Abstract
The invention relates to an adjusting section method of a HT three phase foam-adjusting agent. Its composition comprises HPAM 0.4-1.2%, PF resins cross linker 0.1-0.8% and the heating stable inhibitor. It can be used in the 300deg.C and the capping rate is 90%, the intensity of it is 12MPa/m. So the agent reached the integral of the adjusting-stifled in high temperature and assist-injection. So it saves cost of the process.
Description
Technical field:
The present invention relates to oil-field thick-oil and annotate the water plugging and profile controlling operation chemistry injecting of vapour recovery well, particularly a kind of high temperature foaming triphase profile control agent profile control method.
Background technology
Because the characteristic and the exploitation via steam injection of reservoir, along with the increase of the round of handling up, the raising of recovery percent of reserves, accent blocks up and the row of helping has become the indispensable measure of heavy oil steam injection recovery well.Kind surplus the oil and water well amendment of having used has 30, these blocking agents are mainly used in conventional the oil recovery, and part can be applicable to high temperature water plugging and profile controlling such as cement, some resin and the inorganic precipitation etc. of thick oil thermal extraction.Block up at accent, aspect two kinds of technologies of the row of helping combine, above-mentioned amendment is because the temperature tolerance of medicament is poor, and can not be applied to annotate the vapour well.
Summary of the invention
The object of the present invention is to provide a kind of high temperature foaming triphase profile control agent, the aboveground use of heavy oil steam injection recovery that can be in oil-gas field, effectively control the thermal recovery well water outlet, adjust annotate that vapour cuts open and, shutoff vapour scurries, water breakthrough; Simultaneously, the high temperature foaming triphase profile control agent has the good effect of peeling off and prevents steam condensate and viscous crude formation water-in-oil emulsion the deposition oil film of rock surface in the stratum after the aquation, plays the row of helping and acts on.
The object of the present invention is achieved like this, and the molecular weight that takes by weighing different ratios at first respectively is HPAM0.4～1.2% more than 1,000 ten thousand; Phenolic resin crosslinking agent 0.1～0.8%, thermo-stabilizer 0.1～0.8%, solid phase particles and water 2～10%; Then each solid components is mixed with mixing machine; By jet hopper each component water is carried during use, form the stable suspended dispersed system of glue, inject the down-hole.
The present invention is owing to adopted HPAM0.4～1.2%; Phenolic resin crosslinking agent 0.1～0.8% and thermo-stabilizer, make high temperature foaming triphase profile control agent heatproof reach 300 ℃, sealing ratiod to rock core under 300 ℃ reaches 90%, plugging strength is greater than 12MPa/m, in the aboveground use of heavy oil steam injection recovery, effectively control the thermal recovery well water outlet, adjust steam entry profile, shutoff vapour is scurried, water breakthrough; Simultaneously, the deposition oil film of rock surface there is the good effect of peeling off and prevents steam condensate and viscous crude formation water-in-oil emulsion, play the row of helping and act on.The high temperature foaming triphase profile control agent realized high temperature transfer block up, the row of helping is integrated, solve accent block up, when the row of helping constructs respectively, the contradiction between the measure, economy expense.
Embodiment
The molecular weight that takes by weighing different ratios at first respectively is the HPAM0.8% more than 1,000 ten thousand; Phenolic resin crosslinking agent 0.5%, thermo-stabilizer 0.5%, solid phase particles and water 7%; Then each solid components is mixed with mixing machine; By jet hopper each component water is carried during use, form the stable suspended dispersed system of glue, inject the down-hole.High temperature foaming triphase profile control agent heatproof reaches 300 ℃, and the sealing ratiod to rock core under 300 ℃ reaches 90%, and the big 12MPa/m of plugging strength, gel hydrating fluid can suppress viscous crude and steam condensate forms water-in-oil emulsion.
