随着社会生产力的不断发展,人民生活水平的提高,人们对于生活质量的要求也在不断的提高。各行各业也都在寻找着自己需要的最优质、最适合的能源。而天然气在整个过程中备受广大生产厂家企业以及生活居民的青睐。因此,天然气的开采便成为各种能源开发中的一个首要项目。但是,天然气的存在有着它自己的特殊性,在很多方面,它和传统的能源有着很大的区别。虽然,天然气和原油在地下的储存位置及各方面程度是基本保持一致的,但是,在一定条件下,它的开采和其他能源相比,有一个比较明显的特点就是受到天气等自然因素的影响比较大。除自然条件之外,前期的井下节流装置安全问题也是一个不容忽视的方面。 With the constant development of social productive forces and the improvement of people’s living standard, people’s requirements for the quality of life are constantly improving. All walks of life are also looking for the best and most suitable energy they need. The natural gas in the whole process by the majority of manufacturers and businesses of all ages and residents of all ages. Therefore, the exploitation of natural gas has become a major project in various energy development. However, the existence of natural gas has its own particularity, in many ways, it is very different from traditional energy sources. Although natural gas and crude oil are basically the same in underground storage locations and in all aspects, under certain conditions, one of the obvious features of its exploitation compared with other energy sources is that it is affected by natural factors such as weather bigger. In addition to the natural conditions, the safety of the downhole throttling device is also an aspect that can not be ignored.
