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

摘要： 冀东油区在老区调整挖潜工作中,进行适合油田实际的油藏精细描述工作。其基本要点是以地质为主导的多学科协同描述,修正(或重建)砂体格架模型,精细解释油层顶面微构造,测井约束反演与沉积微相结合描述砂体平面分布等。近两年在此基础上的滚动开发调整挖潜已打出一批日产油30t以上的高产高效井,新增经济可采储量50×10⁴t,新增原油年生产能力9×10⁴t,取得了明显的经济效益。
