【摘要】：源121-3區(qū)塊在350×100m井網(wǎng)條件下開發(fā)效果差,無法建立有效驅(qū)動(dòng)體系。為改善區(qū)塊開發(fā)效果,探索有效動(dòng)用肇源油田2000萬噸致密儲(chǔ)量的新途徑,開展肇源油田特低滲透性儲(chǔ)層源121-3區(qū)塊加密調(diào)整現(xiàn)場試驗(yàn)。該試驗(yàn)完成了計(jì)劃研究內(nèi)容和實(shí)物工作量,深化了肇源油田地質(zhì)認(rèn)識(shí),研究明確了特低滲透性儲(chǔ)層動(dòng)用界限,形成了完整的特低滲透性儲(chǔ)層加密調(diào)整模式;確定肇源加密技術(shù)排距、經(jīng)濟(jì)排距、可采儲(chǔ)量下限、日產(chǎn)油下限、有效厚度下限等參數(shù);鉆加密井20口,轉(zhuǎn)注油井7口,目前單井日產(chǎn)油0.7t,采油速度保持在1.1%左右,表明滲透率值為1md的肇源油田在175m×50m井網(wǎng)條件下能建立有效驅(qū)動(dòng)體系。
[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.
