Title: Method for selective plugging up highly permeable areas in underground hydrocarbon bearing deposits
Inventor: DZHEJMS I TEKETT MLADSHIJ
IPC: C09K8/88
Filed: 1991-07-02
Granted: 1996-05-20
Abstract: FIELD: selective plugging up highly permeable areas in underground hydrocarbon bearing deposits related to formation of polymer gels. SUBSTANCE: preliminary determination of gel formation on the base of deposit temperature, permeability and porosity, space between well and the area to be plugged up, and volumetric velocity of gel-forming solution supply. Then prepared is gel-forming solution comprising polyacrylamide, cross-link agent based on carboxylate polyvalence metal inhibiting gelatinization, and buffer. Different delay in gelatinization is achieved by way of choosing polyacrylamide concentration, type and concentration of inhibiting agent, type and concentration of buffer on the base of conditions of the given deposit. Delay time may range from several hours to several weeks at deposit temperature around 176 F (80 C), and from several hours to around several days at deposit temperature above around 219 F (104 C). Then prepared solution is injected in the deposit through borehole and held up to gelatinization. The gel plugs up highly permeable areas of underground hydrocarbon bearing deposits in selective way at such temperatures and such distance from the well at which it was impossible earlier. EFFECT: increased oil production. 18 cl, 3 tbl
