摘要
致密气是当今石油工业的一个新领域,据中国石油2012年估计,中国致密气总资源量约为16×10^(12)m^(3),是接替常规油气能源的重要力量,是实现中国能源革命的突破点。中国实现致密气规模化开发的时间较短,其中标志性事件是2006年苏里格气田5+1合作模式探索出的致密气高效开发道路。而致密气SEC储量评估方法研究尚处于不断积累和完善的阶段,尤其是与常规油气评估相比,概率法在非常规油气未开发储量的评估中具有较强的适用性。本文立足于鄂尔多斯盆地东缘临兴致密气的生产特点和开发规律,通过细分井型、开发阶段和递减规律,剖析影响产量递减规律的渗流机理,采用确定法和概率法相结合的方法对研究区展开SEC储量评估,该研究成果对于我国非常规致密气资源的SEC上市储量评估提供一定的参考和借鉴。
Tight gas is now a new field in the oil industry.According to the 2012 estimate of PetroChina,China's total tight gas resource is about 16×10^(12)m^(3),which is an important force to replace conventional oil and gas energy and a breakthrough point for China's energy revolution.It is relatively short for China to realize large-scale development of tight gas,among which the landmark event is the high-efficiency development road of tight gas explored by the 5+1 cooperation mode of Sulige gasfield in 2006.However,the study on tight gas SEC reserve assessment method is still in the stage of continuous accumulation and improvement.Especially compared with conventional oil and gas assessment,probability method has strong applicability in the assessment of unconventional oil and gas reserves.Based on in the east margin of Ordos Basin and tight gas production characteristics and development rule,through segmentation well type,development stage and the law of diminishing influence the production decline rule of seepage mechanism,adopt the method of determine method and probability method combined with the SEC reserves evaluation in study area,the results of the study for unconventional tight gas resources in China's listed SEC reserves evaluation provide certain reference and reference.
