胜利油田地处黄河三角洲地带,海岸线长,地形复杂,由粉砂土及粉砂质淤泥构成分层状软地基。在这样的条件下建设油田,需用大量的砂子和石料来修筑公路或加固软土地基。由于当地砂石料来源困难,运输距离又远,工程投资很大。为此,进行了用水玻璃作为主要固结材料,再添加少量醋酸乙酯(固化剂)和促凝剂,以海水为溶剂,将孤东海滩地区粉砂土化学固结的试验研究,获得了初步成
Shengli Oilfield is located in the Yellow River Delta, has a long coastline and a complex terrain. It consists of silty soil and silty mud to form a layered soft ground. Under such conditions, the construction of oil fields requires the use of large amounts of sand and stones to construct roads or reinforce soft grounds. Due to the difficulty of local sand and stone materials, the transportation distance is far away, and the project investment is very large. For this purpose, water glass was used as the main consolidation material, a small amount of ethyl acetate (curing agent) and accelerator were added, and seawater was used as the solvent to test the consolidation of silt soil in Gudong Beach area.
