Description
Technical field
The invention belongs to drilling mud solidification technology fields, and in particular to a kind of drilling well mud prepared by wet grinding
Starch curing materials.
Background technology
Since the 21th century, china natural resources are continuously developed, and gradually turn to industrial power by large agricultural country, although being in
The bottom end of " smile curve ", but be also that China's economic development brings strong impetus to a certain extent.However, in extensive style
Under development of linear pattern, economic fast development is pursued simply, what is brought is that ecological environment is destroyed, and resource is constantly wasted.
The continuous development of process of industrialization, Industrial Solid Waste discharge capacity are continuously increased, and traditional stockpiling and landfill appropriation of land not only pollute
Air and river influence people's health, and seriously having ignored Industrial Solid Waste can be used as raw material to produce building material
This advantage.
In petroleum drilling operation, well drilling waste mud has the characteristics that larger dosage, complex chemical composition, type are more,
Therefore be when handling drilling well waste sludge dress it is extremely difficult, it is now relatively more to the measure taken of these mud dress, but from economy
Benefit is set out consideration, is only had sub-fraction and is recycled, and the overwhelming majority is directly discharged in environment, or take from
It so evaporates, precipitate, consolidating, being buried in the measures progress simply and easy treat such as neighbouring.About ten thousand waste sludges of discharge are betrayed every year in China according to statistics,
It is wherein directly discharged to accounting in ambient enviroment, if do not handled effectively these pollutants, it will to ecological environment
It causes to seriously threaten.
The related patents of published sludge solidifying agent in recent years:Chinese patent CN104529283A discloses a kind of oil field
Waste drilling mud curing materials, it is characterised in that the curing materials are by oilfield waste drilling mud, cement, sand, solidification
Agent and mixing water composition, the mass percent of each component are:Mud:10.0%-50.0%;Cement:10.0%-50.0%;Sand
Son:50.0%-90.0%;Curing agent:0.01%-10.0%;Mixing water:0.0%-10.0%;Chinese patent
CN101696352A discloses a kind of ground pregrouting material prepared with well drilling waste mud.The ground pregrouting material by with
Pre grouting from the surface slurries and the calcium chloride solution composition that well drilling waste mud is prepared;The pre grouting from the surface slurries are given up by drilling well
Mud, cement and structural additives composition are abandoned, structural additives account for 1%~3% (volume hundred in 1 volume pre grouting from the surface slurries
Divide ratio) volume, a concentration of 0.1~0.2g/mL of cement, surplus is drilling mud;Pre grouting from the surface slurries and calcium chloride solution
Volume ratio be 1000: (5~17).
Invention content
The purpose of the present invention is be directed to above-mentioned present situation, it is desirable to provide roadbed material intensity made of a kind of material is high, leaches
Object concentration is low, and every item is up to standard requires, green low-carbon, realizes that drilling mud prepared by the wet grinding that solid waste utilizes is solid
Change material.
The realization method of the object of the invention is that a kind of drilling mud curing materials prepared by wet grinding, are by following methods
It prepares, following each raw materials take parts by weight;Preparation is as follows:
1) 20~25 parts of 25~30 parts of alkaline residue, 15~20 parts of desulfurated plaster, 60~80 parts of flyash and miberal powder are taken, is added to
It is ground in dry mill, obtains average grain diameter<30 μm of mixed powder material;
2) it takes in 60-80 parts of addition wet milks of drilling mud, wet-milling fine to grain size<8 μm, obtain drilling mud material;
3) the mixed powder material that step 1) obtains and the drilling mud material that step 2) obtains first are mixed to get mixture,
Then 1~2 part of SAP of addition in mixture, 1~5 part of NaOH, 0.5~1.0 part of polycarboxylate water-reducer, 1~2 part of ammonium persulfate,
1~2 part of activated alumina, 10~20 parts of mixing waters, 20~25 parts of cement, 30~40 parts of sand, and stirred in concrete mixer
It mixes, drilling mud curing materials is made.
The beneficial effects of the invention are as follows:
1, with wet milling techniques, the highly viscous drilling mud particle of fine increases the mobility of drilling mud, grading
It is more excellent;In the environment of liquid phase is ground, solid particle is destroyed surface energy dissolution active ion, fully excites drilling mud
Lateral reactivity, make drilling mud when other active materials are combined, provided for the material with gelling property can be generated
Basis;
2, it can be provided using alkaline residue, miberal powder a large amount of calcareous;Flyash can provide a part of sa, after mixing with drilling well
Hydration reaction occurs for active ion of the mud in liquid phase (water) environment, generates the material with gelling property, is used as roadbed material
Material, can enhance the intensity and bearing capacity of roadbed material;
3, the heavy metal in drilling mud can be cured using SAP, and can jointly be reduced with desulfurated plaster aqueous in material
Rate;NaOH can provide alkaline environment for hydration reaction, fully excite the hydration activity of raw material;Polycarboxylate water-reducer can enhance brill
The mobility of well mud ensures that drilling mud does not consolidate during reaction;Ammonium persulfate and activated alumina respectively as
Gel breaker and adsorbent further improve the performance of drilling mud, ensure being smoothed out for hydration reaction.
The solid waste of large dosage of the present invention utilizes, and alleviates the waste discharge pressure of enterprise, reduces the stockpiling of solid waste, real
Existing green low-carbon, the process of waste circular regeneration;Curing materials prepared by the present invention are at low cost, function admirable, can meet each
Item performance indicator, is suitable for Ordinary Rd roadbed material therefor.
