摘要
地层矿物组分、理化性能分析是整个泥浆工作中一项极为重要的基础工作。在对江苏地区主要勘探开发区块地层的岩心矿物组分和理化性能分析的基础上 ,进行地层分类及地层泥浆技术及工艺的适应性研究 ,制定出富民等 32个区块的泥浆技术方案 ,解决了一些地区的垮塌问题 ,尤其是近年来在崔庄、码头庄会战中 ,大大减少复杂事故的发生 ,缩短了钻井周期、完井周期、保护了油气层。
Analysis of mineral composition,physical and chemical properties on instable formation rock in an important work in the study of drilling fluid.This paper reviews formation classification on the basis of analysis on the mineral composition,physical-chemical properties for formation rock of main regions of exploration and exploitation in Jiangsu oil field.Drilling fluid technology suitable to the formation is studied and standard design and technical schemes of drilling fluid for 32 oil fields are established.Field testing of 813 wells shows that problem of instable wellbore has been considerably improved.
