为了研究塔中碳酸盐储层钻探开发过程中储层的损害机理,通过进行储层岩性、物性、储层流体性质分析和岩心敏感性实验研究,可知储层敏感性整体偏弱,弱速敏,水敏中等偏弱,盐敏中等偏弱,强碱敏,无酸敏,应力敏感较强。该区块需要选择合适的生产压差及控制入井流体的密度,钻井完井液体系宜采用高矿化度、低pH工作液体系,在开发生产过程中可采用增产措施。 In order to study the damage mechanism of reservoirs during the drilling and development of carbonate reservoirs in the Tazhong area, reservoir sensitivity, lithology, reservoir properties and core sensitivity were studied to show that reservoir sensitivity is weak and weak Fast-sensitive, water-sensitive medium weak, moderate salt weak, strong alkali sensitive, acid-free, strong stress sensitivity. The block needs to select appropriate production pressure and control the density of fluid entering the well. The drilling and completion fluid system should adopt the high salinity and low pH working fluid system, and the stimulation measures can be adopted during the development and production.
