中国石油大学（华东）毕业设计（论文）XXXXXXX学院毕业设计（论文）油井压裂防砂的工艺学生姓名：学号：专业班级：指导教师：年月日1摘要参考国内外油井防砂技术，对某油田7217井采用了树脂涂层砂防砂工艺。该技术是通过压裂泵车产生的高压对油层进行压裂造缝，提高导流能力，然后对裂缝和亏空井段挤入不同粒径、不同类型的树脂砂作为支撑剂，树脂砂在地层温度下固化形成人工井壁，达到既防止油井出砂，又提高油层导流能力的目的。目前在采油二厂共实施油井10口，累计增产原油近5000t，现场应用起到较好的防砂效果。关键词：压裂；防砂；树脂涂层砂；人工井壁2目录第1章前言································································································11.1研究目的和意义·················································································11.2研究动向·····························································································11.3研究的主要内容·················································································2第2章油层出砂原因················································································32.1油井出砂的危害·················································································32.2油井出砂的原因·················································································32.3出砂方式及判断油井出砂的标准·····················································6第3章防砂工艺························································································73.1机械防砂····························································································73.2化学防砂····························································································113.3两种防砂工艺的对比········································································14第4章压裂防砂·······················································································154.1树脂涂层砂压裂封口作用原理························································154.2室内试验····························································································154.3适用条件····························································································204.4施工及工艺参数设计········································································20第5章7217井防砂工艺的应用与分析·······················
