Abstract: A permeable cement stone fracturing exploitation method for non-conventional oil and gas layer comprising the following processes: transporting and storing a supercritical carbon dioxide to a well site; selecting, transporting, and storing an oil well cement and admixtures to the well site; mixing the oil well cement and the admixtures into a first mixture, forming a cement slurry; pumping the supercritical carbon dioxide and the cement slurry respectively into a high pressure mixer; automatically mixing the supercritical carbon dioxide and the cement slurry into a second mixture by the high pressure mixer; continuously on-line monitoring and temporarily storing the second mixture; and injecting the second mixture into the non-conventional oil and gas layer for fracturing to form a reticulate artificial fracture; the second mixture is automatically heated, pressure reduced, gasified, solidified, carbonic acid dissolved and eroded, leached to form the a permeable cement stone.

Abstract: Disclosed is a permeable cement stone fracturing exploitation method for non-conventional oil and gas layer such as tight oil and gas, shale gas, coal-bed gas, combustible ice and so on. The method comprises the following complementary processes and embodiments: transporting, storing and pumping process for supercritical carbon dioxide; transporting, storing, preparing and pumping process for fracturing cement slurry; process for mixing the supercritical carbon dioxide and the cement slurry; process of fracturing the supercritical carbon dioxide and the cement slurry on ground; process of forming a permeable cement stone under the ground; and so on.
