Description
Technical field
The present invention relates to a kind of oil field cleaning antiscale formula and preparation methods, especially relate to hypotonic complicated fouling reservoir
Cleaning antiscale formula and preparation method thereof.
Background technology
It is inevitable to generate formation solids intrusion, foreign liquid in the drilling well of early field life, formation testing, oil recovery process
With water flooding mixed precipitation, the precipitations such as paraffin, colloid, asphalitine easily cause formation blockage；Into development phase intermediary and later stages, with
The increase of water content in exploitation, fouling is more universal and serious.Oil field water fouling leads to producing well, water filling well shaft, recovers the oil
Pump and device systems block, and lead to equipment scrapping.For low-permeability oilfield, pore throat diameter is small, and formation sensitivity is strong, and formation scaling is tight
Ghost image rings the normal production of oil gas, directly affects oil gas well production, reduces Oil & Gas Productivity；Water-injection efficiency is reduced, payzone is influenced
Energy supplement reduces the ultimate recovery in oil field.
The degree of oil layer pollution is different, various informative, complicated mechanism, inorganic scale and organic deposition is generally included, frequently with acid
Dissolve stifled, biological plugging releasing and solvent de-plugging.
CN103484088A discloses a kind of de-plugging agent suitable for complex lithology reservoir acidification.The de-plugging agent passes through hydrochloric acid
Hydrazine and fluorochemical slowly generate HF in reservoir, achieve the purpose that slow, are suitble to store up due to oil layer pollution caused by clay
The processing of layer.
CN103555307 discloses a kind of blocking remover for oil extraction, can by the colloid of attached knot in oil recovery well shaft, pitch,
Wax etc. blocks substance dissolving, to solve pit shaft blockage problem.
CN102504785 discloses a kind of oil field biological blocking remover and preparation method thereof, and main component is withered grass gemma
The culture solution of the fermented gained of bacillus has at low cost, good environmental protection, corrosion-free to oil field pipe and underground equipment, can give birth to
The advantages that object is degraded.Acidizing unblocking technique, including self-generating mud-acid, buffering adjusting acid, buffer regulated HF acid, fluoboric acid, phosphoric acid etc.,
There is certain solution ration to inorganic scale, part inorganic scale can be released and permeate damage caused by stratum, and to pitch, wax
The plugging removal effect of equal Organic Material Blockings is then very poor.The blocking that enzyme used by biological blocking remover can be generated with degradation polymer, needs
Inorganic scale or organic deposition can just be removed by being cooperateed with acid or other solvents, and the activity of enzyme is narrow to temperature and pH value accommodation, existing
Stage is difficult to meet field demand.
The above patent the problem is that：It is only capable of being removed inorganic scale or organic deposition, organic deposition can not be removed simultaneously
The blocking formed with inorganic scale.In order to which the fouling preferably solved in oilfield water extraction injures this technical barrier, it is necessary to
For hypotonic complicated fouling reservoir scale problems, a kind of multi-functional cleaning antiscale is researched and developed to reduce inorganic scale and organic deposition blocks
Problem increases considerably antiscale range, extends the measure term of validity.
Invention content
The purpose of the invention is to provide the multi-functional cleaning antiscale formula of the hypotonic complexity fouling reservoir of one kind and preparation sides
The compatibility of method, the cleaning antiscale and reservoir fluid is good, and anti-scaling action range is big, and the de-plugging blocked to organic matter, inorganic matter is imitated
Rate is high, can solve that existing cleaning antiscale is only strong to inorganic scale removal ability, to the problem of organic deposition releasing effect difference.
The present invention is realized by using following technical proposals：
A kind of multi-functional cleaning antiscale formula of hypotonic complicated fouling reservoir, is made of the following components of weight percent：Have
