Since entering the high water cut period, the fracturing of oil reservoirs is an important measure to improve the oil production effect of oil extraction wells and also causes the sand production of the oil layer to increase. However, the technology of no sand production can "prevent sand". Pump-free production is the tubing as a pump cylinder, a number of liquid as a plunger, through the rod-type liquid in the reciprocating motion within the tubing to achieve a lift column of liquid a process. It does not need to use the pump, greatly reducing the "card pump" phenomenon occurs, it is also very easy to maintain. And when replacing the liquid lift without starting the tubing, as long as the oil rod can be replaced, greatly reducing operating costs. The liquid is also relatively short, plasticity, can adapt to different sizes of sand. In the case of downtime, the reservoir can be left in the column of liquid column is divided into small pieces, so that sand can not be concentrated in the bottom of the tube, effectively preventing the "card pump." In inclined shaft application, the liquid receiver can play the role of centralizer to prevent eccentric wear. This also reduces stroke wear resistance due to excessive centralizers. In the first half of this year, the plant conducted a pump-less pumping test on two pumping wells and two wells produced 15 tons of oil per day.
Cabinet Air Conditioner, also called enclosure air conditioner, panel air conditioner, belongs to industrial cooling equipment. It is specially used for electrical boxes to cool the electrical parts which emit large of heating, so to provide low temperature and low humidity environment inside the electrical boxes, and isolate the outside dust or corrosive gas.

At present, sands in oil reservoirs often easily lead to "stuck" pumping wells. In order to ensure the pumping unit normal "spit oil", Daqing Oilfield six production plant for the first time the use of pumping wells without pumping oil production technology, and the effect is good.
