Saltwater drilling fluid used in the exploitation of the brine well located around Hongze and Huaiyin undertaken by Jiangsu Oil Field in recent years contains much more CT and is also abundant in K~+, Ca~(2+), SO_4~(2+) etc, so its conductivity is higher.
近年来，江苏油田承钻了位于洪泽、淮阴一带的盐井，使用盐水钻井液，该钻井液中Cl~-含量高，同时富含K~+、Ca~(2+)、SO_4~(2-)等离子，电导率大，另外其中还含有多种成分复杂的添加剂，又因井内温度较高(超过80℃)，钻井液内含有溶解氧，因而对钻具的腐蚀很严重。
补充资料：盐水钻井液
分子式：
CAS号：
性质：又称盐水泥浆。含盐(NaCl)1％以上(氯离子含量在6000～189 000mg/L)的钻井液。其中含有较多的无机盐，需采用一些耐盐的处理剂如凹凸棒石、海泡石、淀粉、黄原胶、瓜尔胶等来维持其黏度和井眼清洁性质。
