Gu Dong Oil Field Water Treatment Agent Evaluation And Application

Properties of crude oil and formation properties of Gudong oilfield are complex.In order to stabilize the output of crude oil,oil field development and the application of many new technologies and methods to improve the recovery rate of oil production.The implementation of the new oil recovery technology is a good foundation of oil field production,yield,but various measures above by chemical method,when various chemical agent injection strata,which makes the composition and properties of water becomes more and more complex,the non hydrocarbon compounds in crude oil and metal,heteroatom content increased,an increase of crude oil dehydration the difficulty,the final effect of water quality and water injection effect.At the same time,due to the interaction of water injection of various drugs,so that the polymer degradation,affecting the viscosity of polymer solution,resulting in the polymer flooding greatly decreased.The influence of water,part of water injection well clogging,to make increased injection pressure,water absorption index decreased,water injection effect weakening.At present from the water quality monitoring results,six water injection station in Gudong oilfield water quality indicators have not reached the corresponding block standards,Especially the bacterial content of waste oil content,seriously exceed the standard..Therefore,the improvement of water quality has become an urgent problem to solve.This paper based on the characteristic of production in Gudong oilfield water injection system,analysis of various quality indexes in the causes of the present production conditions failed to meet,on the basis of water quality index developed from starting,combined with the current field of water treatment chemicals application and domestic water treatment chemicals application,to improve the water quality evaluation and optimization of chemical reagents water injection system,and ultimately develop a joint station to different water treatment chemicals application schemes of different water quality indexes to the.
