Low-Hygroscopic Plasticized Plugging Cement (Nizkogigroskopichnyi Plastifitsirovannyi Tamponazhnyi Tsement)
A new high-quality plugging cement was developed for use in oil prospecting developmental work in Siberia. The good storage properties and wettability of this cement were obtained by adding monoethanolamine during milling. The paper discusses the properties needed in the new cement, developmental test methods, and results leading to the choice of monoethanolamine as the most effective additive for cold or hot drill holes at the recommended rate of 0.5 to 1%, by weight of cement. Slag-portland cement (40% slag) with admixtures of 1% NaCl and 0.5% monoethanolamine during milling kept a higher strength and flowability in spite of the NaCl content (added to raise the hygroscopic properties).
