Water dispersion composite sand-fixing agent formula

Abstract

The invention relates to a formula of water dispersing compounding sand consolidation agent. It is made up from modified phenol-formaldehyde resin 5-8%, organic silicon resin 0.02-0.25%, furfural compounding 5-15%, alcohol compounding 0.5-5%, phosphoric acid series compounding 0.05-0.15% and water 89.43-81.6%. The benefit is that the sand consolidation agent has low viscosity, low usage quantity, low cost, etc.

Description

1. Technical field:

[0001] The invention relates to a formulation of a composite sand-consolidating agent, in particular to a formulation of a water-dispersed composite sand-consolidating agent. 2. Background technology:

[0002] At present, the chemical sand control and sand consolidation technology of oil and water wells is to solve the problem of sand production in oil and water wells. well and borehole wall sand-fixing technology, sand-fixing water plugging and sand-fixing plugging removal technology, fracturing sand control technology, and sand-fixing formation pretreatment technology, but the sand-fixing agent cannot be applied to all formations, especially in solving multiple There are problems in stratification and layer selection for sand control in multilayer wells. The curing agent has disadvantages such as poor pumpability, large dosage, large loss of permeability, and low compressive strength. It is not suitable for sand production wells with low clay content. ...
