摘要:

从煤层气成藏过程及其构造控制、沉积作用对储盖组合的影响、水文地质控制动态含气量、高产影响因素及控制机理5个方面,重点总结了沁水盆地煤层气富集高产地质理论新进展。研究认为:构造演化控制成藏过程、沉积及水文地质控制保存条件,进而影响煤层气富集;地层能量、渗透性及局部构造影响煤层气渗流,进而控制高产;富集与高产是煤层气勘探开发过程中的2个层次,高产分析是在富集区评价基础上开展的进一步评价。基于此,结合大量的生产实践数据分析,厘定富集、高产2个递进的评价目标、细化为4个层次共21个主控因素,采用层次分析、定量排序、模糊数学、数值模拟等方法,以沁水盆地为刻度区开展富集高产区评价,建立定量化评价指标体系,优选沁水盆地樊庄、潘庄、郑庄、马必,夏店,安泽,柿庄南7个富集有利区,以及在富集区内的潘庄、樊庄南、樊庄北、马必东,夏店南,郑庄南,安泽7个高产有利区。

Abstract:

The advancement in the geological theory in respect to the enrichment and high yield of CBM in Qinshui Basin has been emphatically highlighted in five aspects,namely CBM accumulation process,the structural controlling,the depositional impact on reservoir-cap assemblages,the dynamic gas content controlled by hydrological geology,high yield influencing factors and the controlling mechanism.It is concluded that through controlling of reservoir-forming process,depositional and hydrogeological controlling and preservation conditions,the tectonic evolution thereby influenced CBM enrichment;the formation energy,permeability and regional structures affected the seepage of CBM,and thereby the high yield of CBM;enrichment and high yield are the two levels for the exploration & development processes of CBM.The analysis of high yield is the further evaluation which is carried out under the basis of enrichment evaluation.Based on that,combined with massive field production data analysis,two gradual assessment goals,namely enrichment and high yield are confirmed,21 main controlling factors in 4 levels are refined,and a quantitative evaluating indicator system is established by carrying out enrichment high yield area evaluation taking Qinshui Basin as a calibrated region,with adoption of methods namely hierarchy analysis,quantitative sorting,fuzzing mathematics and numerical simulation.As a result,7 enrichment favorable zones in Qinshui Basin are optimized,namely Fanzhuang,Panzhuang,Zhengzhuang,Mabi,etc.Furthermore,7 high yield favorable zones are optimized,namely Panzhuang,Fanzhuang South,Fanzhuang North and Mabi East,etc.

Key words: CBM, Enrichment, High yield, Main controlling factor, Qinshui Basin
