【摘要】：源121-3区块在350×100m井网条件下开发效果差,无法建立有效驱动体系。为改善区块开发效果,探索有效动用肇源油田2000万吨致密储量的新途径,开展肇源油田特低渗透性储层源121-3区块加密调整现场试验。该试验完成了计划研究内容和实物工作量,深化了肇源油田地质认识,研究明确了特低渗透性储层动用界限,形成了完整的特低渗透性储层加密调整模式;确定肇源加密技术排距、经济排距、可采储量下限、日产油下限、有效厚度下限等参数;钻加密井20口,转注油井7口,目前单井日产油0.7t,采油速度保持在1.1%左右,表明渗透率值为1md的肇源油田在175m×50m井网条件下能建立有效驱动体系。
[Abstract]:The source block 121-3 poor development effect in the 350 * 100m well network condition, to establish effective drive system. In order to improve the effect of block development, to explore a new way for the effective use of Zhaoyuan oilfield 20 million tons of dense reserves, carried out in Zhaoyuan oilfield of low permeability reservoir in block 121-3 source adjustment field testing. The tests completed the research plan the content and physical workload, deepen the understanding of geological research in Zhaoyuan oilfield, the reservoir boundary layer with low permeability, the formation of the encryption adjustment mode of super low permeability reservoirs complete; Zhaoyuan encryption technology economic row spacing, row spacing, lower limit of recoverable reserves, oil production of lower limit of the effective thickness and other parameters; infill drilling 20, Zhuanzhu 7 wells, the oil production of single well 0.7T, oil production rate remained at around 1.1%, that the effective driving system is established for 1md permeability values in Zhaoyuan oilfield 175m * 50m well network condition.
