海拉尔盆地复杂断块油藏开发钻井地质跟踪方法探讨

Geological Tracking Approach of Development Drilling in Complex Fault Block of Hailar Basin

对海拉尔盆地复杂断块油藏开发钻井地质跟踪方法进行了探讨:依据开发井、探评井试油资料,结合投产井生产动态,对部分井区构造低部位井油层重新解释(区块内每个小段块有效厚度解释标准各有差异),完善了有效厚度解释标准,满足了开发钻井需求;在开发钻井过程中,边钻井边认识边完善,随钻跟踪调整,优化井位运行,减少无效进尺,节约开发钻井成本;拓宽开发领域,及时发现新含油层系。实际跟踪效果表明,该方法既综合提高了钻井成功率,保证开发钻井效果,又节约开发钻井投资成本,提高了油田开发经济效益,对保证开发井钻井效果和产能建设任务的按期完成具有极其重要的意义。

This paper discusses the drilling tracking method of complex fault block reservoir in Hailar Basin.On the basis of well testing data of development wells,exploration and evaluation wells,the reservoirs of the lower part wells of the structure are interpreted combined with the dynamic production in productionwells at the same time.The effective thickness interpretation standards of each small block is different between each other.After the interpretation,the standards are perfected and can meet the needs of development drilling;in the development drilling,it is understood,perfected while drilling.Besides,well locateon is optimized,invalid footage is reduced and the cost of drilling is saved.The actual results show that the method is used for improving the success rate of drilling,ensuring the development of drilling effect.Further more,it saves drilling cost,improves the economic benefit of oilfield development.Thus it has extremely vital significance to ensure the development of drilling and production capacity construction for completion on schedule.
