【摘要】：本文針對新莊油區(qū)近幾年來注水開發(fā)所面臨的困難,分析了該區(qū)塊的歷年來的深部調(diào)驅(qū)技術(shù)現(xiàn)狀及存在的問題,新莊油區(qū)按儲層類型分類屬于低滲低孔儲層、并且具有束縛水飽和度高,非均質(zhì)性強(qiáng)等特點(diǎn)。伴隨著開采時(shí)間的延長,該區(qū)塊含水率持續(xù)上升,單井產(chǎn)量逐年降低,并且部分油井出現(xiàn)水淹水竄現(xiàn)象,對該區(qū)塊的正常生產(chǎn)產(chǎn)生了嚴(yán)重影響。現(xiàn)有的調(diào)驅(qū)工藝技術(shù)已不能很好的滿足新莊區(qū)塊油藏地質(zhì)的需要,迫切需要對該區(qū)塊的深部調(diào)驅(qū)技術(shù)展開更為深入的研究,從而解決新莊區(qū)塊注水開發(fā)過程中所存在的問題。本文在調(diào)研國內(nèi)外注水井調(diào)驅(qū)技術(shù)的基礎(chǔ)上,開展了適合新莊區(qū)塊的深部調(diào)驅(qū)體系的室內(nèi)配方研究和調(diào)剖施工工藝參數(shù)的優(yōu)化,研制出了適合于新莊區(qū)塊油藏條件的調(diào)驅(qū)體系:交聯(lián)凍膠調(diào)驅(qū)劑和緩膨黏彈顆粒調(diào)驅(qū)劑,交聯(lián)凍膠調(diào)驅(qū)劑配方為0.2%的兩性離子聚合物、0.25%的穩(wěn)定劑及0.25%的交聯(lián)劑,并對其性能進(jìn)行了評價(jià)。通過巖心流動實(shí)驗(yàn)評價(jià)調(diào)驅(qū)劑調(diào)驅(qū)效果,實(shí)驗(yàn)表明:組合使用兩性離子凍膠調(diào)驅(qū)劑和緩膨黏彈顆粒調(diào)驅(qū)劑,能夠提高封堵優(yōu)勢滲流通道的效率,迫使注入的水流方向發(fā)生改變。在室內(nèi)調(diào)驅(qū)劑體系研制的基礎(chǔ)上,將兩性離子交聯(lián)凍膠調(diào)驅(qū)劑和緩膨黏彈顆粒調(diào)驅(qū)劑組合應(yīng)用,開展了適合新莊區(qū)塊的調(diào)驅(qū)工藝設(shè)計(jì)。研制的兩性離子交聯(lián)凍膠調(diào)驅(qū)劑和緩膨黏彈顆粒調(diào)驅(qū)劑通過組合應(yīng)用能夠滿足新莊區(qū)塊油藏深部調(diào)驅(qū)的需要,起到了很好的增油降水效果,5077-1井組、5072井組、5014-1井組平均累計(jì)增油100t左右。
[Abstract]:Aiming at Xinzhuang oilfield in recent years waterflood development difficulties, analyzes the block over the years of deep profile control technology present situation and existing problems, according to the reservoir classification in Xinzhuang oilfield belongs to low permeability and low porosity reservoir, and has the characteristics of high irreducible water saturation, with strong heterogeneity. The production time prolonging, the block water rate continues to rise, the single well production decreased year by year, and some wells flooded water channeling phenomenon, has seriously affected the normal production of the block. The existing flooding technology has not met good new Zhuang block reservoir geology, the urgent need of the deep block the flooding technology to spread more in-depth research, so as to solve the existing Xinzhuang block waterflood development process. Based on the investigation of the domestic and foreign water injection wells adjustable drive technology, carried out for new blocks The optimized formula indoor research and profile control of construction parameters of deep flooding system, suitable for the reservoir conditions of Xinzhuang flooding out: development of crosslinked gel flooding agent and bentonite viscoelastic particles flooding agent, crosslinking gel flooding agent formula for the 0.2% zwitterionic polymer, crosslinking agent, stabilizer 0.25% and 0.25%, and its performance was evaluated. Through the evaluation of core flow experiment of the flooding effect, flooding experiments show that: the use of zwitterionic combination gel flooding agent and bentonite viscoelastic particles flooding agent, can improve the efficiency of sealing edge flow channel, the flow direction of the injection force change. Adjustable flooding agent system developed in the laboratory, the amphoteric crosslinked gel flooding agent and bentonite viscoelastic particles flooding agent combination, carried out for Xinzhuang block flooding process design. The development of amphoteric crosslinked gel flooding The combination agent and slow swelling viscoelastic particle flooding agent can meet the needs of deep reservoir adjustment and flooding in Xinzhuang block by combination application. It has played a good role in increasing oil and precipitation. The 5077-1 well group, 5072 well group and 5014-1 well group have increased oil accumulation by 100t on average.
