The utility model belongs to the field of equipment manufacturing, in particular to a multi-channel tubing and its matching joints. The utility model is characterized in that it comprises a multi-channel joint end, a multi-channel joint parent end, a multi-channel tubing body, a multi-channel tubing support plate and a sealing plate, forming a complete multi-channel tubing and its joint connection system. When the two multi-channel tubing are connected in the middle and rear of the channel, the effect of connecting the two tubing can be achieved without rotating the tubing body and only by rotating the connecting cylinder at the parent end. After the connection of the two multi-channel tubing, the sealing disc between the common end and the parent end automatically achieves the sealing effect through the sealing cone surface, so that each channel does not collude with each other, thus realizing the effect that the fluid in each channel operates in different stratum target layers. Moreover, the joint size of multi-channel tubing is the same as that of conventional tubing, and the wellhead tools of conventional tubing can also be used on multi-channel tubing.
【技术实现步骤摘要】
一种多通道油管及其配套接头
本专利技术属于装备制造领域,具体是一种多通道油管及其配套接头。
技术介绍
油管是石油钻采行业采油工程中建立目的层(油层或水层)和地面装置之间通道的重要的管柱部件,是抽油、注水以及酸化压裂等作业工序中不可或缺的。当前为实现钻井效益的最大化,往往一口井要钻开多个目的层,在后期开发时采取分隔封堵的技术进行分层开发,即一段时间内,只开发一个目的层。目前常见的标准化油管,管体本身都是单一通道,即一根管子,两端是接头,接头分为整体式的和非整体式的(即带接箍的)。用这种油管建立的地层和地表之间的单一通道,只能一次开发一个目的层,不能多层同步开发,在开发其他目的层时,也需要重新起下油管,打开目的层,而起下油管就要引进修井机进行作业,耗时耗力,引起油田作业成本的增加。专利技术创造内容申请人在长期从事机械设计与制造的工作中,经过不断探索和研究,目的在于提供一种多通道油管及其配套接头,改进目前油田在具有多个目的层的油井或水井中更换作业目的层过程中,多次使用修井机进行起下油管作业,引起作业成本增加的弊端,达到减少起下油管作业次数的目的,同时解决单一油管通道不能 ...
