水平井滤饼解除技术室内研究及矿场应用
|
摘要
针对大港油田在水平井钻井过程中主要应用的钻井液体系,室内研发了GC系列钻井液滤饼解除液。该体系具有清洗效果好,溶蚀能力强,破胶能力强的特点,防膨能力、铁离子稳定能力,界面张力和腐蚀能力等辅助性能指标均优于目前在用的滤饼解除体系;并且该体系对于水平井滤饼的解除针对性强,施工简单,解除效果更好,能够疏通近井地带的渗透通道,最大限度的保护水平井的产能。矿场实验表明,该体系对于水平井滤饼解除具有良好的效果,最大程度地保护了油井的产能,保护了油气层。
According to the drilling fluid system mainly used in Dagang Oilfield horizontal well drilling,GC series of drilling fluid filter cake removal liquid was developed in the laboratory. This system has good cleaning effect,corrosion ability,characteristics of gel breaking ability,anti-swelling ability,iron ion stability,interfacial tension and corrosion resistance and other auxiliary performance. The indicators are better than the relief system used in the cake,and the system for the lifting of horizontal well cake has strong pertinence,simple construction,and better lifting effect. It can dredge the penetration of the channel near the wellbore,and the protection of the maximum capacity of horizontal well. The field experiment shows that the system has good effect on the removal of the horizontal well filter cake,which protects the productivity of the oil well and protects the oil and gas reservoir.
