Abstract
This invention involves the surplus activation and pollutes proteins as the application of the foam well drilling liquid and prepares the method, utilize surplus active mud person who foam of protein is it foam the pharmaceutical as foam well drilling to use it for, it is to use active mud the impractical law or alkali law that it prepares the method, yes temperature is 110-148 deg.C hydrolysis one hour under the terms, it is appear impurity win protein liquid, and then go protein liquid after the impurity transfer pH value to filter, to a little becoming used as preparing hydrolysising proteins of foam well drilling liquid alkalinly promptly, and then make and foam pharmaceutical and dispose the foam well drilling liquid with the protein hydrolysats. Invention this utilize surplus active mud characteristic of foaming of protein, hydrolysis active mud protein regard as foam well drilling liquid foam the pharmaceutical, its bubble is of good performance, the foaming amount is big, can produce a large number of foam after contacting the gas.
Description
Technical field
The present invention relates to the residual active sludge protein hydrolysate as application of foam drilling fluid and preparation method thereof.
Background technology
In the oil production drilling process, when boring low pressure oil gas-bearing formation, water-sensitive strata and leakiness and easily collapse the stratum, need to adopt foam drilling fluid to prevent that seepage from subsiding.Whipping agent is the key of foam drilling fluid, and the whipping agent that foam drilling fluid is commonly used has sodium alkyl benzene sulfonate, C at present
12-20Alkylsulfonate and sulfonated.These whipping agents are all owing to containing a large amount of sulfonic groups, easily soil, water quality etc. is caused environmental pollution during use, under the High Temperature High Pressure situation, can decomposite hydrogen sulfide simultaneously, cause the drilling tool hydrogen embrittlement fracture, both dangerous, can influence HUMAN HEALTH and contaminate environment again.And good whipping agent must have following characteristics: lathering property is good, and gas release is big, base fluid with can produce a large amount of foams after gas contacts; Froth stability is strong, can be in stable performance under for a long time circulation and the hot conditions, and antifouling property is strong, and is good with resident fluid and working fluid compatibleness, the chemical agent stable performance; Zero pour is low, has biodegradability, and toxicity is little; Preparation foam base fluid consumption is few, and the source is wide, and cost is low; The whipping agent oleophilic hydrophil balance value is in 9～15 scopes.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of lathering property good, non-environmental-pollution, drilling fluid whipping agent high temperature resistant and with low cost---residual active sludge protein hydrolysate is as application of foam drilling fluid and preparation method thereof.
The technical scheme that the present invention solves its technical problem is: the residual active sludge protein hydrolysate is as the application of foam drilling fluid, and residual active sludge protein is as the application of foam drilling fluid whipping agent specifically.
The residual active sludge protein hydrolysate is as the preparation method of foam drilling fluid, be active sludge acid system hydrolysis: promptly adding acid accent PH is 1.0-3.0, in temperature is under 110 ℃ of-148 ℃ of conditions hydrolysis 2-6 hour, filtering and impurity removing matter gets protein liquid, the protein liquid behind the decon is transferred PH to 7.6-8.2 promptly to become as the active sludge protein for preparing foam drilling fluid again; Or use alkaline process, promptly adding alkali accent PH is 11-13, in temperature is under 110 ℃ of-148 ℃ of conditions hydrolysis 2-6 hour, and filtering and impurity removing matter gets protein liquid, the protein liquid behind the decon is transferred PH to 7.6-8.2 promptly to become active sludge protein as the preparation foam drilling fluid again.
Above-mentioned used acid is hydrochloric acid or sulfuric acid, and alkali is sodium hydroxide or lime.
A kind of foam drilling fluid is made up of the raw material of following weight parts:
Tackifier 0.4, stablizer 0.2, whipping agent 4, tackifier are Walocel MT 20.000PV (model MV-CMC), and stablizer is Polyscrylamide (model PAM), and whipping agent is the residual active sludge protein hydrolysate.
Another kind of foam drilling fluid is made up of the raw material of following weight parts:
Wilkinite 5, tackifier 0.1, stablizer 0.2, whipping agent 0.5; Tackifier are Walocel MT 20.000PV (model MV-CMC); Stablizer is Polyscrylamide (model PAM), and whipping agent is the residual active sludge protein hydrolysate.
The present invention utilizes the foaming character of residual active sludge protein hydrolysate, and with the whipping agent of active sludge protein hydrolysate as foam drilling fluid, its lathering property is good, and gas release is big, base fluid with can produce a large amount of foams after gas contacts; Froth stability is strong, can be in stable performance under for a long time circulation and the hot conditions, and antifouling property is strong, and is good with resident fluid and working fluid compatibleness; Can be degraded by Institute of Micro-biology fully, can not pollute environment; The source is wide, and cost is low (to be utilized the residual active sludge that produces in the municipal sewage treatment process again.Domestic food plant effuent, fermentation plant sewage, city domestic sewage all have a large amount of active sludge to produce at present, its treatment process is to sell with the mud landfill or as fertilizer mostly, because heavy metal content is too high, no matter be landfill or all can pollute to environment as fertilizer.Hydrolysed residual active sludge can get a large amount of protein hydrolysates, extracts protein liquid from residual active sludge, and raw materials cost is zero substantially, and extraction process simply make foam drilling fluid one-tenth with this protein should be very low, product cheap).
