钻井、完井、采油是石油勘探开发过程中的重要组成部分.提出了以采油优先的一体化设计模式的理念,在钻井工艺设计之初就考虑井身剖面对后期完井、采油的影响,建立钻井服务于采油的设计理念,改变完井工艺与举升工艺的被动设计状态,实现对油井全生命周期的过程化管理.在分析钻井井身剖面对后期采油影响因素的基础上,利用层次分析法和模糊评判理论,建立抽油机井井身剖面评价指标体系,优选出最佳的井眼设计轨迹.通过现场应用表明,以采油优先的一体化设计模式,极大地改善了后期采油管理的不利局面,为油田长期有效开发提供了借鉴.
鑽井、完井、採油是石油勘探開髮過程中的重要組成部分.提齣瞭以採油優先的一體化設計模式的理唸,在鑽井工藝設計之初就攷慮井身剖麵對後期完井、採油的影響,建立鑽井服務于採油的設計理唸,改變完井工藝與舉升工藝的被動設計狀態,實現對油井全生命週期的過程化管理.在分析鑽井井身剖麵對後期採油影響因素的基礎上,利用層次分析法和模糊評判理論,建立抽油機井井身剖麵評價指標體繫,優選齣最佳的井眼設計軌跡.通過現場應用錶明,以採油優先的一體化設計模式,極大地改善瞭後期採油管理的不利跼麵,為油田長期有效開髮提供瞭藉鑒.

Well drilling, completion, and oil production are regarded as important constituent steps in the procedure of petroleum exploration?and?development.?A?concept?of?integral?design?pattern?with?oil?production?as?priority?is?proposed?and?developed.?The?influ-ences?of?well?profile?on?well?completion?and?oil?production?at?later?stages?are?taken?into?consideration?at?the?beginning?of?drilling?design,?setting up the concept that drilling serves oil production, which changes the passive status of completion and lifting designs, and imple-ments?the?process?management?for?wells?during?the?whole?life?cycles.?Based?on?the?observation?of?the?influencing?factors?of?well?profile?affecting oil production at later stages, the analytical hierarchy process and the fuzzy evaluation theory are applied to establish wellbore profile?evaluation?indicators?for?pumping?wells,?and?to?optimizing?borehole?trajectory.?By?the?field?applications?in?North?China?Oilfield,?it is shown that novel pattern is able to improve the disadvantages in oil production management at later stages, and to provide references for?sustainable?development?of?oilfields.
