preparation example Construction

[0025] The present invention also provides a method for preparing a power source for oilfield bridge plug sealing, the method comprising the following steps:

[0026] Step 1: weighing bisphenol A diglycidyl ether type epoxy resin, oxidant, curing agent, diluent and combustion regulator according to the proportion;

[0027] Step 2: After weighing, each component is put into a mixer and mixed, and the mixing time is 40 minutes to 60 minutes to obtain a slurry;

[0028] Step 3: After mixing evenly, vacuum pour the slurry into the mold, and then solidify at room temperature for 48 hours.

Embodiment 1

[0031] This example provides a power source for oil field bridge plug sealing, which includes the following raw materials in parts by weight: bisphenol A diglycidyl ether type epoxy resin E-44: 50 parts, oxidant sodium nitrate: 70 parts , curing agent diaminodiphenylmethane: 10 parts, diluent 1,4-butanediol diglycidyl ether: 5 parts and combustion regulator ferric oxide: 2 parts. The preparation method of the power source for oil field bridge plug seat sealing comprises the following steps:

[0032] Step 1: weighing bisphenol A diglycidyl ether type epoxy resin, oxidant, curing agent, diluent and combustion regulator according to the proportion;

[0033] Step 2: After weighing, each component is put into a mixer and mixed, and the mixing time is 40 minutes to 60 minutes to obtain a slurry;

[0034] Step 3: After mixing evenly, vacuum pour the slurry into the mold, and then solidify at room temperature for 48 hours.

Embodiment 2

[0036] This embodiment provides a power source for oilfield bridge plug seating. The difference between this embodiment and Embodiment 1 is that, in parts by weight, the following raw materials are included: bisphenol A diglycidyl ether type epoxy resin E- 42: 50 parts, oxidant sodium nitrate: 40 parts, curing agent diaminodiphenylmethane: 3.5 parts, thinner 1,4-butanediol diglycidyl ether: 5 parts and combustion regulator copper oxide: 1.5 parts. Its preparation method is identical with embodiment 1.

Abstract

The invention discloses a power source for oilfield bridge plug setting and a preparation method thereof. The power source comprises the following raw materials in parts by weight: 30-50 parts of bisphenol A diglycidyl ether type epoxy resin, 40-70 parts of oxidant, 3-10 parts of curing agent, 1-5 parts of diluent and 0.5-2 parts of combustion regulator. The prepared power source does not belong to explosives and is good in heat resistance and is resistant to high temperature of 180 DEG C for 48 hours and is non-combustible and non-explosive and can meet the use requirements of deep wells andoil fields; the formula is few in components, good in compatibility, simple and feasible in process and stable in production process, and long-term storage is guaranteed and no chemical action occursat high temperature and high pressure; and the raw materials are wide in source, cheap and low in production cost.

Description

technical field [0001] The invention relates to a power source of an oil well bridge plug insertion tool, in particular to a power source for oil field bridge plug seat sealing and a preparation method thereof. Background technique [0002] The bridge plug power source is equipped with oil well bridge plug delivery tools. In recent years, with the improvement of oil well technology, higher requirements have been put forward for the bridge plug power source: low burning rate, which can reduce the erosion and burning of the bridge plug delivery tool by gas. Corrosion; low residue content, clean gas, which can ensure the smoothness of the center hole of the piston rod of the bridge plug delivery tool, and is environmentally friendly. [0003] Among most power sources at present, the butylated hydroxy-ammonium perchlorate formula system is the most widely used. Although it has a high energy level and specific impulse, the cost price is high, the production safety and environment...
