TH18763A - Method for stimulation of liquid flow in the well. - Google Patents

Abstract

The method of stimulating the flow of water into the pond from the rocky basins around the ponds is sealed in such a way that increasing the pressure of the pond can be achieved. The carbon dioxide liquid is applied inside the sump at the pressure of the bottom hole. So that liquid carbon dioxide solidifies within the pond and forms solid carbon dioxide, and the solidification of carbon dioxide will Continue to do in the pond Until the desired level of filling of the pond A sealed sump containing Solid carbon dioxide is left with sufficient time. In order to sublimate the solids of carbon dioxide in the sealed sump. And the remaining pressure will be released in the seal sump and the sealing cap will Being brought out of the pond

Claims (9)

1. a method of stimulating the flow of water into a pond from a rocky basin surrounding a well-formed pond Embrace the steps of Sealing the sump in a manner that increases the sump pressure can be achieved by providing liquid carbon dioxide into the sump at the pressure of the bottom hole. So that the liquid car Bondioxide solidifies in the pond and forms solid carbon dioxide. And there is a constant supply of - liquid carbon dioxide into the pond. Until the filling of the pond at the desired level And will leave a sealed sump containing solid carbon dioxide Until it's time to sublimate Solid carbon dioxide present in the sealed sump And will release the remaining pressure in the sealed sump. And will release the sealing cap from the pond 2. Method according to claim 1, where the sealing of the well consists of laying the sealing path. Seal on well or in well formwork and provide a anti-scale pathway 3. Method according to claim 1, which will consist of further emptying of gas car sealed sump. Bondoxide before liquid carbon dioxide infusion 4. Method according to claim 1, where the procedure of the method has been repeated several times in order to obtain Water flow as needed 5. Method according to claim 1, where the pressure at the bottom hole is adjusted so that it is within Between approx. 0 and 7 lbs / in 2 6. Method according to claim 1 to be continued in connection with control or killing of Bacteria in the pond 7. Method according to claim 1 that will continue with the removal of slag in the pond 8. Method according to claim 6, where the sublimation of solid carbon dioxide inside the pond Sealing will cause pressure inside the sealing sump. And will release carbonic acid into the rocks of the well 9. Method according to claim 1, where the pressure at the bottom hole is sufficient to ensure rigidity. The body of water within the formation and surrounding rock layers
