Abstract
A high-strength sand-curing agent is used to improve crude oil recovery rate and extract sand-proof condensed oil well. It consists of main agent solid sodium silicate, organic titanate coupling agent and metal oxide. The process is carried out by grinding into powders with grain size 0.03-0.06 mm, mixing with stratum sand and curing into hard binding system at 120 degree hydrous medium. It's safe, simplified and cheap, has better strength and penetration rate.
Description
Technical field:
The present invention relates to a kind of oil field chemical, in particular for the raising oil recovery factor with steam stimulation mode heavy crude producing well sand control aspect.
Background technology:
There is the problem of shaking out in the heavy oil wells of part exploitation via steam injection, and can adopt usually annotating the method that vapour injects the high temperature sand-fixing agent latter stage and come consolidating stratum, reaches the sand control purpose.There is following point in high temperature sand-fixing agent commonly used at present:
1. reagent cost height;
2. consolidation strength is low;
3. range of application is narrow;
4. oil well productivity descends after the measure.
Summary of the invention:
The objective of the invention is to develop a kind of high-strength sand-fixating agent, overcome the problem of high temperature sand-fixing agent existence in the past, make the sand control life of thick oil thermal extraction longer, measure cost is lower, and input-output ratio significantly rises.
High-strength sand-fixating agent of the present invention is a host with the sodium silicate solid, doses an amount of titanate coupling agent and metal oxide etc., and it constitutes:
Water glass: 80～100 parts (weight, as follows)
Titanate coupling agent: 1～2 part
Metal oxide: 10～20 parts
Metal oxide is zirconium white, cupric oxide, aluminum oxide and magnesium oxide or zinc oxide etc. in the high-strength sand-fixating agent of the present invention.
Grind to form the meal that particle diameter is 0.03～0.06mm after above-mentioned composition prepared, be referred to as the high strength solidifying agent.With this agent and a certain amount of reservoir sand mixing, in being higher than 120 ℃ water medium, temperature can be solidified into insoluble infusible hard bonding system.This system has higher intensity and bigger rate of permeation, thereby reaches the purpose that sand control recovers the oil.
High-strength sand-fixating agent of the present invention has replaced the silicone resin in the high temperature sand-fixing agent based on inorganic cementitious material, makes reagent cost reduce more than 50%; Improved the composition of cementing matter in the sand-fixing agent, made the consolidation strength of sand-fixing agent rise to 5～10MPa by original 2MPa, the significantly rising of consolidation strength has significantly improved the efficient and validity period of sand control; Increased the ratio of solubility upholder in the sand-fixing agent, sand-fixing agent is reacted in the stratum after, Gu sand body still can keep good perviousness, do not influence the production capacity of oil well; Added effective catalyst, improved the reactive behavior of sand-fixing agent, made it to reduce to 120 ℃ by 180 ℃, enlarged range of application with the temperature of reaction of reservoir sand; Improved production technique, developed into the series product of different-grain diameter scope, improved the matching relationship of sand-fixing agent and stratum pore throat, can adapt to the sand control requirement of Different Strata condition by single product cut size in the past; Simplified construction technology, improved the construction safety coefficient, for the large-scale promotion application of this product has been created condition.
Embodiment:
Embodiment 1:
With 85 parts of (weight) sodium silicate solids, 1 part of titanate coupling agent, 15 parts of zirconium whites, wear into the meal that particle diameter is 0.03～0.04mm, be made into the high strength solidifying agent.With this agent and a certain amount of reservoir sand mixing, in being higher than 120 ℃ water medium, temperature can be solidified into insoluble infusible hard bonding system.
Embodiment 2
With 115 parts of (weight) sodium silicate solids, 2 parts of titanate coupling agents, 20 parts of zirconium whites, wear into the meal that particle diameter is 0.04～0.05mm, be made into the high strength solidifying agent.With this agent and a certain amount of reservoir sand mixing, in being higher than 120 ℃ water medium, temperature can be solidified into insoluble infusible hard bonding system.
Embodiment 3
The neat 108 neat 108-23-23 well sand control treatments in Liaohe Oil Field:
Neat 108-23-23 well is exploited in the steam stimulation mode, well section 1459.5～1478.1m, and the 7.9m/2 layer, 20 days under production is that sand buries oil reservoir, sand washing 2.5m
3Can not keep ordinary production.
The foregoing description 2 is made into high strength solidifying agent 0.7t high-strength sand-fixating agent is mixed with 10% water base suspension, when steam treatment finishes, inject sand control zone of interest position, stewing well 48h, following pump is gone into operation.Recover a day produce oil 3t, day production fluid 8m
3, two rounds of ordinary production are not seen and are shaked out, sand controlling result is very obvious.
