D井高温高密度钻井液体系优化研究

Optimization of high temperature and high density drilling fluid system in D well

随着油气资源勘探的不断深入,钻探的难度越来越大,尤其是高温、高压、高密度井越来越对,对钻井液性能的稳定是个十分严峻的挑战。本文通过对D井钻井液性能的难点进行了分析,重点通过红外光谱分析,热失重分析,分子量测定,抗温性能评价等确定了该区块的钻井液体系,对于该区块的钻探开发具有十分重要的意义。

With the deepening of the oil and gas exploration,the difficulty of the drilling is more and more big, especially in high temperature and high pressure, high density well for more and more ,for the stability of the drilling fluid performance is a very serious challenge.This article through to D well the difficulties of drilling fluid performance is analyzed,mainly by infrared spectrum analysis,thermo-gravimetric analysis,determination of molecular weight, temperature resistance evaluation to determine the block system of drilling fluid, drilling for this block, development is of great significance.
