AU-32 Water Locking Damage Treatment
Complex factors reservoir damage, water damage is caused by formation damage
the lock to one of the main factors. In the process of completion and operation,
water-based killing fluid, flushing fluid into the formation such as the lock
will cause water damage, especially for the low reservoir pressure (formation
pressure coefficient <1), low water content of oil, more prone to water damage the
lock. In the oil production site, due to frequent killing fluid, flushing fluid loss or
a large number of operating fluid into the formation, resulting in decreased oil
production in the case of even no oil. AU-32 water damage agent is a new oil
field chemicals, it can effectively prevent the formation into the well fluid to enter
the lock after the damage caused by water.
(1) Appearance: colorless or light yellow transparent liquid;
(2) Density: 0.95 ~ 1.05g/cm3;
(3) Temperature: ≤ 140 ℃;
(4) Surface Tension: ≤ 28mN / m;
(5) interfacial tension: ≤ 0.6mN / m
The oil well selection principles:
AU-32 is mainly used for water damage agent: formation of low pressure due
to fluid leakage caused by the operation of wells, the well fluid into the back
row of wells is not easy, as a result of damage caused by fluid into the well after
the decline of the job well.
When the construction operations, the kill fluid, flushing fluid or liquid such
as sand-carrying liquid into the well by adding AU-32 water damage agent, the
concentration of 6% of general application, the AU-32 water damage agent
added into the well mixed solution evenly.
1, in the liquid into the well water used in AU-32 damage agent, can not add other
chemicals, such as cleaning agents, clay anti-swelling agent, as well as exclusive
agent to help, because these chemicals cause harm waterproof AU-32 failure.
2, AU-32 water damage cleaning agent itself has a good role and the role of a good
row to help, so Needless to help re-use of cleaning agents and exclusive agents.
3, if the job requires the use of clay into the well fluid anti-swelling agent, we have
water suitable for AU-32 anti-injury agents dedicated clay swelling agent.
