| 摘 要： | 本文通过矿物使用的钻井液和酸化解堵液对储层岩石所作的损害评价试验证实，该区储层产能低的原因之一是钻井液和酸化解堵液使储层渗透率损害达35％－75％造成。针对该区储层实际，采用作者研制的酸液解堵模拟试验证实，可使储层渗透率恢复到原始值的89％－185％，平均恢复至原始值的110％，适用于该区储层的酸化解堵。

| Abstract: | Trough the experiment of damage to reservoir rock,caused by drilling and acidizing fluid, this paper revealed that one of the causes of low productivity in the Nanyang sag is the damage of drilling and acidizing fluid to reservoir permeability,which reached 35%~75%.In order to solve the problem,we made simulation test by using acidizing fluid developed by us to eliminate the blokage in the reservior.The test achieved effective result,characterized by recovery of reservior permeability to 89%~185%,with an average value of 110%.The acidizing fluid proved to be suitable for the blokage elimination in the reservior of the Nanyang sag. |
