Embodiment 1

[0017] Embodiment 1, the raw material of the methyl glucoside polyamine drilling fluid is calculated in parts by weight: every 100 parts by weight includes 1 to 7 parts of methyl glucoside, 0.5 to 5 parts of polyamine shale inhibitors, 0.1 to 5 parts of plugging agent, 0.5 to 5 parts of bentonite, 0.2 to 6 parts of fluid loss control agent, 0.1 to 0.5 parts of coating agent, 0.1 to 1.5 parts of flow regulator, and 0.1 to 1.5 parts of lubricant 2 parts and the remaining amount of water; wherein, the methyl glucoside polyamine drilling fluid is obtained by the following preparation method: put the required amount of bentonite into water and mix it uniformly and let it stand for 8 hours to 24 hours, then add The required amount of coating agent, fluid loss reducer, plugging agent, polyamine shale inhibitor, flow regulator, methyl glucoside, lubricant, mixing evenly to get methyl glucoside polyamine drilling liquid. Methyl glucoside polyamine drilling fluid belongs to the water-b...

Embodiment 2

[0018] Embodiment 2, the raw material of the methyl glucoside polyamine drilling fluid is calculated in parts by weight: every 100 parts by weight includes 1 part or 7 parts of methyl glucoside, 0.5 part or 5 parts of polyamine shale inhibitor, 0.1 or 5 parts of plugging agent, 0.5 or 5 parts of bentonite, 0.2 or 6 parts of fluid loss control agent, 0.1 or 0.5 parts of coating agent, 0.1 or 1.5 parts of flow regulator, 0.1 or 1 part of lubricant 2 parts and the remaining amount of water; wherein, the methyl glucoside polyamine drilling fluid is obtained by the following preparation method: put the desired amount of bentonite into water and mix it uniformly and let it stand for 4 hours or 24 hours, then add The required amount of coating agent, fluid loss reducer, plugging agent, polyamine shale inhibitor, flow regulator, methyl glucoside, lubricant, mixing evenly to get methyl glucoside polyamine drilling liquid.

Embodiment 3

[0019] Embodiment 3, the difference from the above-mentioned examples is that the methyl glucoside polyamine drilling fluid also includes 0.5 parts to 64 parts of weighting agent, wherein, the methyl glucoside polyamine drilling fluid is obtained by the following preparation method : Put the required amount of bentonite into water and mix well, then let it stand for 8 hours to 24 hours, then add the required amount of coating agent, fluid loss reducer, plugging agent, polyamine shale inhibitor, The flow regulator, methyl glucoside, lubricant and weighting agent are stirred and mixed evenly to obtain the methyl glucoside polyamine drilling fluid. When the drilling fluid is used, it is required to add different amount of weighting agent according to different drilling fluid density to adjust the drilling fluid density.

Abstract

The invention relates to the technical field of drilling fluids in petroleum drilling engineering and particularly relates to a methylglucoside polyamine drilling fluid and a preparation process thereof. The preparation process for the methylglucoside polyamine drilling fluid comprises the steps of placing a required amount of bentonite into water to be mixed uniformly, standing the mixture, adding required amounts of a coating agent, a fluid loss additive, a blocking agent, a polyamine class shale inhibitor, a flow pattern conditioning agent, methylglucoside and a lubricating agent into the mixture, and mixing uniformly to obtain the methylglucoside polyamine drilling fluid. In addition to the excellent performance of existing water-based drilling fluids, the methylglucoside polyamine drilling fluid has strong inhibition performance and good lubricating performance, and meanwhile, the methylglucoside polyamine drilling fluid has the advantages of being environmentally friendly and low in cost.

Description

technical field [0001] The invention relates to the technical field of drilling fluid in petroleum drilling engineering, and relates to a methyl glucoside polyamine drilling fluid and a preparation method thereof. Background technique [0002] Drilling fluid is a working fluid that has many functions during drilling, such as carrying and removing cuttings, cooling and lubricating the drill bit, balancing formation pressure, protecting the stability of the wellbore wall and protecting the oil layer from damage. Its performance directly affects drilling efficiency and downhole drilling. Safety and cost control are important components of drilling engineering technology. As the development of oil fields gradually enters the middle and later stages, the difficulty of drilling operations and the cost of oil and gas well development are increasing sharply. There are more and more downhole complex situations encountered in drilling. The problems often encountered include excessive...
