摘要： 针对底水火山岩油藏基质渗透率低、裂缝发育、见水快和产量低的特点,运用油藏数值模拟方法,采用双孔双渗、油气水三相模型,以新疆准噶尔盆地金龙油田J10井区为研究对象,开展水平井长度、井距、避水高度、裂缝间距、裂缝半长和裂缝导流能力对水平井产量的影响研究,得到了水平井开发参数最优方案。结果表明:J10井区水平井开发合理井距为300～350 m,水平段长度为630 m,最优避水高度为225 m,裂缝间距为90 m,裂缝半长为105 m,裂缝导流能力为60 D·cm。该研究结果在现场应用中获得了较好的生产效果,可为底水火山岩油藏开发部署提供参考。

Abstract: In view of the characteristics of low matrix permeability, fracture development, fast water occurrence and low production of volcanic reservoirs with bottom water, the reservoir numerical simulation and the oil-gas-water model with dual porosity and dual permeability were adopted to study the influences of horizontal well length, well spacing, water avoidance height, fracture spacing, fracture half-length and fracture conductivity on horizontal well production in the study case of Well Block J10 in Jinlong Oilfield, Junggar Basin, Xinjiang. The optimal solution for horizontal well development parameters was worked out, that is, the reasonable horizontal well spacing in Well Block J10 was 300 to 350 m, the length of horizontal section 630 m, the optimal water avoidance height 225 m, the fracture spacing 90 m, the fracture half-length 105 m, and the fracture conductivity 60 D·cm. The results of this study have been applied in the field with good production results, and can provide a reference for the development deployment of volcanic hydrocarbon reservoir with bottom water.
