Abstract
The invention discloses a method for optimizing blowing agent concentration. The method for optimizing the blowing agent concentration comprises the following steps: adding blowing agent solutions of different concentrations into a measuring pot; stirring at a high speed; reading the foam volume; testing the time required for separating out 50ml of liquid from the foam; and comparing the foam volume with the time data to determine the optimum concentration and the like. The method can be used for determining the optimum concentration of the blowing agent, is simple to operate, is short in detection time, is low in detection cost and is beneficial to popularization.
Description
Technical field
The present invention relates to a kind of method for optimizing of foaming agent concentration.
Background technology
Foam is a kind of unsettled substance system, and the screening of frothing agent is the important process during all aerated fluids are used with estimating, and different application purposes has different requirement for frothing agent.Dissimilar frothing agent adaptability have bigger difference, and foam fracturing fluid mainly contains following requirement for frothing agent:
(1) frothing capacity is good, foam base fluid with can produce significant foam after gas contacts, promptly the foam volume expansion multiple is high.
(2) foam has better stability.
(3) contamination resistance is strong, and is good with other fluid compatibility.
(4) consumption is few, and cost is low.
(5) it is abundant that frothing agent is made raw material, and the supply source of goods is extensive.
The frothing agent performance is mainly estimated from two aspects, and the one, foamability is stability on the other hand.
Frothing agent commonly used mainly contains several types such as anionic frothing agent, nonionic frothing agent, compound frothing agent, superpolymer type frothing agent, and the basic frothing capacity difference of various frothing agents is bigger.
Foaming agent concentration is the key factor that influences foaming volume and half life period, also is the basis of carrying out follow-up evaluation.When confirming foaming agent concentration, should consider the performance of foam, also will consider economy.Through measuring the foaming volume and the half life period of frothing agent under the variable concentrations, calculate variable concentrations foam integrated value down, and with this as main evaluating, confirm the working concentration of frothing agent in the follow-up use.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of above-mentioned prior art; A kind of method for optimizing of foaming agent concentration is provided; The method for optimizing of this foaming agent concentration can be determined the optium concentration of frothing agent, and simple to operate, and detection time is short, the detection cost is low, be beneficial to popularization.
The object of the invention is realized through following technical proposals: a kind of method for optimizing of foaming agent concentration may further comprise the steps:
(a) respectively the foaming agent solution of variable concentrations is added in the different measuring cups;
(b) carry out the high-speed stirred certain hour respectively after, close whip switch;
(c) read the foam volume in each measuring cup, thereby obtain a plurality of foam volume data, this foam volume is the foaming capacity of frothing agent at once;
(d) write down each measuring cup respectively and from foam, separate out the required time of 50ml liquid,, thereby obtain a plurality of half life period, be the stability of frothing agent as the half life period of foam;
(e) compare foam volume data and the half life period that above-mentioned steps obtains, thereby confirm optimum foaming agent concentration.
In the said step (a), foaming agent solution is 100ml.
In the said step (a), the concentration of foaming agent solution is 1.00g/L.
In the said step (b), stirring rate is greater than 1000r/min.
In the said step (b), stirring rate is 8000r/min.
In the said step (b), mixing time is 3 minutes.
Said frothing agent is the lauryl sodium sulfate frothing agent.
In sum, the invention has the beneficial effects as follows: can determine the optium concentration of frothing agent, and simple to operate, detection time is short, the detection cost is low, be beneficial to popularization.
