Abstract: In face of low oil prices, the crude oil production enterprise adopts a cost-effective management in the areas of newwell productivity construction, production and development, conversion of development pattern, and withdrawal from the full development cycle. It bases itself on evaluation of single-well performance, reduction of production cost as the means, and fulfillment of the high-performance development objective. The model for optimization of investment is established at the stage of new-well productivity construction to optimize investment structure and keep design of new well in connection with economic performance. At the production and development stage, the plate of “three costs and four performance zones” for risks pre-evaluation of stimulation measures is created to tighten control at the sources, avoid inefficient investment measures and control budget of high-cost well. As for conversion of development pattern, the design plan is optimized for management of production details and guarantee of high performance in operation of key projects. Based on cost-effective control over the full development cycle, the enterprise promotes its sustainable development at high quality and in high economic performance.

摘要： 面对低油价，原油开采企业实施从新井产能建设、生产开发、方式转换直至退出开发的全生命周期的降 本增效管理，以单井效益评价为支撑，以降低生产成本为手段，实现提高开发效益的目的。在新井产能建设阶段，建 立投资优化模型，优化投资结构，保证新井设计与实施效益起步；在生产开发阶段，创建“三线四区”增产措施风险 预评价模板，从源头控制，避免无效措施投入，实现高成本井预控管理；在开发方式转换阶段，优化方案设计，精细 生产管理，保证重大项目效益运行。通过实施全生命周期降本增效管理，推动企业有质量有效益可持续发展。
