Testing example 1
The preparation of active water:By the PAMA of 0.25g, (weight average molecular weight is 3 × 106)
It is dissolved in the water of 488.65g, is well mixed, obtains viscous water;The OP-10 of 1g is dissolved in acquisition
In viscous water, it is well mixed;10g potassium chloride is added, is stirred;Add 0.1g formaldehyde, stirring
Uniformly.
Test method:By embodiment 1-8, comparative example 1-5 from suspended prop respectively in active water
Liquid viscosity, solid-carrying performance and frictional resistance parameter testing are carried out, viscosity determining procedure is referring to standard
(SYT5107-2005);Sinking speed is determined and uses 0.5m lucite tubes, loads 45cm work high
Property water and sand than the proppant for 30%, shake up the sinking speed of test proppant;Frictional resistance uses DV-III
Viscosimeter, configuration 30% sand than pressure break system, rotating speed is 100rpm, and the moment of torsion for determining them carrys out table
Levy the frictional resistance of proppant.Test result is as shown in table 1 below:
Table 1
From table 1 data can be seen that prepared by expanding material composition of the invention from suspended prop
Possess excellent prop-carrying capacity and drop frictional resistance ability in active water.From embodiment 1-8 and comparative example 1-5
Data Comparison can be seen that prepared by expanding material composition of the invention from suspended prop with do not make
The proppant aggregate of any cladding and only coat binding agent and compared with the proppant aggregate of curing agent, its
Sinking speed and frictional resistance are lower, and the viscosity of the active water for obtaining is also smaller, illustrate expanding material of the invention
Prepared by composition possesses more excellent prop-carrying capacity and drop frictional resistance ability from suspended prop;It is of the invention
Be applied in combination for polyvinyl alcohol and semi-synthetic macromolecular material by expanding material composition, than poly- second is used alone
Enol is used alone semi-synthetic macromolecular material all with more preferable effect;And it is water-soluble high using other
The resulting effect that molecule substitutes polyvinyl alcohol is poor.From the data of embodiment 4-6 it can also be seen that
When doing aggregate using precoated sand, the taking from suspended prop prepared by expanding material composition of the invention
Sand ability and drop frictional resistance ability are more prominent.
