随着钻井技术的不断发展,传统直井钻井技术已经很难满足我国石油开采的现状。经过几代石油人不懈的努力,定向井技术不断的更新,形成了一套成熟的、完善的、实践与理论相结合的开采技术。事实上,过去的直井技术在实践应用过程中针对层段开发难以发挥应有的作用,而定向钻井技术以其独特的优势在石油开采过程中扮演者十分重要的角色。定向井钻井方法的运用一方面可以确保井眼轨迹的准确性,另一方面对提升开采工作效率也具有积极的意义。而上述目标的实现必须对过去的钻具组合进行科学的、合理的改进,以满足开发地层的需求,提升钻进工作效率。
With the continuous development of drilling technology, the traditional vertical well drilling technology has been difficult to meet the current situation of China’s oil exploration. After several generations of oil people make unremitting efforts, directional well technology constantly updated, formed a set of mature, perfect, practice and theory of combining mining technology. In fact, the past vertical well technology was hard to play a proper role in the practical application process for the development of layers, and directional drilling technology played a very important role in the oil extraction process due to its unique advantages. The application of directional well drilling method can ensure the accuracy of borehole trajectory on the one hand, and also has positive significance on improving mining efficiency. The above objectives must be scientifically and reasonably improved on the past drilling assembly in order to meet the demand of stratigraphic development and enhance the efficiency of drilling work.
