聚丙烯酰胺在二次采油可以用嗎?

       聚丙烯酰胺作為油田助劑,有乳液型和固體兩種形態(tài),它是一種多功能添加劑.在油田鉆井工藝中用于泥漿的增調(diào)劑、穩(wěn)定劑和沉降絮凝制以改進泥漿的流變性;能改進懸浮顆粒的大小,提高懸浮力,加速原油的過濾、分離。作為土壤結(jié)構(gòu)成型劑,使井壁表面抗沖擊性能提高,鉆井通過啟層時使不易分散的液漿獲得優(yōu)質(zhì)的分離效果。使部分水解均聚丙烯酰胺與甲醛、乙二醛等發(fā)生羥甲基化反應(yīng)而生成側(cè)鏈含甲基的產(chǎn)物,在原油生產(chǎn)中可獲得滿意的效果。

       在二次采油時將聚丙烯酰胺PAM注人鹽水中,能夠有效提高鹽水的噴射能力,從多孔的巖石表面有效地將原油萃取下來。在水~油乳液中加人聚丙烯酰胺PAM,可明顯地降低乳液的粘度。加人貯油池內(nèi),可降低油池表面的含水量,降低采用成本。油田助劑的種類很多,聚丙烯酰胺PAM與聚丙烯酸鉀K-PAM都可以稱作油田助劑,但是兩者是兩種不同的油田助劑,K-PAM聚丙烯酰胺鉀鹽中含有鉀離子能夠很好的抑制巖層防坍塌是油田鉆井作業(yè)必備的油田助劑。在石油開采中,可增加注人水的粘度,避免擊穿油層,提高采油率。在di三次采油中用作增稠劑,增加驅(qū)油能力,提高油床開采效果。在油田領(lǐng)域內(nèi),更新的陰、陽離子的聚丙烯酰胺PAM可用于保護注人的地下水從啟孔滲透并凝集回收原油,提高油井生產(chǎn)的經(jīng)濟性,控制水分向油層摻入。

       此外,乳液型聚丙烯酰胺還用于壓裂液添加劑、潤滑劑、降阻劑等。在油田化學中,聚丙烯酰胺PAM是多用途的添加劑,如鉆井液、洗井液、注水采油及提高采收率等都起著重要的作用。利用聚丙烯酰胺PAM線型大分子結(jié)構(gòu),在湍流狀態(tài)下很容易按流動方向取向成長線條狀,抑制湍流發(fā)展。聚丙烯酰胺可作為降摩劑的理想材料,在原油的長距離管道輸送中,加人0.lmg/L(原油量) 聚丙烯酰胺PAM,就能大大地降低原油輸送阻力,從而降低能耗。



英文:Can polyacrylamide be used in secondary oil recovery?
    Polyacrylamide as oil field additives, emulsion and solid form, it is a kind of multifunctional additives. In the oil field drilling process used for mud adjustability stabilizer and sedimentation flocculation to improve the rheological properties of mud; It can improve the size of suspended particles, improve the suspension force, and accelerate the filtration and separation of crude oil. As a soil structure forming agent, it improves the impact resistance of the well wall surface, and makes the liquid slurry which is not easy to disperse get high quality separation effect when drilling through the layer. Partial hydrolyzed homopolyacrylamide reacts with formaldehyde, glyoxal and so on to produce side chain products containing methyl groups. Satisfactory results can be obtained in crude oil production.

      Injecting polyacrylamide PAM into brine during secondary oil recovery can effectively improve the injection capacity of brine and effectively extract crude oil from the porous rock surface. Adding polyacrylamide PAM into water-oil emulsion can obviously reduce the viscosity of the emulsion. Adding the oil storage tank can reduce the water content on the surface of the oil tank and reduce the cost. There are many kinds of oil field additives, polyacrylamide PAM and polyacrylic acid potassium K-PAM can be called oil field additives, but the two are two different oil field additives, k-PAM polyacrylamide potassium salt contains potassium ions can be very good to inhibit rock formation collapse is necessary oil field additives drilling operations. In oil exploitation, it can increase the viscosity of injection water, avoid the breakdown of oil layer, and improve oil recovery rate. It is used as thickener in di tertiary oil recovery to increase oil displacement capacity and improve oil bed recovery effect. In the field of oil fields, the updated negative and cationic polyacrylamide PAM can be used to protect the groundwater injection from the hole opening infiltration and agglutination recovery of crude oil, improve the economic production of oil Wells, control water to the oil layer incorporation.



In addition, emulsion polyacrylamide is also used as fracturing fluid additives, lubricants, resistance reducer and so on. In oilfield chemistry, polyacrylamide PAM is a versatile additive that plays an important role in drilling fluid, well flushing fluid, water injection and enhanced oil recovery. Using polyacrylamide PAM linear macromolecule structure, it is easy to grow lines according to the flow direction in turbulent state and restrain the development of turbulence. Polyacrylamide can be used as an ideal material for friction reduction agent. In the long-distance pipeline transportation of crude oil, 0. LMG /L(crude oil) polyacrylamide PAM can greatly reduce the resistance of crude oil transportation, so as to reduce energy consumption.
