Abstract: To adjust and tap the potential of maturing tracts of Jidong oil field, we carried on the accurate reservoir description to meet the needs of the oil field. The basic points are:multi-disciplinary description while geology plays a leading role, correcting (or reconstructing) the sand-grid model,interpreting the microscopicstructure of the oil-bearing formation's top surface accurately, descripting the plane distribution of the sandstone with inversion constrained by well-logging and sedimentation microfacies, etc. In the past two years,we gained obvious economic benefit in the adjusting and tapping potential of progressive development. We have drilled several high-efficiency wells with a daily oil production of 30t. We got 50×10⁴t of incremental economic recoverable reserves and 9×10⁴t of annual incremental productive capacity.

Key words: reservoir description, in coordination with multiple subjects, subdivision and correlation, structure interpretation accurately, sedimentation microfacies, remaining oil distribution
