中原高温高盐油藏疏水缔合聚合物凝胶调剖剂研究

针对中原油田高温(>80℃)、高盐度(>50 g/L)、高硬度(>1 g/L)砂岩油藏,研制了地下成胶的高热稳定性聚合物凝胶调剖剂。所用聚合物为疏水缔合聚合物AP-P4,M=9.0×106,HD=27%,疏水基摩尔分数0.2%;交联剂为可生成酚醛树脂的3种化合物;调剖剂胶液用矿化度160 g/L的马寨油田污水配制;实验温度95℃。根据形成的凝胶黏度(95℃,1.1 s-1)确定交联剂各组分用量为:MZ-YL 0.429%,MZ-BE 0.060%,MZ-XS 0.012%;酸度调整剂用量0.12%;成胶时间10~15小时。2.5、3.0、3.5 g/L AP-P4的凝胶在95℃老化100天后黏度保持在~40 Pa.s及以上。初配制胶液在3000 r/min下剪切15分钟后黏度降低87.5%~89.0%,但成胶后和老化过程中凝胶黏度只比未剪切样降低17.1%~6.6%。3.5 g/L AP-P4的调剖剂对~1μm2的6支储层岩心的堵塞率在88.1%~95.8%范围,平均93.3%,造成的残余阻力系数在15.2~28.6范围,平均19.8,使渗透率级差2.3~8.0的4组双人造岩心的注水流量比发生不同程度的反转。认为该凝胶调剖剂高温下稳定性好的原因,是强化学交联密度低,因而凝胶脱水收缩作用弱。图2表5参5。

Assessing the Core Resources in the Environmental Management System From the Resource Perspective and the Contingency Perspective

The purpose of this paper is twofold. The first objective is to examine the core resources that make environmental management system (EMS) a potential basis of sustainable competitive advantage from the resource-based view of the firm. The second objective is to investigate the set of core resources from the contingency perspective. Particularly, experience in implementing other manufacturing systems and the stage of EMS implementation were tested as the contingency factors. The proposed model and its related hypotheses were tested using structural equation modeling on a large-scale database consisting of 1453 respondents. The results showed that it is the tacit resources within an EMS, in the form of top management team's strategic perception, cross-functional cooperation, and environmentally responsible suppliers, which help explain firmspsila operational performance. The findings provided the general principles in investment decisions of EMS. However, the results also demonstrated that the pattern of the core resources varies across firms with different experience in other manufacturing systems and at different stages of EMS implementation. As a result, there is no standard bundle of critical resources for each firm. Rather, firms need to tailor their resource investment decisions in light of these factors beyond the general principles.
