Abstract
The invention provides a resin filler for fracturing and its preparation method, belonging to the technical field of oil exploitation. The resin filler comprises styrene, acrylamide, anionic monomer, a cross-linking agent, a plasticizer, a coupling agent, a curing agent, a filler, white oil, an emulsifier, etc. The resin filler is prepared by subjecting styrene and anionic monomer to inverse emulsion polymerization and carrying out high-pressure spraying, cooling and other physical means after completion of inverse emulsion polymerization. The resin filler for fracturing has certain elasticity, strong anti-fracture capability and high strength due to addition of the anionic monomer.
Description
Technical field:
The present invention relates to technical field of petroleum extraction, be specifically related to a kind of pressure break resin filler and preparation method.
Background technology:
Fracturing propping agents are that oil, natural gas extraction fracturing operation process are for supporting the solid with some strength of rock seam
Grain.During fracturing operation, fracturing propping agents are mixed in fracturing fluid, utilize high pressure tactics that proppant is injected deep layer rock seam
In, it is used for supporting rock seam, forms the passage of high osmosis, make oil or natural gas flow out from these cracks.The most both at home and abroad
Commonly used sintering ceramsite is as fracturing propping agents.Various in the underground activities of deep layer, stratum to be born of fracturing propping agents
Corrosion, so fracturing propping agents to have good acid resistance.
In Oil/gas Well hydraulic fracturing job, a major issue selects suitable proppant supporting crack exactly, preferable
Proppant should have the following characteristics that 1, relative density little, it is simple to pump into underground；2, intensity is high, will not in heavy duty service
Crushed；3, chemical inertness is good, can resist oil in stratum, acid, the erosion of saline, the most stable；4, circularity is good, with
Just preferable space between proppant particles is ensured；But, it is difficult to more than satisfied to the conventional proppants of sand, the such class of haydite
Condition.
Sand is the most conventional proppant, and relative density is about 2.5.Because it is cheap and easily-available, centering, deep-well all kinds of
Stratum uses sand to be that proppant has certain success rate, but because sand insufficient strength is high, therefore cannot be used in heavy duty service.
In the case of closure stress is higher, sand grains will be crushed, produces substantial amounts of fragment and fine silt.These fine silts are in crack
Middle migration also blocks crack, thus greatly reduces the flow conductivity in crack.
Haydite can be divided into again two big classes according to material difference: intermediate-strength proppant and high strength support agent, haydite
Expensive, it is generally limited in the stratum that clossing pressure is high use, haydite class proppant is the most expensive, more important
Be due to relatively denser, in construction, require that the viscosity of load fluid must be high, energy expenditure is very big, and whole operating expenses is also
The highest.
In hydraulic fracturing job, use the proppant of both types to also have a unsurmountable shortcoming, i.e. they
Stratum can be embedded or occur when Oil/gas Well puts into production proppant to spue or crack emptying phenomenon, ask to solve above-mentioned technology
Topic, a kind of new technical scheme of special proposition.
Summary of the invention:
The present invention is directed to that prior art exists proppant is broken, proppant spues or crack emptying phenomenon, and can not be over the ground
Layer carries out the defect of effective pressure break, it is desirable to provide a kind of pressure break resin filler, reduces the density of proppant, improves and prop up
The shortcomings such as support agent is broken.
