Abstract

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
