深部液流转向剂ZYTQ01在濮城油田的调驱先导试验

为了满足液流深部转向而自行研制了深部液流转向剂ZYTQ01，并在濮城油田南区沙二上2 3油藏开展了调驱先导试验。介绍了ZYTQ0l的深调机理和驱油机理．对其性能(包括注入水对ZYTQ01膨胀度的影响、流动压力与流量的关系、纵向调剖效果、改善平面波及效果、微观驱油效果)进行了试验评价。现场试验结果表明，采用ZYTQ01调驱工艺进行治理后，凝胶颗粒在地层深部调剖成功，使受益油井增油降永效果显著。

Deep Adjusting and Displacement Pilot Test of In-depth Fluid Flowing Diverting Agent ZYTQ01 in Pucheng Oilfield

A in-depth fluid flowing diverting agent ZYTQ01 is developed by ourselves to meet the needs of fluid flowing diverting in deep zone, by which in-depth adjustment and oil displacement pilot test is performed in Reservoir 2 + 3 in the upper member of Es3 of south region in Pucheng Oilfield, the in-depth adjustment and displacement mechanisms are introduced. Experimental evaluation is made on its performance (including the effect of injected water on the degree of expan- sion, the correlation between pressure and flowrate. vertical profile controlling result, improving the areal sweep efficiency and micro-displacement efficiency). The result of field testing shows that after the treatment is made with ZYTQ01 displacement process , in the in-depth reservoir profile control, the gelling particles are successfully used, with evident oil production increase and water reduction.
