【摘要】：本文的研究工作主要依托于长庆油田的“低压低产气井排水采气配套工具及工艺技术研究”项目,针对在低压低产气井采用喷射排水采气工艺,常规悬挂器在下入内径Φ62mm的油管后,投放密封球时容易产生投球不到位,无法实现完全坐封,且不能承载质量较大的喷射泵。在原有悬挂器结构的基础上进行改进创新,设计出可取式压差作用密封悬挂器。本文主要研究内容如下:(1)通过对现有常规悬挂器及投送器的文献查阅及现场调研,根据悬挂器的功能和结构特点,进行改进创新,完成总体方案设计,分析了新型悬挂器的结构组成及工作原理,并对关键零部件进行设计计算选型。(2)利用Autodesk inventor三维建模软件对可取式压差作用密封悬挂器进行三维虚拟建模,形成了三维虚拟装配,并进行模拟运动仿真,为后续实际产品的生产加工及装配提供重要的理论参考。(3)根据低压低产气井中采用喷射排水采气工艺时的实际工况参数,在不同的工作参数条件(压力、摩擦系数)下,利用ANSYS有限元分析软件对悬挂器的卡瓦和胶筒进行数值模拟分析,得到压力、应力、结构形状尺寸等之间的相互关系,有利于进一步指导可取式压差作用密封悬挂器的结构参数设计,为今后的悬挂投送器的研制和改进提供参考。
[Abstract]:The research work of this paper is mainly based on the project of "study on drainage Gas production tools and Technology Technology of low pressure and low production Gas Wells" in Changqing Oilfield, aiming at adopting jet drainage gas recovery technology in low pressure and low production gas wells. After the conventional suspension enters the tubing with diameter 桅 62mm, it is easy to throw the ball out of place when the sealing ball is dropped, so it is impossible to realize the complete seal. And the jet pump with high quality can not be loaded. On the basis of the original structure of the suspension, it is improved and innovated. In this paper, the main research contents are as follows: 1) based on the literature review and field investigation of the existing conventional suspenders and emitters, according to the function and structural characteristics of the suspenders. To improve and innovate, complete the overall scheme design, analysis of the structure of the new suspension and working principle. And the key parts are designed and calculated. 2) using Autodesk inventor 3D modeling software to carry out 3D virtual modeling of the desirable pressure differential action seal suspension. The 3D virtual assembly is formed and simulated motion simulation is carried out. To provide an important theoretical reference for the subsequent production, processing and assembly of actual products. According to the actual operating conditions parameters (pressure) when adopting jet drainage gas production technology in low pressure and low production gas wells. Under the friction coefficient), the ANSYS finite element analysis software is used to simulate the slips and the rubber cylinder of the suspension, and the relationship among the pressure, stress, structure shape and size is obtained. It is helpful to further guide the design of structural parameters of the desired pressure differential effect seal suspension, and provide reference for the development and improvement of the suspension emitter in the future.
