摘要:
水平井井间干扰现象已经在海上油田水平井开发过程中表现出来,对油田的正常生产造成一定的影响。通过建立边水油藏水平井双井模型,应用势的叠加原理,推导出势分布的表达式、水平井产量公式及见水时间公式。通过敏感性分析确定了影响水平井产量及见水时间的主要因素。结果表明,储层性质是影响边水油藏水平井产量的主要因素; 水平井距边水距离和水平井产量是影响边水油藏水平井见水时间的主要因素。利用渤海BZ油田A57H井和A58H井对模型进行了验证,基本符合实际生产。该方法对边水油藏水平井部署及产量预测有一定的指导意义。
Abstract:
The interwell interference of horizontal well has already shown up in offshore oilfields,which has a certain effect on normal oil production.By establishing the double horizontal well model for edge-water reservoir,the expression of potential distribution,the production formula,and the water breakthrough time formula are drawn according to the theory of potential superimposition.The major factors,influencing oil production and water breakthrough time,are determined by the sensitivity analysis.The results showed that the reservoir property is the major factor influencing the oil production; the distance between horizontal well and the edge-water,and the oil production are major factors influencing water breakthrough time.The wells in BZ Oilfield,namely A57H and A58H,have been predicted by this model,and the obtained results are generally accorded with the actual production data.This method has guiding significance for well placement and production prediction of horizontal wells in edge-water reservoirs.
