Description
Technical field
The present invention relates to a kind of oil production with environment-friendly type can be repeatedly crosslinked vegetable jelly water plugging profile control agent and preparation and application.
Background technology
Along with deepening continuously of water flooding, many oil fields have been in the middle and high Water-cut Period development phase, and the Water in Water Shutoff in Oil Field profile control technique has become an important process technology in waterflooding heterogeneous body oil field.Field practice proves, the Water in Water Shutoff in Oil Field profile control technique can effectively reduce the oil well water production rate; Improve well oil output, improve the ununiformity of water injection well suction, thereby improve water injection well sweep efficiency longitudinally.Increase the stage recovery percent of reserves of workable reserve and the raising water flooding in oil field, and finally improve the recovery ratio of water flooding.
The gel-type plugging agent is a present most widely used class plugging agent, most typical example is take polyacrylamide solution as host, and take chromium, zirconium or aluminum ion as linking agent, but this type of frozen glue anti-shear ability is poor, crosslinking reaction speed is fast, and the consumption that increases delayer can cause gel-strength to descend; With terpolycyantoamino-formaldehyde resin or the gel plugging agent take the hydroxy derivatives of phenol as linking agent, can extend the infusion time, but intensity is low, and formaldehyde can produce larger pollution to the site operation environment; With polymer monomer and N, the Gelling Plugging Agent that N '-methylene-bisacrylamide and chemical initiator copolymerization form, its initial strength is higher, but heat resistance is poor, anti-shear ability is poor, and strength decreased is fast, and the toxicity of monomer is stronger.Chinese patent CN1085590A adopts organosilane and yin, yang, non-ionic monomer to form a kind of high molecular polymer in the aqueous solution, the gel salt-resistant temperature poor-performing that this technology forms, a large amount of polymer monomer, highly basic, nitrogen etc. of using in production.Chinese patent CN1351106A adopts sulfoaluminate clinker fine powder, anhydrite and wilkinite etc. to form inorganic blocking agent, and this blocking agent ultimate compression strength is low, and the delayed gel time is short.Chinese patent CN101033392A adopts high polymer polyacrylamide and boron modified phenolic resin delayed crosslinker to form the temperature resistant antisalt blocking agent, but this blocking agent intensity is low, and breakthrough pressure gradient is little, and the not environmental protection materials such as a large amount of contact phenol, formaldehyde in production process.
Summary of the invention
Pin the purpose of this invention is to provide a kind of environment-friendly type repeatedly crosslinked vegetable jelly profile-controlling and plugging agent and preparation and application, does not pollute stratum and ground environment when realizing effective water plugging and profile controlling.
The present invention has developed repeatedly crosslinked vegetable jelly water plugging profile control agent and preparation method thereof of a kind of environment-friendly type, utilizes this plugging agent that crosslinking reaction formation can occur under 50 ℃～90 ℃ formation conditions and has high-intensity plant colloid.The gelation time of system can be chosen as 4h～10d as required, can again occur crosslinkedly through meeting after shearing continuously, and keeps integrity and the high strength of colloid, guarantees effectively carrying out of water plugging and profile controlling measure.
Environment-friendly type of the present invention repeatedly crosslinked vegetable jelly plugging agent includes xanthan gum, and natural toughener, stablizer and water, the part by weight of above-mentioned each component are 0.5: 1.5: 0.3: 100, make the vegetable jelly product in this ratio by special process.This vegetable jelly product is made dry powder, prepare the vegetable jelly plugging agent with water according to the weight ratio of 3: 100, this blocking agent is a kind of weak yellow liquid, and 25 ℃ of lower viscosity are less than 100mPas, and swelling 12h～10d can form the high strength blocking agent under 50 ℃～90 ℃ conditions of formation temperature.
The xanthan gum that adopts is pale yellow powder; Natural toughener is Rhizoma amorphophalli powder; Stablizer is selected but is not limited only to sodium carbonate.
This environment-friendly type repeatedly preparation method of crosslinked vegetable jelly plugging agent is as follows:
1. at ambient temperature, the raw materials such as xanthan gum, natural toughener, stablizer are mixed according to a certain percentage.
2. said mixture material and water at the uniform velocity are added to the water under agitation condition according to a certain percentage, the reinforced complete rear 100 ℃ of constant temperature water bath heating 2h that directly put into, the thermosol that takes out is treated the plastic placement under 50 ℃～60 ℃ environment, 0～10d post-drying grinds the product powder that can obtain repeatedly cross-linked environment-protective vegetable jelly plugging agent of the present invention.
3. vegetable jelly blocking agent product mixed according to a certain percentage and slightly mixes with water, being placed in formation temperature (50 ℃～90 ℃) loft drier, 12h～10d can obtain repeatedly crosslinked vegetable jelly plugging agent of environment-friendly type of the present invention.
Through laboratory proofing, this product curing time sum when plastic storage period and application product of thermosol in process of production is the 10d left and right, place the 8d post-drying as thermosol and grind under 50 ℃～60 ℃ environment, the gelation time during product application is the 2d left and right; Grind and place the 10d post-drying under 50 ℃～60 ℃ environment as thermosol, the gelation time during product application is the 12h left and right.This product colloid was soaked for 1 week in a large amount of clear water, shape and the intensity of colloid all do not change; This product colloid is at 200s
-1Rotating speed under shear continuously the particle shape that becomes thickness after 30min, shear that to stop rear 40min can be again cementing gluey for complete plant, and Strength retention is constant.
