mining technology to improve the recovery of old wells . Using the latest logging technology to review the Laojing oil and gas reservoir and tap the oil and gas resources within the oilfield, the remarkable effect of increasing reserves and increasing production was obtained.
