水平井分段射孔工艺在大庆油田正处于研究实践阶段,施工井数少,现场经验缺乏,在现场施工时,各环节之间的配合与衔接尚在摸索实践中,在枪身串进入防喷立管、施工中的枪串下井困难,水平段泵送压力与排量的关系,桥塞坐封与枪身串点火的操作过程中的突发情况的处理等一系列问题有待进一步研究处理。 In the field of Daqing Oilfield, horizontal well perforation process is in the stage of research and practice, with a small number of construction wells and lack of field experience. In the field construction, the cooperation and connection between various links are still being explored in practice. A series of problems need to be studied further, such as spray riser, difficulty of gun string in construction, pumping pressure and displacement in horizontal section, handling of sudden situation in bridge plug setting and gun body string ignition operation .
