高3-6-18块构造上位于高升油田高二、三区的东北部,属深层巨厚稠油油藏,为提高区块的整体开发效果,2008年5月开展了火驱先导试验,为进一步完善火驱井网,需要实施新井和侧钻井,在考虑到地层压力低和火烧高温等因素,研究优化了适合高3618块火烧区块的钻完井配套技术,重点优化了钻井液体系、钻完井工艺,确保了火驱试验的顺利进行,为提高区块开发效果奠定了基础。
The high 3-6-18 blocks are structurally located in the northeast of Gao 2 and 3 districts of Gaosheng Oilfield and belong to deep and thick heavy oil reservoirs. In order to improve the overall development effect of the blocks, pilot tests of fire flooding were carried out in May 2008 as In order to further improve the fire-driven well pattern, it is necessary to implement new wells and side-drilled wells. In consideration of factors such as low formation pressure and high temperature of fire, research and optimization of drilling and completion matching techniques for high-grade 3618 blocks were optimized and the drilling fluid system was optimized. Drilling and completion technology to ensure the smooth progress of the fire drive test, in order to improve the effect of block development laid the foundation.
