- 摘要:
- 为研究页岩气储层评价中主要参数的作用，有必要分析各参数的影响机理。在调研国内外研究进展的基础上，以美国五大盆地页岩气勘探开发认识为参考，分析总有机碳含量、含气量、温度和压力等参数对储层评价和开发的作用。发现页岩气储层评价比常规储层研究更复杂，多项评价参数对储层有正反两方面的影响，单一控制因素的优劣不能定性评价储层，页岩气体储集包含吸附态、游离态、溶解态，吸附解吸作用使其渗流规律异于常规储层，因此页岩气储层有利区块的优选需要进行多种指标的综合考虑.
In order to analyze effects of main parameters in shale reservoir evaluation， it is necessary to analyze mechanism of these parameters. Investigated are the research progresses in this issue at home and abroad， referred are shale gas exploration and development in five basins of America and analyzed are effects of such parameters as total content of organic carbon， gas content， temperature and pressure on shale gas reservoir evaluation and development. It is found that shale gas reservoir evaluation is more complex than conventional reservoirs， a number of evaluation parameters have both positive and negative effects on the reservoir. The nature of the evaluated reservoir can not be determined by using any single parameter. Shale reservoir contains adsorption gas， free gas and dissolved gas， its adsorption and desorption effects make its percolation behaviors different from any conventional ones. As a result， favorable area preferential selection of shale reservoirs requires comprehensive consideration of various evaluation parameters.
