双河油田Ⅷ-Ⅸ油组合理井网密度优选

Optimization of appropriate well spacing density in Ⅶ-Ⅸ reservoirs of Shuanghe oilfield

运用多种方法对双河油田Ⅷ-Ⅸ油组的合理井网密度进行了计算,然后在此基础上,部署了五套井网密度方案,应用三维数值模拟模型对各套方案的开发指标模拟计算、经济指标对比分析,最终优选出开发指标及经济指标均较好的方案,最后,综合考虑各计算方法的优势及局限性,确定了双河油田Ⅷ-Ⅸ油组的合理井网密度。

By using different methods,the calculation on well spacing density in Ⅶ-Ⅸ reservoirs of Shuanghe oilfield has been carried out and on the basis of this calculation,5 proposals on well spacing density have been deployed.The best proposal with good development and economic indicators has been finally optimized through mathematic simulation and comparative analysis among all these indicators.In the end,taking all advantages and limitations of all kinds of cal culation procedures into consideration,the appropriate well spacing density has been confirmed,providing technical sup-port for the design of field development plan.
