摘要： A system includes a downhole tool having a housing and a passage extending through the housing, where the passage includes an inlet configured to receive a flow of a wellbore fluid and an outlet configured to discharge the flow of the wellbore fluid. The downhole tool includes a heating element configured to heat the flow of the wellbore fluid and to enable the flow of the wellbore fluid to transition to a single-phase fluid flow within the passage. The downhole tool includes a phase composition sensor positioned adjacent the passage and configured to provide feedback indicative of formation of the single-phase fluid flow. The system includes a controller configured to monitor a power consumption of the heating element and to determine an enthalpy of the wellbore fluid based in part on the power consumption and the feedback from the phase composition sensor.

摘要： The disclosure relates to a method for producing heavy oil by generating solvents in situ in the reservoir, an electric heating device is used to heat up the crude oil in the reservoir near the wellbore to the target temperature. Chemical reaction additives are injected into the heating section to meet the preset reaction conditions for the high temperature thermal cracking and aquathermolysis of crude oil, so as to generate light hydrocarbon components and gases. Under the effect of heat and gravity, the light hydrocarbon components and gases rise to the steam chamber. The light hydrocarbons and some gases that move to the vapor-liquid interface of the steam chamber are dissolved in the crude oil to reduce the viscosity of crude oil and increase the production rate of crude oil.

摘要： Disclosed is a spirally heating submarine pipeline including: a conduit which transports a high temperature high pressure fluid from a submarine oil well; and a heating unit disposed in a spiral structure inside based on an outer circumferential surface of the conduit. The heating unit includes an electric heating wire that is installed along the spiral structure to generate heat; a heat insulator that is installed in the form of fully surrounding the electric heating wire and preserves the generated heat; and a heat insulating cap for isolating the heat insulator from the conduit or the heat insulating layer and is provided so as to increase the temperature of the flow in the pipe to prevent the production of a pipe flow interfering material when the fluid is transported in the conduit.

摘要： System and methods for heating boreholes include laser generators to trigger a chemical reaction to break down heavy hydrocarbons in boreholes. The systems and methods use arrays of laser generators at the borehole surface or within the borehole to heat the heavy hydrocarbons. The systems and methods may include hydrocarbon sensors within the borehole to detect gas seepage resulting from heating of the heavy hydrocarbons.

摘要： Systems and methods for forming a permanent plug in a subterranean formation include providing a solution of colloidal silica and pumping the colloidal silica into a bore of a subterranean well so that the colloidal silica penetrates pores of the subterranean formation. The colloidal silica within the pores of the subterranean formation is dehydrated to form a glass-like material within the pores of the subterranean formation.

摘要： A system comprises a casing and a liner. The liner is concentric with the casing and the casing is disposed in a borehole. A layer of material disposed between the liner and the casing. The layer of material forms a first bond with the liner and a second bond with a metal alloy disposed on an inner surface of the casing thereby enabling hanging the liner from the casing. The layer of material is an expandable metal disposed upon a tapered surface of the liner. The layer of material contacts the metal alloy along a circumferential surface of the layer of material. The layer of material comprises a product of an exothermic reaction package; where a product is produced by an exothermic reaction of a metal with a metal alloy.

摘要： A method and system of monitoring fluid flow in a wellbore. One or more space-distributed temperature input pulses are induced into at least a portion of a fluid in a housing in the wellbore. The housing has at least one cavity and one or more flow ports. A temperature response pulse, caused by the temperature input pulses, are sensed at one or more locations downstream of the cavity and a flow rate of the fluid through the cavity is determined. The flow rate may be determined based on one or more characteristics of the temperature response pulse, and a Retention Time Distribution (RTD) of the cavity.
