Recently, North China Oil and Gas Branch Company's Dongsheng Gas Field Jin 30 well block He 1 section productivity construction well J30-4-P9 tested a high-yield gas flow of 182,800 cubic meters per day, setting a record for Dongsheng Gas Field Jin 30.
The horizontal wells in the well area have unimpeded new highs, further confirming the good development potential of the He 1 Member in this area
.

Aiming at the lithologic gas reservoir of the He 1 Member with strong gas heterogeneity in the Jin 30 well block of Dongsheng Gas Field, the scientific and technological personnel of the Institute deepened the sedimentary understanding, strengthened the integrated research of geology and geophysical prospecting, and summarized 8 kinds of sand body spatial superimposition.
Types, and clarify the seismic response modes of different sand body superimposed types
.

On the basis of fine seismic calibration and interpretation, using isochronous stratigraphic slicing technology based on spatial relative resolution, the distribution characteristics of three small-layer channels in the He 1 gas reservoir are finely depicted, and combined with the gas-bearing prediction results, the gas layer is clarified.

Based on the integrated research work of geology and geophysical prospecting, the No.
4 channel of the He 1 gas reservoir in this area is selected as a favorable target area.
Differentiated deployment and mixed well type development are carried out according to the sand body superimposition and gas layer development characteristics
.

A batch of well positions such as J30-4-P9 were deployed and designed.
