聚表剂具有高增粘性、自交联能力,在地层中吸附滞留量大,同时遇油乳化后粘度大幅升高,易造成堵塞;堵塞物主要为聚表剂裹挟了粘土、原油和细菌代谢产物形成成的凝胶体系;复合酸和氧化剂对聚表剂堵塞井具有一定的解堵效果,但受地质条件影响较大。
聚錶劑具有高增粘性、自交聯能力,在地層中吸附滯留量大,同時遇油乳化後粘度大幅升高,易造成堵塞;堵塞物主要為聚錶劑裹挾瞭粘土、原油和細菌代謝產物形成成的凝膠體繫;複閤痠和氧化劑對聚錶劑堵塞井具有一定的解堵效果,但受地質條件影響較大。
취표제구유고증점성、자교련능력,재지층중흡부체류량대,동시우유유화후점도대폭승고,역조성도새;도새물주요위취표제과협료점토、원유화세균대사산물형성성적응효체계;복합산화양화제대취표제도새정구유일정적해도효과,단수지질조건영향교대。
Polymer surfactant with Gao Zeng viscous, self-crosslinking ability, in the formation of adsorption, while encountering oil emulsified viscosity significantly increased, easy to cause blockage; blockage for polymer surfactant together with clay, oil and bacterial metabolites formed into gel system; composite acid and an oxidizing agent to the polymer surfactant jam the well has a blocking effect, but by the geological condition the impact is bigger.
