Shengli Oilfield's "windowed sidetracking" makes old oilfields dead in spring

Sinopec News Network reported that the East 11-20 Well of Gudao Oil Production Plant in Shengli Oilfield was an old well.

This measure has a name called "window side drilling"

Sidetracking technology is favored by old oilfields due to its unique low-cost and practical advantages

As the oilfield enters the middle and late stages of development, casing damage or other reasons have caused imperfect well patterns and scattered remaining oil.

Most blocks of Gudao Oilfield have entered the late stage of development, and the use of sidetracking horizontal well completion technology to extract remaining oil has become an important means for them to improve development efficiency

The Hekou Oil Production Plant used window sidetracking technology to drill the abandoned well Zhan 4-Ping 22 on the basis of the abandoned well Zhan 4-Ping 22.

As of 2021, the large-diameter sidetracking completion technology has been used in Shengli Oilfield for 11 well times, with an average daily production of 24.
