大庆油田是当前我国最大的一个油田,整体面积大约有6000平方公里,有40多个不同规模的油气田组成,探测范围广泛,地形条件也极为复杂,在登记的探测区域中就有十四个盆地地形。本文以大庆油田自主研发的深层水基钻井液体系为例,分析钻井液体系的性能以及在钻井过程中的具体应用。 Daqing Oilfield is currently the largest oilfield in China with a total area of ​​6,000 square kilometers and over 40 oil and gas fields of various sizes. The detection range is wide and terrain conditions are extremely complicated. Among the registered exploration areas, there are 14 basins terrain. In this paper, a deepwater drilling fluid system independently developed by Daqing Oilfield is taken as an example to analyze the performance of drilling fluid system and its application in drilling process.
