储层评价有助于水平井工艺及开发效果的提高

在分析锦27块油藏地质特征的基础上，采用物质平衡方法研究平面剩余油分布规律，利用吸水剖面研究纵向剩余油分布，从而评价出水平井储层的产能。准确的地质设计为锦27-平1井井眼轨迹提供依据。并且采用适合该区块的钻井工艺技术。充分利用有线随钻和MWD测斜仪加双伽马的先进系统，提高轨迹控制的精度，增大油层的钻遇率，提高水平并的开发效果。实践证明，开发锦27块这样的断块油气田，采用水平井开发是经济而有效的。

The Reservoir Evaluation Increase the Technology and Development Effect of the Horizontal Well

Depend on the base of analyses to geological characterization of oil reservoir in Jin 27 block the distribution rule of remaining oil on plane is researched using the method of matter balance and the distribution rule of remaining oil on portrait is studied using the sop up section,so the reservoir productivity of horizontal wells is appraised.By the exact geological design the well track of well Jin 27 P1 could be obtained.During the operation,the drilling technique suit the block was adopted,the MWD and gamma system were utilized sufficiently.So the well track measuring was convenient and in time,the precision of track control was increased,the reservoir drilled chance was enhanced and the develop effect was improved.
