Foam Acidification Technology
Source: Time:05-31-2012 Traffic: Read a total of3466Times
Foam acidizing technology is in the conventional acid system by adding a foaming agent and foam stabilizer, foam generator and the gas mixture, the
formation of foam system, with both the foam fluid properties and acidification capacity, sour foam technology is particularly suitable for multi-layer acidification of non-homogeneous reservoir, low
pressure, low-permeability well acidizing, and old wells repeated acidification. Compared with the conventional acidification foam acidification has the following advantages:
Bubble itself selective, you can make more acid into the low permeability layer and formation;
Viscosity, low filtration, penetration ability;
Due to the structure and composition, foamed acid itself has a slowing effect;
A large number of gas bubbles acidification easily flowback less on the production of layer damage.
[Site Application
Typical cases of well: Well Liu 1-3, the well is an old wells into production in 2001, April 6, 2008 liquids production of 3.4 square oil production of 3 tons per day of April 7 1.1 square of a sudden drop in fluid production, production of oil 0.97 tons. Party with my technical staff analysis confirmed that there is blockage, decided to use the foam acidification plugging. The well construction after April 24, 2008 open wells, the initial fluid production side, the oil-producing 23 tons, total liquids production of 755.5 square oil production of 680 tons, fluid level 1729 m, the effect is significant.

The first half of 2008, the company implemented in the Jidong Oilfield foam acidification 20 wells, the success of 19 wells, with 95 percent efficiency.
