高温高压油井完井管柱及其密封件设计研究
|
摘要
目前埋藏较深难以动用的深井油藏逐渐成为胜利油田可采储量的重要增长点。为了沿用原有的技术成熟的采油工艺和工具,必须解决这些工艺、工具在深井的不利条件影响下普遍存在的工作性能不稳定、有效期短等问题,以完善并提高井下工艺管柱性能,相应进行了深井油井完井管柱和密封件的设计研究。
研究中最关键的部件是密封件。密封件承受压差能力的高低不仅取决于压载的大小,同时还受密封结构形状的影响,通过大变形超弹性材料的计算方法,利用ANSYS有限元分析软件模拟了胶筒的受力和变形状态,确定了相应的密封结构和坐封载荷。
设计计算共包含三部分,一是井下管柱受力分析计算;二是高压差密封胶筒有限元计算;三是井下配套工具设计计算。井下管柱受力分析计算着重分析管柱在承受井下深井时的受力,以此设计油管组成和封隔器坐封载荷;通过高压差密封胶筒有限元计算,分析各种密封结构在承受高压差时的应力分布及在不同压载条件下能承受的最高限压;井下配套工具设计计算依据井下工作条件,进行各工具关键零部件的强度校核。
深井油井完井管柱和密封件的试验研究过程通过室内实验和现场试验等途径研究密封件密封机理,优选密封件材料,优化结构,同时研制具有高承压能力的配套井下工具,完善井下工艺管柱性能,提高管柱可靠性,达到满足深井油藏经济开发的要求。该课题的研究成功大大提高了深井施工的一次成功率,延长了油井免修期,减少了施工成本,具有很好的经济效益和社会效益。
Presently rather deeply and difficultly employed oil reservoirs have gradually become important spot of recoverable reserves of shengli oil field. For the sake of well-rounded oil extraction technics and tools, we should settle instability and time-short of these techs and tools at disadvantage effect in deep well and consummate capability of pipe strings. The deep-well pipe strings and airproof piece also designed and studied in the paper.
The pivotal parts of the deep-well pipe strings and airproof tests is airproof piece. The press difference ability of airproof piece rest with load and airproof structure and shape. The paper ascertained corresponding airproof structure and load with calculate method and ANSYS finity analyse software.
There are three parts in design and calculation: one is strength analysis of well pipe string; one is finite calculation of airproof glue bamboo; another is design and calculation of mate tools. The strength analysis of well pipe string is got across by the load of the pipe string and packer load with ANSYS finity analyse software. The airproof glue bamboo is finitited with ANSYS. The other mate tools are calculate with intensity check and dependability.
Deep well pipe string and airproof piece are tested at examnination room and locale and so on to study the airproof mechanism. In order to satisfy deep oil reserveoir, we choose excellent materiall and optimize structure and develop mate downwell tools and consummate well pipe strings and improve pipe string reliability. The succed of the item has greatly improved local construct succeed probability and longer used-time and shorter cost and have good economy benefit.
