Abstract

The invention relates to an oil-based drilling fluid, in particular to an organic soil activator for the oil-based drilling fluid and a preparation method thereof. The invention provides a treating agent capable of improving the slurry preparation capacity of organic soil, namely an organic soil activator. The agent is a micromolecule organic polymer with multiple functional groups, and is characterized in that: the organic soil can be dispersed and swelled into gel in white oil in a short time. Thereby improving and enhancing the gelatinizing rate and the pulping capacity of the organic soil.

Description

A kind of organoclay activator and preparation method thereof
Technical field
The present invention relates to a kind of oil base drilling fluid, particularly relate to a kind of oil base drilling fluid organoclay activator and preparation thereof Method.
Background technology
For the organoclay of oil base drilling fluid owing to the raw material soil used is different, organic modifiers is different, it is in white oil Or the yield in difference oil product differs greatly, often do not reach the viscosity needed for oil base drilling fluid and shear force requirement, for solving Certainly this problem, we have researched and developed a kind of inorganic agent organoclay activator that can improve organoclay ability with slurry. This agent is multi-functional little molecule organic polymer, is characterized in: organoclay can be made within a short period of time rapid in white oil Dispersion, swelling plastic.Thus improve plastic rate and the yield of organoclay
Summary of the invention
The invention provides a kind of oil base drilling fluid organoclay activator and preparation method thereof.
Technical scheme is as follows:
A kind of oil base drilling fluid organoclay activator, in parts by weight, contains:
20 parts of water
PEG-200 50-60 part
Polyalkylene glycol acrylate copolymer 20-30 part
The preparation method of a kind of oil base drilling fluid organoclay activator, by 20 parts of water in parts by weight, 50-60 part PEG- 200,20-30 part polyalkylene glycol acrylate copolymer mix homogeneously, with NaOH regulation pH value to 7-10, react at 70-90 DEG C 3-5 hour, prepared transparency liquid was this product.
Beneficial effects of the present invention: can make within a short period of time organoclay in white oil rapidly dispersion, swelling plastic, thus Improve plastic rate and the yield of organoclay.
Detailed description of the invention
Embodiment 1
By 20 parts of water in parts by weight, 50 parts of PEG-200,20 parts of polyalkylene glycol acrylate copolymer mix homogeneously, use NaOH regulation pH value, to 8-9, reacts 5 hours at 70 DEG C, and prepared transparency liquid is this product.
Embodiment 2
By 20 parts of water in parts by weight, 60 parts of PEG-200,30 parts of polyalkylene glycol acrylate copolymer mix homogeneously, use NaOH regulation pH value, to 8-9, reacts 5 hours at 90 DEG C, and prepared transparency liquid is this product.
Embodiment 3
By 20 parts of water in parts by weight, 50 parts of PEG-200,30 parts of polyalkylene glycol acrylate copolymer mix homogeneously, use NaOH regulation pH value, to 8-9, reacts 3 hours at 90 DEG C, and prepared transparency liquid is this product.
The performance test of product:
Table 1 adds base slurry performance after the organoclay activator of the present invention
Knowable to data, after organoclay adds activator, plastic viscosity PV and yield value YP are greatly improved, it was demonstrated that activate Agent can be effectively improved organoclay plastic rate, the beneficially full oil base drilling fluid of rapid preparing.

Claims (1)
