为解决江苏油田赵集矿区芒硝水平连通井组稳产期短、硝水质量下降的问题，根据芒硝的溶解物性和开采特点，对水平井技术套管下入位置及水平段在硝层中的位置、注水方向与强度和注油频率等涉及水平连通井组开采的几个关键技术进行了研究和试验。经过2个新井组近2年的应用，井组的硝水质量高、控盐效果好、控盐时间长，研究和设计的有效性与可靠性得到了充分的验证，可对矿区其它新井组的设计和生产提供有益的指导。

In order to solve the problems of the shorter period of stable production and the lower quality of brine in Glauber＇ s salt hor- izontally connected well pair in Zhaoji salt mine Jiangsu Oilfield, this paper carries out research and experiment on the position of technical casing setting into the layer and the position of horizontal segment in the layer of horizontal well; injection direction, strength and oil injec- tion frequency and other key technologies in horizontal connected well pair mining according to the solution features and mining charac- teristics. After 2 years application in 2 new well pairs, the brine quality is improved; salt control effect is good and salt control time is long the effect and reliability of the research and design have been testified, which provides useful guidance to the design and production of other new well pairs in the mining area.
