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。
To adjust and tap the potential of maturing tracts of Jidong oil field, we carried on the accurate reservoir description to meetthe needs of the oil field. The basic points are: multi-disciplinary description while geology plays a leading role, correcting (orreconstructing) 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 micro facies, etc.In the past two years, we gained obvious economic benefit in the adjusting and tapping potential of progressive development. Wehave drilled several high-efficiency wells with a daily oil production of 3Ot. We got 50 × 104t of incremental economic recoverablereserves and 9 × 104t of annual incremental productive capacity.
