The utility model provides a fill and prevent spouting neglected loading and put, opens passageway insertion pipe machine structure lower part and is equipped with locking sealing mechanism including opening passageway insertion pipe machine structure, and locking sealing mechanism lower part is equipped with stratum passageway on -off mechanism, and stratum passageway on -off mechanism lower part is equipped with to prevent spouting leaks the mechanism, prevents spouting hourglass mechanism lower part and is equipped with packing tool docking mechanism, and the oil recovery insertion pipe machine who still is equipped with and opens passageway insertion pipe machine structure interchangeable in addition constructs. The utility model discloses to open passageway insertion pipe machine and construct, locking sealing mechanism, stratum passageway on -off mechanism prevents spouting and leaks the mechanism, and packing tool docking mechanism constructs with oil recovery insertion pipe machine and organically combines be in the same place, has solved when examining the pump operation flushing fluid and has easily missed and recharge the stratum, and the back pressure oil reservoir leads to the fact the stratum to supply that liquid is not enough, flushing fluid misses seriously, and the well -flushing is difficult to successfully, leads to the fact the problem of blowout occurence of failure easily. Improved the operation success rate, shown and practicing thrift the operating cost.
