| Abstract: | Advanced micro cross link technology is applied to research model JB low damage operating fluid for resolving reservoir damage caused by water sensitivity and other factors in Penglaizhen sector and Shaximiao sector, Xinchang gas field. Lab tests and field applications in 4 wells show that the fluid has such characteristics, low circulation loss, returnable and low cost, etc. The permeable recovery ratio of core is over 70%, so that it can reduce reservoir damage remarkably and is worth popularizing. |
