Coalbed gas rodless oil extraction solving plan
According to the following central oilfield issues in mid-late period development, such as the lowed liquid level, the pumping unit loading increased caused by the dump hang deepening, the travel damage increased, and the rod tube partial wear, our company research the new type of rodless waterpower oil extraction device.
This device adopts the ball valve changing position, the long travel, and the less travel time. The SC38-74-4.8 type of rodless waterpower oil extraction device connect with the regular tube type of oil extraction pump at the onsite experiment, the lower pump depth is 1650M, the travel is 4.8M, the travel time is 2.7min, the daily water injection is 72 M ³ and the output liquid is 60 M³.
The result indicate that the new type of the waterpower oil extraction device prolong the oil well pump working time, eradicate the rod tube partial wear, and it adopt the ball valve changing position which has the less requirement for the power fluid. Meantime the daily maintain is simple.
1. The new type of the rodless waterpower oil extraction device is installed by one time, the operation is simple.
2. The new type of the rodless waterpower oil extraction device has the long travel, less travel time; that prolong the oil well pump working time and promote the pump effect.
3. The new type of the rodless waterpower oil extraction device eradicate the rod tube partial wear, especially has the obvious effect in shallow well extraction
4. The new type of the rodless waterpower oil extraction device has the slower up-travel and the faster down-travel, it fully take advantage of the power energy.
5. The new type of the rodless waterpower oil extraction device adopts the non-rubber seal components that can pour hot water and extract for the long time.
6. This device no need to discharge the sucker rod, no need to adjust the anti-clash distance and no need to adjust the rodless sealer, that reduce the workload.
7. This device adopts the ball valve changing position which has the fewer requirements for the power fluid; the daily maintain is simple.
