Abstract
The invention relates to an acidic crosslinking agent applied to hydroxypropyl guar gum and a preparation method thereof. The traditional crosslinking agents need to carry out crosslinking under the alkaline condition and have poor gelatinizing effect under the acidic condition. The acidic crosslinking agent is characterized by comprising the following raw materials by weight: 45-55 parts of glycol, 20-30 parts of glycerol, 10-20 parts of tetrabutyl titanate and 5 parts of citric acid. The preparation method is characterized by comprising the following steps: weighing the raw materials according to the parts by weight; uniformly mixing and heating the raw materials except tetrabutyl titanate and adding tetrabutyl titanate after the temperature reaches 100 DEG C; continuing heating the raw materials to 120-140 DEG C and preserving heat for 3-4 hours; and cooling the product obtained in the previous step to the room temperature, thus obtaining the liquid, namely the acidic crosslinking agent. The acidic crosslinking agent and the preparation method have the following advantages: 1. the acidic crosslinking agent and the preparation method are suitable for acid systems; and 2. the synthesis process is simple and convenient.
Description
Technical field
The invention belongs to the linking agent technical field of oil field hydroxypropylguar gum pressure break system, be specifically related to a kind of acidic crosslinking agent that is applied to hydroxypropylguar gum and preparation method thereof.
Background technology
Pressure break is the important means of oilfield stimulation, and is especially low at three--low abundance, hyposmosis, low-producing oil field.What most of pressure break adopted is aqueous fracturing fluid, and hydroxypropylguar gum is to use maximum water base fracturing fluid thickening agents, and the of the fracturing fluid advantage of hydroxypropylguar gum is the viscosity height, and it is strong to take husky ability, and broken glue residue content is low, and is little to reservoir damage.Linking agent plays keying action in oil field compression fracture, thereby can make the mutual bonding cross-linking of a plurality of thread-like molecules become the material of tridimensional network by the intermolecular bridge formation in hydroxypropylguar gum.
At present, the hydroxypropyl guar fracturing fluid linking agent of domestic preparation, what generally adopt is based on organic boron.These traditional linking agents need be crosslinked under alkaline condition, becomes the glue effect bad under the acidic conditions, even can not form jelly, is not suitable for the quick property of alkali stratum etc., influenced result of use.
Summary of the invention:
The object of the present invention is to provide a kind of acidic crosslinking agent that is applied to hydroxypropylguar gum and preparation method thereof, to overcome prior art organic borate cross-linker one-tenth glue weak effect that under acidic conditions, exists and the problem that is not suitable for the quick property of alkali stratum.
To achieve these goals, the technical solution used in the present invention is:
A kind of acidic crosslinking agent that is applied to hydroxypropylguar gum, its special character is: the raw material and the weight proportion of described acidic crosslinking agent are as follows:
Ethylene glycol 45-55 part,
Glycerol 20-30 part,
Tetrabutyl titanate 10-20 part,
5 parts of citric acids.
The above-mentioned preparation method who is applied to the acidic crosslinking agent of hydroxypropylguar gum, its special character is: comprise following processing step:
1) take by weighing raw material by above-mentioned weight part,
2) will mix except that the raw material except the tetrabutyl titanate and heat, treat to add tetrabutyl titanate after the temperature to 100 ℃,
3) continue to be heated to 120-140 ℃, insulation 3-4h,
4) the previous step product is cooled to room temperature, the liquid that obtains is acidic crosslinking agent.
With respect to prior art, advantage of the present invention is:
1, is fit to acid system
The present invention is fit to acid system, crosslinkedly becomes the frozen glue tolerable temperature higher, and taking grittiness can be good, can be applied to the quick property of alkali stratum, has expanded the crosslinked applied environment of hydroxypropyl guar fracturing fluid.
2, synthesis technique is easier
Add citric acid in the synthesis technique, made whole reaction system pH keep constant, simplified the operation steps in producing.
