查询词典 string out

Firstly, this paper researched the mechanism of tubing string vibration when natural gas flows in horizontal well tubing string. Secondly, established whole tubing string undamped and damped vibration system model according as reasonable assumption data of one horizontal well. Apply finite element analysis software to calculate tubing string natural characters, simple harmonic dynamic behavior of stable gas production and nonlinear dynamic behavior. Finally, this paper carried out the safety varied frequency of gas well and the method of vibration reduction.

本文首先从理论和数值模拟研究了天然气在水平井油管柱内的流动诱发油管柱振动的机理，然后在合理假设的基础上结合某水平井数据建立了全井段油管柱无阻尼和有阻尼振动系统模型，利用有限元软件计算分析了油管柱固有特性、稳产简谐动力学响应和非线性动力学响应，针对油管柱振动规律提出了天然气安全调节频率范围和减振措施。

显然，属性被声明为string(hey，它毕竟存在一个文本文件里)，所以它映射的类型不是string，它必须在调用property setter之前，找方法怎么把给出的string转化为正确的类型。

Aiming at the frequent occurrence of drill-string fracture during gas drilling in the Puguang gas field, this paper, based on the statistical analysis of accidents on fields, makes in-depth investigation into the origins of drill-string accidents in aspects of peculiar drilling medium, different rock-breaking methods, and the vibration of drill string during the drilling process. Through macro, micro and material analysis of the fracture surface of drill string, the law of drill-string failure due to fracture is discovered and the fatigue fracture is found out to be the main type of drill-string fracture.

针对普光气田气体钻井过程中存在的钻具断裂频繁的问题，在对现场事故统计分析的基础上，从特殊的钻井介质、不同的破岩方式以及钻井过程中钻柱共振等方面定性分析了钻具断裂的原因；通过对钻具断口宏观、微观及材质分析，找到了钻具断裂失效的规律和主要形式－疲劳断裂。
