摘要
随着勘探领域扩展和勘探对象的转变,中国陆上石油在实现储量持续稳定增长的同时,新增储量主体由构造油藏转变为岩性地层油藏、由中高渗地层转变为低渗-特低渗地层,储量品位持续下降。"十三五"期间,中国陆上石油新增储量将以稳为主,储量劣质化趋势难以逆转。储量品位劣质化对上游业务发展带来重大影响,表现在:勘探评价方法和部署思路的重大调整;油藏开发理念和模式的重大转变;勘探开发阶段工艺技术的重要性凸显;勘探开发项目现金流发生显著变化。面对新形势,为保证中国陆上勘探规模效益发展,建议以提高劳动生产率、降低成本为核心,采取以下五项措施:实施勘探开发工程一体化;稳步推进项目负责制;充分发挥市场机制作用;优化勘探开发工作流程;强化勘探开发项目全生命周期效益评价。
Along with changes in exploration targets and an expanding exploration domain, China's onshore petroleum reserves have maintained steady growth. The main type of new reserves has also changed from structural-trap(more-liquid) reservoirs to stratigraphic(into a rock or sand layer) reservoirs, and from medium-to-high permeability to low permeability and ultralow permeability reservoirs, with individual reservoir storage capacities continuing to decline. During the thirteenth FiveYear Plan, new reserves should remain stable, while the deterioration trend in reserve quality will be hard to reverse. This trend will greatly influence petroleum exploration and development as follows: major adjustment will be made to exploration evaluation methods and to deployment thinking; significant change will be made to development concepts and methods; oilfield engineering technology will be given clear and obvious prominence; and notable change will occur in petroleum project cash flow. In this new situation and to sustain development in the scale and benef it of China's onshore exploration, China needs to raise labor productivity, cut cost to the bone and implement the following five measures: Do exploration and development project integration. Forge ahead in establishing a project-leader system. Give full play to the role of the market mechanism. Optimize exploration and development work fl ow. Sharpen the estimation of exploration and strengthen development projects' evaluation over their entire life-cycle.
