摘要:
顺北油田目前存在较严重的沥青质析出及堵塞现象,影响了油气井的正常生产。通过正庚烷沉淀法提取纯化沥青质后,利用傅里叶红外光谱、元素分析和核磁共振氢谱对沥青质的化学结构进行研究,使用飞行时间质谱对其重均分子量进行测量,最后推算得到沥青质的分子结构式,为研究沥青质的析出沉淀规律奠定理论基础。此外,借助油藏数值模拟软件对沥青质在高温高压下的析出沉淀规律进行了研究,绘制了沥青质的析出曲线和包络线图。最终,根据生产现场的井筒温压条件,得到了顺北原油在生产条件下的析出沉淀规律。
Abstract:
The Shunbei Oilfield currently has serious asphaltene precipitation and blockage,which has affected the normal production of oil and gas wells.After the extraction and purification of asphaltenes by n-heptane precipitation method,the chemical structure of the asphaltenes is studied by Fourier infrared spectrum,elemental analysis,and 1H NMR. And then the weight average molecular weight is measured by time-of-flight mass spectrometry.Finally,the molecular structure formula of asphaltenes is calculated,which lays a theoretical foundation for studying the precipitation rules of asphaltenes.In addition,the precipitation law of asphaltenes under high temperature and high pressure is studied by using reservoir numerical simulation software,CMG,and it is drawn the precipitation curve and envelope diagram of asphaltenes.Finally,according to the wellbore temperature and pressure conditions,it is obtained the precipitation law of Shunbei crude oil under production conditions.
