Patent

CA 2247334

This invention relates to a process for increasing the effectiveness of production chemicals by reducing the number of squeezing and shut-in operations needed to increase the production rate from an oil well. The process comprises injecting into an oil-bearing rock formation matrix a water- miscible formulation comprising: (a) a water-miscible surfactant which is an alkyltriglycol ether and (b) at least one water-miscible oil field or gas field production chemical, said (a) and (b) being introduced either as a pre- formed, single, homogeneous composition, or simultaneously in parallel or sequentially in either order into the rock formation characterised in that after introduction of (a) and (b) into the oil-bearing rock formation, the well is shut-in for a period and, subsequently, the oil-bearing rock formation matrix is over-flushed with an oil.

Cette invention porte sur un procédé permettant d'accroître le rendement d'agents chimiques de production en réduisant le nombre d'opérations de compression et de phases d'attente nécessaires pour augmenter le taux de production d'un puits de pétrole. Le procédé consiste à injecter dans une matrice de formation rocheuse pétrolifère une formulation comprenant: a) un agent tensioactif miscible à l'eau, un éther alkyltriglycol et b) au moins un agent chimique de production de champ pétrolifère ou gazéifère miscible à l'eau, ces substances (a) et (b) étant introduites, soit sous la forme d'une composition préformée, unique et homogène, soit simultanément, en parallèle ou l'une à la suite de l'autre et ce, dans n'importe quel ordre. Le procédé a ceci de particulier qu'après l'introduction des substances (a) et (b) dans la formation rocheuse pétrolifère, on met le puits en phase d'attente et l'on injecte dans la matrice de formation rocheuse pétrolifère un fluide sans sable, de l'huile en l'occurrence.
