基于趋势面理论的沙尔湖凹陷煤层气储量评估

Reserves Estimation of Coalbed Methane in Sha'erhu Sag Based on Trend Surface Theory

以新疆吐哈盆地为依托,通过运用趋势面分析理论的数学地质方法,结合相关的软件,对吐哈地区沙尔湖凹陷赋存的巨厚煤进行模拟。研究表明,该地区地质条件较为复杂,煤层厚度起伏较大,但煤炭资源可观,煤层气资源量丰富,具有相当好的开采前景。通过建立一整套适合该区域储量计算的流程,为后续的勘探开发提供了可行的依据。

Based on Turpan-Hami Basin,Xinjiang,the mathematical and geological methods of trend surface theory are used to simulate the thick coal in Sha'erhu Sag.In spite of the complexity of the geological situation with large terrain variation,the results show huge reserves and rich coalbed methane resources with a promising future.By establishing a series of processes to calculate the reserves for the area,the study provides a feasible basis for the future exploration.
