摘要
混合井网的合理井网密度研究对油区的持续稳定发展起着举足轻重的作用。在对目前合理井网研究方法分析的基础上,应用最优化和经济学理论,建立了以经济效益为中心、适合混合井网特点的合理井网密度确定模型——改进的多目标优化模型。为验证该模型的可行性和正确性,将其应用于某油区典型调整单元,测算取得了令人满意的效果。该模型的建立对于油田今后的老区调整和油田开发规划的编制具有重要的现实意义。
Horizontal wells are increasingly applied in oilfield development in conjunction with vertical wells.The study of well spacing density of combined pattern is of crucial importance to sustainable development of an oilfield.Based on analysis of rational pattern study method,a well spacing density model focusing on economic benefit—— modified multiple objective model,has been established for combined pattern by using optimization and economic theory.The model has been applied to a typical adjustment oil unit to verify its feasibility and accuracy and has achieved satisfactory result.This model is of practical significance to old oilfield adjustment and preparation of development program.
