塔里木盆地巴楚-麦盖提地区石炭系碎屑岩储集层评价

在塔里木盆地巴楚—麦盖提地区石炭系碎屑岩储集层评价中为了客观地研究储集层质量与油气生成、运移的匹配关系，应用沉积相研究方法，对成岩作用及影响储集层性能的诸因素进行了综合分析，认为压实、胶结作用导致石炭系碎屑岩孔隙减少；溶蚀、交代作用形成次生孔隙，改善了储集物性；中新世前的石炭系东河砂岩，在研究区的东部和西部为良好储集岩，而现今储集层质量较差；卡拉沙依组碎屑岩在早第三纪前为好的储集岩

EVALUATION OF CARBONIFEROUS CLASTIC RESERVOIR IN BACHU- MAIKIT AREA, TARIM BASIN

Based on controls on reservoir developing, applying study method of sedimentary facies and study on diagenesis, the relation between reservoir quality and oil/gas generation, migration in Bachu-Maikit area of Tarim basin was comprehensively analyzed, the results showed that compaction and cementation resulted in porosity decrease in clastic rocks, while denudation and replacement formed secondary pore, improving physical property of reservoir. It is considered that Carboniferous Donghe sandstone before Miocene was better reservoir rock in eastern and western study area, Kalashayi formation clastic rock was welldeveloped reservoir before Paleogene. However, these reservoirs become worse after Miocene and Paleogene.
