1. Introduction The clean fracturing fluid produced by the
company is also designed and developed by the company; with a complete
formulation and production and testing equipment. The conventional system is
properly adjusted in the process of polymerization in terms of different
temperatures, geological conditions and fracturing technologies in order to meet
the customer requirements.
2. Technical Characteristics (1)The clean fracturing fluid
system is an anionic surfactant. As sulfonic acid group is introduced, its
resistance to temperature and salt is increased. In addition, the anionic
surfactant is of the same properties as the formation, so it is not absorbed by
formation, hence reducing the damage to formation in immediate vicinity of
(2)The clean fracturing fluid system has fast dissolution rate and
dissolves uniformly, with its viscosifying time at 10min, so it is suitable for
field preparation and use.
(3)This clean fracturing fluid system is not much
affected by biodegradation factors, so it is suitable for long-time storage; as
a natural organic polymer, guar gum is easily biodegradable.
resistance to shear and temperature and its rheology are better than similar
products; (See Qualification Documents for the testing reports by Research
Institute of Petroleum Exploration & Development (RIPED) Langfang Branch and
SINOPEC Research Institute of Petroleum Engineering).
(5)It has extensive
sources of raw materials, which would not be affected by international market,
with stable cost price.
(6)Low residue level (≤ 70mg/L; guar gum ≥
(7)Small formation damage rate (≤20%; for guar gum, 10%~50%)
