Sinopec News Network News Since this year, the Zhuangxi operation area of the Shengli Oilfield Downhole Operation Center has faced the dilemma that the Zhuangxi Oil Production Plant has no new wells and the output of the old oilfield has fallen.
Well Zhuang 106-24-Incline 12 is a low-yield and low-efficiency well with large inclination and serious sand production.
The operation area cooperates with all-round and three-dimensional adjustments of the water wells.
The Zhuang 1 oil reservoir is a side-bottom water reservoir with sufficient formation energy, but the difficulty is that the water content is too high.
The Zhuang 139 block has changed from thermal recovery to a combination of viscosity reduction and cold recovery, microbial huff and puff and microbial flooding.
