Recently, the key exploratory well Wei 457HF in the Zhongyuan Oilfield has successfully completed the drilling and coring work

Wei 457HF is an appraisal well deployed by the Zhongyuan Oilfield Company in the east wing of the Hubuzhai structure.

During the construction process, the ZY233 logging team undertook comprehensive logging tasks to actively overcome various unfavorable factors such as the lack of data from adjacent wells, high gas logging base values, continuous release of upper high pressure layers, and poor representation of cuttings caused by leakage.

According to the actual drilling situation, the well has drilled 6 cores in the lower 8 sand group of Sha 4 and the upper 3 sand group of Sha 4, with an average harvest rate of 97.

At the same time, the high-quality and efficient comprehensive logging work of the well has also been highly praised by the relevant leaders of the Oil and Gas Exploration Management Department of the Oilfield Branch
