Abstract
The present invention relates to a method for producing a high temperature sand consolidating agent which is used for preventing mud and sand from flowing into a wellbore through a blasthole to cause pump clamping after gas is injected into an oil pumping and thermal recovery well of an oil field and when the oil pumping and heat recovery well is opened. The present invention is composed of a formula and a production method. A sand consolidating agent which is produced by the present invention has the characteristics of simple preparation and convenient construction, can consolidate powdery sand under the condition of high temperature of 360 DEG C, and can meet requirements for the high temperature thermal recovery and the consolidation of sand.
Description
A kind of be used for the gas injection of oil field oil pumping thermal recovery well after, when driving a well, prevent that silt particle from flowing into the production method that pit shaft causes the high temperature sand-fixing agent of holddown by borehole.
In the past, after oil field oil pumping thermal recovery well injected steam, under the effect of steam, some cementing matter was destroyed.When driving a well,, thereby very easily cause holddown, cause equipment to shut down because cementing matter destroyed flour sand that produces under the steam effect can flow into pit shaft by borehole.
Purpose of the present invention is a product of producing a kind of high temperature sand-fixing agent by name by a kind of specific production method.After the oil well gas injection, immediately this product is injected the stratum, make behind the flour sand and this medicament effect of immediate vicinity of wellbore, be cellular-shaped concretion state, do not hinder crude stream to go into to block under the prerequisite of pit shaft flowing of flour sand thereby be implemented in, reach the purpose that restorer runs well.
The present invention is made up of prescription and production method two portions.
It is as follows to fill a prescription:
Material name molecular formula ingredient proportion
Calcium hydroxide Ca(OH)
26-7kg
Lime carbonate CaCO
31.5-1.7kg
Kerosene 0.9-1.1kg
Tetramethoxy-silicane Si(OCH
3)
40.6-0.7kg
Hexamethyl silicon amine 0.09-0.11kg
Water H
2O 0.09-0.11kg
Tensio-active agent 2.6-3.0kg
Sodium methylene bis-naphthalene sulfonate 2.6-3.0kg
Production method is as follows:
Earlier the calcium hydroxide of 6-7 kilogram and the lime carbonate of 1.5-1.8 kilogram are dropped in the ball mill, sieve after being ground to 150 orders, send into mixing machine behind the sieve, the kerosene that adds the 0.9-1.1 kilogram then, 0.6-0.7 the tetramethoxy-silicane of kilogram, 0.09-0.11 the hexamethyl silicon amine of kilogram, 0.09-0.11 the water of kilogram, 2.6-3.0 the tensio-active agent of kilogram, 2.6-3.0 the sodium methylene bis-naphthalene sulfonate of kilogram, start to take out after mixing machine 0.5-1.5 hour and be finished product, also can be by raw material shared proportional in prescription, according to the condition of production unit, produce either large or small dose product.
The sand-fixing agent of producing with the present invention has that preparation is simple, the characteristics of easy construction, can be under 360 ℃ of pyritous conditions fixed flour sand, can satisfy the needs of the solid sand of high-temp thermal recovery.
Embodiment:
Earlier 6.48 kilograms calcium hydroxide and 1.62 kilograms lime carbonate are dropped into ball mill, sieve after being ground to 150 orders, send into mixing machine behind the sieve, add 0.9 kilogram kerosene, 0.65 kilogram tetramethoxy-silicane, 0.1 kilogram hexamethyl silicon amine, 0.1 kilogram water, 2.8 kilograms surfactant B G-01,2.8 kilograms dispersion agent sodium methylene bis-naphthalene sulfonate then, start mixing machine and mix to take out after 1 hour and get final product.
