S15井是中石化国勘在伊朗雅达项目部署的第一口严格意义上的水平井,水平段长900米,倾角89.94度。伊朗雅达区块主要是以灰岩地层为主中间夹杂着不均质的泥质含量,多有泥岩夹层出现,针对之前(由伊朗国家石油公司勘探开发)该区块大量油井地址资料缺失的情况,在S15井的钻进过程中,克服了诸多难题和未知因素,成功的完成了该井的工作任务。S15井的顺利施工补充的该区块的地址资料,为该区块的其他水平井部署、设计和施工起到了重要的指导意义。 Well S15 is the first horizontal well to be deployed by Sinopec National Exploration at the Astec project in Iran, with a horizontal section of 900 meters and a dip angle of 89.94 degrees. In the Yada block in Iran, the main limestone stratum is mainly composed of an inhomogeneous muddy content with many mudstone intercalations. In view of the lack of data on a large number of oil wells in this block (previously explored and developed by Iran’s National Petroleum Company) In the process of well drilling in S15, many difficulties and unknown factors were overcome, and the well’s work was successfully completed. The address information of the block supplemented by the smooth construction of well S15 has played an important guiding role in the deployment, design and construction of other horizontal wells in the block.
