    摘要:

    为了经济有效地开发鄂尔多斯盆地东部浅层、低渗透、低丰度油藏,陕西延长石油(集团)有限责任公司在该地区部署了第一口浅层大位移水平井——X平1井。该井施工克服了浅地层造斜稳斜控制困难、长水平段携岩困难、起下钻摩阻大、钻头加压困难等一系列技术难题,完钻井深1366 m,垂深499.16 m,水平位移1003.58 m,位垂比2.01∶1,该井的顺利完钻预示着鄂尔多斯盆地东部浅层、低渗透、低丰度油藏高效开发成为可能。

    Abstract:

    Well XPing1 is the first shallow extended reach horizontal well drilled by Yanchang Petroleum to develop the shallow, low permeability and low abundance oil reservoirs of Eastern Ordos Basin. Technical challenges of angle building and holding control, cuttings transportation in long horizontal hole section, large frictional resistance during trip and pressurized bit were overcome in the construction of this shallow horizontal well, which was finished at measured depth of 1366m with 1003.58m horizontal extension and 499.16m vertical depth. The ratio of horizontal extension to vertical depth is 2.01∶1. The finishing drilling of this well indicates that the high effective development of shallow, low permeability and low abundance oil reservoirs of Eastern Ordos Basin has become possible.
