Embodiment 1

[0028] Example 1 Log the 5-year-old shaving Phoebe wood felled in Chaling County, Zhuzhou City, wash and remove impurities with a high-pressure water pump, and then use a drum planer to plan into flakes with a length of 20-50mm. The above-mentioned shavings The small pieces of Phoebe wood are transported to a low-temperature drying kiln for 8 hours at 20°C to reduce the moisture content to 6%, and then finely pulverized by a temperature-controlled wood flour machine at 50°C and passed through a sieve with an aperture of 0.180mm , remove crude fiber, get shavings Phoebe plant glue; It is dropped into blender with bentonite, sodium carbonate, polyacrylamide, carboxymethyl cellulose by 70%: 10%: 10%: 5%: 5% by weight percentage, stirs After 30 minutes until uniformly mixed, the vegetable gum drilling fluid treatment agent is obtained, which is packaged into a finished product of 25 kg / bag, and stored in a dry room temperature. The results of performance parameter testing of the v...

Embodiment 2

[0029] Example 2 The difference from Example 1 is that the shaving Phoebe wood is 8 years old, dried at 30°C for 7 hours to reduce its moisture content to 7%, and then finely crushed at 40°C and passed through a pore diameter of 0.160mm. Sieve, the content of each component is shown in Table 1 below, and stir for 25 minutes until the mixture is uniform. The results of performance parameter testing are shown in Table 1 below.

Embodiment 3

[0030] Example 3 The difference from Example 1 is that the shaving Phoebe wood is more than 10 years old and dried at 40°C for 6 hours to reduce its moisture content to 8%. mm sieve, the content of each component is shown in Table 1 below, and stirred for 20 minutes until the mixture is uniform. The results of performance parameter testing are shown in Table 1 below.

Abstract

The invention discloses a gelatine drilling fluid additive and a preparation method thereof. The preparation method comprises the following steps of: performing the procedures of washing for removing impurities, flaking, drying, fine crushing and crude fiver removal on shaved nanmu materials, thus obtaining shaved nanmu gelatine; and then uniformly stirring and mixing the shaved nanmu gelatine with bentonite, sodium carbonate, polyacrylamide and carboxymethyl cellulose, thus obtaining the gelatine drilling fluid additive. The main material, namely the shaved nanmu gelatine, of the gelatine drilling fluid additive is easy to get, and thus the gelatine drilling fluid additive has good industrialization prospect, and can replace macro guar gum drilling fluid additives at present. When being applied to the field of drilling engineering, the gelatine drilling fluid additive provided by the invention is strong in inhibiting capability, good in de-filtration effect and excellent in lubricating performance, has the characteristics of being green, environment-friendly and reproducible, and has broad development and utilization prospect.

Description

technical field [0001] The invention relates to a vegetable gum drilling fluid treatment agent and a preparation method thereof. Background technique [0002] In drilling engineering, accidents caused by the failure of drilling fluid wall plugging occur frequently, especially in the exploration of metal, coal, oil, and natural gas deposits. Therefore, drilling fluid technology is a key link in drilling engineering. With the gradual increase of drilling depth and difficulty, this technology plays an increasingly important role in ensuring safe, high-quality and fast drilling. Drilling fluid treatment agent is a chemical additive used to improve and stabilize the performance of drilling fluid, or to meet certain needs of drilling. It is the core component of drilling fluid, and often a small amount can greatly improve the performance of drilling fluid. big impact. [0003] At present, in oil drilling engineering, the patented guar gum submitted by the American Atlantic Oil R...
