STUDY ON ORGANOSILICON HIGH TEMPERATURE SAND CONSOLIDATING TECHNIQUE AND APPLICATION OF VISCOUS CRUDE EXPLOITATION

klamayi 6-9 viscous crude block are sandstone reservoir, formation structure is unconsolidated, the thermal recovery by injecting high temperature and high pressure steam will damage oil reservoir more heavier, make sand producing of producing well more seriously, which influence normal producing of this viscous crude reservoir block.Since 1991 wire wrapped sand control of mechanical sand control and hydroxy-aluminium sand control of chemical sand consolidating measures have been taken, but because sand control scope is limit, effect is bad, consolidating cycle is short, cost is high and so on, these measures can’t be used widely.Without above disadvantages organosilicon modified sand consolidating technique has good high temperature sand consolidating property, tests indoors show under 300℃, compression strength of optimized organosilicon high temperature sand consolidating agent is above 4MPa, at the same time this agent take less damage to the formation, water phase permeability is above 0.60.the high temperature sand consolidating agent has been tested in 10 wells in field of 6-9 block viscous crude reservoir, efficiency is 98%, crude oil production is increased by 1180.7tons.After treatment, sand content of crude oil is very little.This technique has get satisfied effect, be worthwhile being popularized.
