    • An apparatus for pumping fluid, the apparatus including a pump housing including a plunger connected to a terminal end of a coiled tubing and a first port. The apparatus further including the plunger configured to move longitudinally upward and downward, wherein the plunger includes a second port and a surface pumping unit configured to modulate between two modes, a first mode configured to limit a stroke length of the plunger so that the first and second ports do not engage, and a second mode wherein the first and second ports engage. Also, a method for pumping fluid into a wellbore using an apparatus, the method comprising inserting a housing including a coiled tubing and a plunger into the wellbore, wherein the plunger is located at a terminal end of the coiled tubing, and wherein the housing includes a first port and a plunger includes a second port. The method further including moving the plunger longitudinally upward and downward within the housing wherein a stroke length of the plunger is limited during the moving the plunger and extracting fluid from the wellbore. The method further including extracting fluid from the wellbore, pulling the plunger longitudinally upward until the first and second ports are aligned, and circulating fluid into the wellbore through the coiled rubbing and first and second ports discharging into an annulus of the wellbore.
    • 一种用于泵送流体的装置,该装置包括泵壳体,该泵壳体包括连接到连续油管的末端的柱塞和第一端口。 该装置还包括被配置为纵向向上和向下移动的柱塞,其中柱塞包括构造成在两种模式之间调制的第二端口和表面泵送单元,第一模式被配置为限制柱塞的行程长度,使得第一和 第二端口不接合,并且第二模式,其中第一和第二端口接合。 另外,使用装置将流体泵送到井眼中的方法,所述方法包括将包括盘管和柱塞的壳体插入所述井孔中,其中所述柱塞位于所述连续油管的终端,并且其中所述壳体包括 第一端口和柱塞包括第二端口。 该方法还包括在壳体内纵向向上和向下移动柱塞,其中在活塞移动柱塞并从井筒中提取流体期间柱塞的行程长度被限制。 该方法还包括从井筒中提取流体,纵向向上拉动柱塞,直到第一和第二端口对准,并且通过螺旋摩擦将循环流体循环到井筒中,并将第一和第二端口排放到井眼的环形空间中。
