Example Embodiment

[0025] Example 1

[0026] The method of co-production of geothermal and oil and gas in oil or natural gas exploitation includes the following process flow: after the production well is drilled, casing 1 is inserted and cemented, heat conduction cementing is performed in the high temperature section of the formation, and insulation cementing is performed in the low temperature section of the formation ; Perforating and fracturing from the casing inside the oil layer or gas layer is used as the production channel 2. At different heights above the oil layer or gas layer in the high temperature section of the formation, perforating and fracturing from the casing to the rock layer, and into the fracture Fill the thermal conductive filler to form a conductive zone 3 extending from the casing 1 to the rock formation; insert a short pipe 4 at each segmented perforation and expand the tube to seal the through hole 5 on the casing to ensure that the casing 1 does not release pressure and ca...

Abstract

The invention relates to the technical field of development of geothermal energy, in particular to a method for co-mining of terrestrial heat and oil gas in oil or gas mining. The method comprises thefollowing process flows: drilling a producing well, then running a casing and performing cementing, performing heat conduction cementing in a stratum high-temperature segment, and performing heat insulation cementing in a stratum low-temperature segment; performing perforation and fracture from the casing in an oil layer or a gas layer and taking as production channels, performing segmented perforation and fracture from the casing to a rock stratum within different heights, positioned in the stratum high-temperature segment, above the oil layer or the gas layer, and filling cracks with heat conductive fillers so as to form heat conduction bands extending from the casing to the rock stratum; running short pipes into positions of segmented perforation, and enabling expanding pipes to seal through holes ejected from the casing; putting a conveying pipe into the casing, and enabling the bottom end of the conveying pipe to stretch into the oil layer or the gas layer; installing packers below segmented perforation segments above the oil layer or the gas layer; and finally installing a condensing segment of a gravity heat pipe heat exchanger butted with the casing on the ground, and enabling the conveying pipe to go through the gravity heat pipe heat exchanger.

Description

technical field [0001] The invention relates to the technical field of energy development, in particular to a method for co-extraction of geothermal heat and oil and gas in oil or natural gas exploitation. Background technique [0002] The energy industry is the basic industry of the national economy and the material basis for realizing modernization. All countries in the world regard the establishment of a reliable, safe and stable energy supply guarantee system as one of the strategic issues of the national economy. [0003] Geothermal resources are a kind of clean and renewable energy without pollution. At present, only drilling, casing, cementing, heat extraction, and heat exchange are required for the utilization of geothermal energy in the middle and deep layers of the earth's surface, in order to form geothermal wells that can extract heat and utilize them. [0004] Oil and natural gas are important strategic materials related to the national economy, people's livelih...
