Recently, Shengli Offshore Chengbei 6E-1 well completed the operation and opened the well
.
Chengbei 6E-1 well is located on the Chengbei 6E platform on the sea, about 15 kilometers away from the shore.
It is an oil well in the upper strata and has considerable historical production
.
The formation of this well is blocked, with bottom water in the lower layer and high shale content.
In view of the actual situation in the well, Shengli Operation No.
5 Platform of the Marine Trial Repair Engineering Department of Shengli Downhole Operation Company responsible for this construction has repeatedly demonstrated and determined that the upper layer of sandstone is acid-blocked and the lower layer is not treated to optimize the removal of plugging without drawing filtration.
The plan idea of processing radius and construction parameters is to complete the well with the electric pump according to the geological production allocation, adjust the position of the pump, and go down the well with sensors
.
Optimize production and development at the initial stage of well opening, control production pressure difference, and ensure long-term operation results
In the face of difficulties in construction, the platforms are arranged in an overall plan, rationally arranged, and construction measures are optimized
.
At the same time, strengthen quality process control during construction, strictly prevent formation leakage, strictly implement the dispatch system, and pay attention to the overall supervision of the construction operation, safety behavior, and construction evaluation of the on-site cooperative contractor, which effectively guarantees the high-quality, high-efficiency, and low-consumption completion of the well.
