Sinopec News Network News In the first half of 2021, Henan Oilfield continued to strengthen a number of mature technologies such as fracturing of development wells in the old eastern area, integration of water injection well measurement and adjustment, small casing secondary cementing, and high-strength channeling and plugging of thermal recovery wells.
The cumulative oil increase was 24,000 tons
.
Aiming at the problems of poor physical properties and low natural productivity of low-permeability reservoirs in Biyang Sag of the oilfield, the oilfield has fully studied the geological characteristics of the block, the difficulty of single well reconstruction, and optimized multi-scale volume fracturing, secondary sanding fracturing, and subdivision fracturing.
And other technology, so that the effect of fracturing measures to increase production to a new level
.
Up to now, the 19 fractured wells in the east have produced a total of 4774.
3 tons of oil
At the same time, according to the serious leakage problem in the cementing process, this oilfield widely applies the small casing secondary cementing technology, and optimizes the compressive strength of the cementing plugging agent by optimizing the cementing fiber material to improve the cementing effect
.
In the first half of the year, the technology was tested on 11 wells in the field, accumulatively increasing the oil by 662.
