罗玛拉雷特气田位于纽奎盆地,是南美最重要的气田之一。在过去的10年中,储层压力逐级递减,使得该气田的运行模式从高压转变为中压,最近又转为低压生产。由于储层压力衰竭、气流速度持续减小,井筒积液等问题日益严重,为解决这一问题,引进了一种新型的小直径管柱系统。由于它在下入理想深度的情况下,可加注化学药剂,还能使用一些诸如存储仪之类的特殊设备,因而备受青睐,现场试验结果也证实其具有良好的应用前景。文章总结了最初一年内在罗玛拉雷特气田利用小直径管进行生产优化的试验结果,该结果证实,它不仅能解决生产问题,还能带来不错的经济效益。 Located in the Newquay Basin, the Romalaret gas field is one of the most important gas fields in South America. Over the past 10 years, the gradual decrease in reservoir pressure has shifted the operation mode of the gas field from high pressure to medium pressure and recently to low pressure production. Due to the depletion of reservoir pressure, the continuous decrease of gas velocity and the increasing of wellbore fluid, a new type of small-diameter pipe string system was introduced to solve this problem. Because of its depth into the next case, can be filled with chemicals, but also the use of some special devices such as memory devices and therefore favored field test results also confirmed its good prospects. The article summarizes the results of a trial of production optimization using a small diameter tube at the Romalareite gas field during the first year of the year, which confirms that it not only solves production problems but also provides good economic benefits.
