Anti-cracking drilling fluid rock debris curing agent and use method thereof
The invention provides an anti-cracking drilling fluid rock debris curing agent. The curing agent comprises the following materials: slag powder, desulfurized gypsum, beta-hemihydrate gypsum, fly ash,construction waste powder, sylvite or ammonium salt, an excitant and an organic heavy metal chelating agent. According to the anti-cracking drilling fluid rock debris curing agent and the using method, the curing agent is added into the target rock debris, so that the chemical oxygen demand (COD), the pH value, the chromaticity and petroleum substances in the rock debris are all improved. The curing strength of the rock debris is improved by 6-9 times, high-cost materials such as cement do not need to be added, the rock debris can be prevented from cracking after being cured, and the method is an environment-friendly and low-cost curing technology.
本发明提供的一种防开裂钻井液岩屑固化剂，所述固化剂含有如下材料：矿渣粉、脱硫石膏、β型半水石膏、粉煤灰、建筑垃圾粉末、钾盐或者铵盐、激发剂和有机重金属螯合剂。本发明提供的一种防开裂钻井液岩屑固化剂和使用方法，在目标岩屑中加入固化剂，使得岩屑中化学需氧量(COD)、pH值、色度、石油类物质都有所改善。岩屑的固化类强度得到6‑9倍提升，而且不需要添加水泥等高成本材料，可以防止固化后岩屑产生裂缝，是一种环保且成本较低的固化技术。
