Application of heat-resistant and salt-tolerant particle profile control and displacement agent in Wennan Oilfield
Online published: 2007-12-15
Wennan Oilfield is a typical reservoir characterized by high temperature and high salinity. It is now in high water cut period, with water flooding already in the main formation. Particle profile control and displacement agents are developed to improve the oilfield development effect. The tests on heat stability, saltresistant capability and rate of expansion show that the profile control and displacement agents with a good performance of salt-tolerant and heat-resistant are suitable to the formation characteristics of Wennan Oilfield. Aimed at the main object of profile control and displacement which is to find and recover the residual oil, the principles for selecting profile control and displacement blocks are determined. Water drive front and real time monitoring technologies are adopted in the practical operation, and the relevant satisfactory results are obtained.
