The invention relates to the field of well cluster field development in oil and gas field development, and discloses two well cluster field oil testing and well completion construction processes according to different working conditions. The first process is realized based on a set of continuous oil pipe operation machine, two sets of workover rigs and a set of ground flow. The continuous oil pipeoperation machine sequentially completes wellbore preparation operation on all small well groups in the mode that three wells form one group, and the two workover rigs are carried up in sequence andjointly complete perforation completion operation of all the wells. The second process is realized based on a set of continuous oil pipe operation machine, a set of workover rig and a set of ground flow. The continuous oil pipe operation machine performs early-stage operation on each well, and the workover rig performs well completion tubular column descending operation on each well along with theoperation track of the con
