Embodiment 1

[0027] Embodiment 1. Preparation of oxidizing agent

[0028] Oxidant formulation of the present invention: in parts by weight, 30-50 parts of active agent, 5-15 parts of dicalcium hydrogen phosphate, 5-15 parts of sodium pyrophosphite, 5-15 parts of methylene dithiocyanate, 20-40 parts water.

[0029] For evaluating the performance of oxidizing agent of the present invention, prepare respectively following No. 1-3 oxidizing agent:

[0030] No. 1 oxidizing agent: in parts by weight, 30 parts of active agent, 15 parts of dicalcium hydrogen phosphate, 5 parts of sodium pyrophosphite, 15 parts of methylene dithiocyanate, and 20 parts of water.

[0031] No. 2 oxidizing agent: in parts by weight, 50 parts of active agent, 10 parts of dicalcium hydrogen phosphate, 10 parts of sodium pyrophosphite, 5 parts of methylene dithiocyanate, and 25 parts of water.

[0032] No. 3 oxidizing agent: in parts by weight, 40 parts of active agent, 5 parts of dicalcium hydrogen phosphate, 15 parts ...

Embodiment 2

[0041] Embodiment 2. Water Solubility Evaluation of Oxidizing Agent

[0042] Detect the water-solubility of oxidant of the present invention according to following method: get 3 glass beakers, each beaker adorns 100ml water, add No. , Shake well and let it stand at room temperature for 5 minutes to observe the dissolution of the oxidant. The results are shown in Table 1, and No. 1-3 oxidants have good water solubility.

Embodiment 3

[0045] Embodiment 3. Effect evaluation of oxidizing agent

[0046] Use No. 1-3 oxidants prepared in Example 1 to treat drilling waste solid water-based mud, and evaluate the oxidation effect. The low-concentration solid water-based mud waste used in this experiment was taken from an oilfield in Wuqia County, Xinjiang, and the high-concentration sulfonated water-based mud waste used was taken from the Tarim Oilfield in Xinjiang.

[0047] The mud treatment method is: take a certain amount of waste solid water-based mud, put it into a beaker after weighing, add 3% to 10% of the total weight of the mud solid oxidizer, stir evenly, so that the oxidant and mud are fully mixed, and keep the mud in the mud. The water content of the beaker is above 30% (the method of maintaining the water content is sealing: after mixing the oxidant and water-based mud evenly, wrap or cover the mouth of the beaker with plastic wrap or a sealed bag with the same size as the mouth of the beaker, and then...

Abstract

The invention relates to treatment of drilling waste solid water-based mud, in particular to an oxidizing agent for harmless treatment of drilling waste solid water-based mud, and preparation method and application thereof. The oxidizing agent is prepared from the following components in parts by weight: 30 to 50 parts of active agent, 5 to 15 parts of dicalcium phosphate, 5 to 15 parts of sodiumpyrophosphate, 5 to 15 parts of methylene dithiocyanate and 20 to 40 parts of water. The oxidizing agent has good water solubility and strong oxidizing effect, can thoroughly decompose organic mattersin the waste solid water-based mud into inorganic matters, and effectively protects the environment.

Description

technical field [0001] The invention relates to the treatment of waste drilling solid water-based mud, in particular to an oxidant for harmless treatment of drilling waste solid water-based mud, its preparation method and application. Background technique [0002] Waste drilling mud is one of the major pollutants in the petroleum industry. According to statistics, when drilling an ordinary oil and gas well with a depth of 3000-4000m, nearly 300 cubic meters of drilling mud will be discarded after completion. According to the survey results of oil pollution sources conducted by China National Petroleum Corporation in 2008, the waste drilling mud produced by drilling in my country's oil fields is about 12 million tons every year, of which 1 / 2 is directly discharged into the surrounding environment. In recent years, countries all over the world have been forced by the demand for energy, which has led to an increasing number of drilling mud types, as well as an increasing numbe...
