摘要 采用X射线衍射(XRD)、扫描电镜(SEM)、红外光谱(IR)考察了由开环聚合反应制备的聚胺处理前后蒙脱土的层间距、官能团及表面形态的变化,初步确定了聚胺抑制剂和蒙脱土的作用机理。结果表明,聚胺运动黏度为305~1940mm2/s、阳离子度为2.235~4.426mmol/g时,可实现对蒙脱土的有效束缚,可将其层间距由1.572nm缩至1.361~1.413nm范围内;在上述聚胺物性参数范围内,蒙脱土层间距与聚胺的运动黏度关系不大,与聚胺的阳离子度关系极为密切,阳离子度越大,层间距越大。聚胺能够运移至地层发生作用,通过静电引力、氢键作用、锚固作用以及疏水作用等实现对黏土的有效束缚,从而起到良好的井壁稳定效果。 By using X-ray diffraction (XRD), scanning electron microscope (SEM) and infrared spectroscopy (IR), the lattice spacing, functional group and surface morphology changes of montmorillonite pre and post treatment by polyamine prepared by ring-opening polymerization were investigated. Based on the above investigation, the shale inhibition mechanism was identified preliminarily. Results showed that, when kinetic viscosity of the polyamine shale inhibitor was in the range of 305 to 1940 mm2/s and cationic degree was in the range of 2. 235 to 4. 426 mmol/g, montmorillonite could be effectively bounded up with the lattice spacing ?educed from 1. 572 nm to the range of 1. 361-- 1. 413 nm. With the addition of polyamine shale inhibitor of above physical parameters, the lattice spacing of montmorillonite has little relation with kinetic viscosity of polyamine, but was greatly dependent on cationic degree of polyamine. The higher the cationic degree of polyamine, the higher the lattice spacing of montmorillonite. Owing to the electrostatic interaction, hydrogen bonding, anchoring effect and hydrophobic effect, polyamine could migrate to the earth formation to keep excellent borehole stability.
