Description
Technical field
The utility model belongs to field of petroleum exploitation, oil well plugging back-up sand equipment specially in petroleum secondary recovery.
Background technique
With the growth of Jiangsu oilfield, oily area most of at present enters the secondary recovery phase, oil-water well over time,
Pit shaft aging corrosion gradually increases.And the measure construction of secondary recovery phase is ordinary, working procedure gradually complicates, part aging
Pit shaft or seriously corroded or casing deformation cannot bear high pressure and tripping in packer.Certain penetrated can temporarily be blocked by filling out husky construction
Well section reaches measure construction purpose.Husky construction well is filled out at present gradually increase, and fill out husky device still many years ago, always not
It improves, there is numerous drawbacks.With the needs of social development, higher and higher, original behaviour for filling out husky device is required to operation field HSE
The practice does not meet HSE requirement, and there is an urgent need to improve to filling out husky technique and device improves.
It is the grains of sand to be transported in well by oil pipe, using carrying power of the water when pit shaft is just flowed through after a period of time
It is deposited in pit shaft, to achieve the purpose that oil-separating layer.Back-up sand protects target zone as oil-separating layer temporary in oil field development
A construction technology, be widely applied in construction, its great advantage is that polluted reservoir, negative pressure well can not established and be followed
It can not carry out playing plug in the case where ring, select back-up sand, simple to operation, construction investment is small.
It fills out hourglass bucket to connect on well head, since gaza's leak is unlimited, first manually that gaza mouthful is clogging, cementing truck is slow
The grains of sand after direct circulation is established, from manual control gaza of gaza mouthful, are transported to shaft bottom using the carrying capacity of water by shelves direct circulation.
Due to the nearly 2Mpa of the frictional resistance of pit shaft, take husky liquid pit shaft it is built-in attention recycle when, manually to block gaza mouthful has
Certain risk takes husky liquid and is not easy to establish direct circulation, does not meet the HSE requirement of job execution.
Drawback 2：Gaza mouthful is open type, and the rate of gaza wants manual control.
Drawback 3：When during filling out sand just in case causing blockages processing to be suppressed, it is necessary to connect cementing truck pipeline from new.
Drawback 4：Part well head is very high, and along with the height for filling out hourglass bucket, the labor of construction is increased when adding sand
Fatigue resistance, personnel's operation are relatively difficult.
Drawback 5：Because well site condition limits, need the sand added that cannot be transported to well head with vehicle, but manual handling leads to labor
Fatigue resistance is big.
Therefore a kind of can establish is needed to recycle gaza and manageable new device.
Summary of the invention
The utility model is mainly solving the technical problems that the bad control of speed, water sand easily cause spray during artificial plus few
Slurry.
The utility model is such solution above-mentioned technical problem：It is made of sand-filling apparatus and priming apparatus two parts,
Middle sand-filling apparatus upper end is back-up sand bucket, and back-up sand bucket lower end connects water pipe and water sand tube, and water pipe is above water sand tube, back-up sand dress
It sets and is connected by linking up with priming apparatus, control panel is installed below back-up sand bucket.
Water pipe and water sand tube opening upwards.
Back-up sand bucket upper end opening is greater than lower ending opening.
The utility model is attainable to be had the beneficial effect that：Device design is simple, facilitates installation, easy to operate, Ji Nengman
Sufficient field operation, and can guarantee construction quality；With the mixed husky ratio of baffle controls, the rate of gaza can be effectively controlled；Fill out hourglass bucket
Highly artificial controls, and reduces working strength, proposes effect；It encounters emergency case while can immediately treat, sand such as occur and block up,
Stop gaza immediately, cementing truck suppresses de-plugging；It is convenient to establish circulation, avoids filling out and manually blocks gaza before sand to establish circulation
The risk that mouth generates.
Detailed description of the invention
Attached drawing 1 is the utility model primary structure schematic diagram.
Specific embodiment
Parts title representated by each label is as follows in attached drawing：
