摘要:

油田化学剂的使用是实现油田储层改造、原油增产、残余油开采以及原油输送的重要手段,在二次采油、三次采油、压裂酸化等油井增产措施与原油集输过程中均使用了大量的油田化学剂。这些油田化学剂部分直接进入原油中;部分与原油储层发生相互作用,以作用后产物的形式进入原油中,从而对原油后续加工过程产生较大影响。在调研了我国克拉玛依、塔里木、吐哈、长庆、青海等西部五大油田原油采输过程中使用的油田化学剂种类和组成后,开展了采油化学剂与原油储层之间的相互作用研究,给出了残余油田化学剂与采油化学剂-原油储层之间的作用产物在原油中的存在形式

Abstract:

The application of oilfield chemicals is important to improve reservoir,enhance recovery,produce remaining oil and transport crude.In secondary recovery,tertiary recovery,fracturing and acidizing,as well as oil gathering and transportation,a lot of oilfield chemicals are used.The chemicals partially get into crude directly,and the rest interacts with reservoir,the reacted products enter crude,so there is considerable influence on following up crude oil processing.After reviewing and researching the types and components of the oilfield chemicals used in production and transportation in such western part oilfields as Karamay,Tarim,Tuha,Changqing and Qinghai,the interaction between recovery chemicals and reservoirs is studied,the existence form of the interaction products in crude oil among residual oilfield chemicals and oil production chemicals- reservoirs is identified.

Key words: oilfield chemicals, reservoir improvement, petrochemistry, acidizing, fracturing, oil production enhancement
