Abstract
The invention relates to a thick oil thermal production well saturated steam flow metering method for thick oil thermal production steam drive steam-injection well high-temperature high-pressure saturated steam individual well metering, which is realized by a thick oil thermal production well saturated steam flow meter. The thick oil thermal production well saturated steam flow meter comprises a pressure sensor, a display, a differential pressure transmission, a V-shaped cone and a temperature sensor, wherein the pressure sensor is connected with a metering pipeline thread, the display is connected with the pressure sensor, the differential pressure transmission and a temperature sensor thread in a welding way, and the V-shaped cone is connected with the differential pressure transmission in a welding way. In the method, the thick oil thermal production well saturated steam flow meter is in threaded connection with a steam-injection well, differential pressure is generated from both ends of the V-shaped cone when steam passes through the thick oil thermal production well saturated steam flow meter, thus the thick oil thermal production well saturated steam flow metering method realizes the accurate measurement of saturated steam flow speed; the differential pressure transmission converts the saturated steam flow speed into flow signals and sends the flow signals to a computer system to display steam individual well metering at any time; and the thick oil thermal production well saturated steam flow metering method solves the problem that individual well flow can not be metered in the prior art and can be used for the thick oil thermal production steam drive steam-injection well high-temperature high-pressure saturated steam individual well metering.
Description
Technical field:
The present invention relates to the thick oil thermal extraction saturated steam flow metering method that viscous crude heating exploitation steam drive oil production, horizontal well, notes vapour well HTHP saturated vapour one-well metering are used.
Background technology:
Present Liaohe Oil Field viscous crude heating exploitation technology.Develop into steam drive oil production and horizontal wells technology from the individual well steam soak.The development of oil production technology technology and production-scale expansion will have the corresponding techniques support, and at present domestic and international existing measuring instrument does not satisfy 350 ℃, the metering condition and the measuring requirement of 17MPa HTHP saturated vapour.The steam discharge capacity of import injection boiler neither be measured, and the steam flow of filtering outlet is the steam quality that obtains by the vapor (steam) temperature of the confluent of boiler and boiler export, pressure and sample examination; Use above-mentioned parameter and calculate the saturated vapour flow.The individual well flow of annotating the vapour well is unknown, uses well head steam injecting temperature, pressure and press boiler and annotate vapour well number to convert the steam flow of individual well quite different.
Summary of the invention:
The purpose of this invention is to provide a kind of thick oil thermal extraction saturated steam flow metering method, this method has solved the existing measuring instrument that exists in the prior art and has not satisfied 350 ℃, the metering condition and the measuring requirement of 17MPa HTHP saturated vapour, and existing method of measurement can not be calculated the individual well flow; Application well head steam injecting temperature, pressure are pressed boiler and are annotated the quite different problem of steam flow that the vapour well is counted the signature individual well.
The technical solution adopted for the present invention to solve the technical problems is: a kind of thick oil thermal extraction saturated steam flow metering method, realize by the thick oil thermal extraction saturated steam flow meter, the thick oil thermal extraction saturated steam flow meter, by pressure sensor, display, differential pressure speed changer, V-type cone, temperature pick up is formed: pressure sensor is threaded with metering pipeline leading portion, display is with pressure sensor, differential pressure transmitter, temperature pick up and is threaded, and V-type cone and differential pressure transmitter are welded to connect; The V-type cone is trendy V-type internal cone type structure, and it is that the range size is measured in decision.
This method is that the thick oil thermal extraction saturated steam flow metering meter is threaded with the manifold two ends, be connected with notes vapour well, when annotating this flow meter of steam process of steam pipe remittance, produce differential pressure at the two ends of V-type cone, realized accurate measurement to the saturated vapour flow velocity, convert flow velocity to flow signal with the pressure reduction speed changer and send into computing system-display, the flow of this moment is the volume flow of standard, computing system has been obtained saturated vapour pressure value and temperature value by pressure sensor and temperature pick up, the software of computing system draws the force value of saturated vapour and temperature value and volume flow computing the volume flow of saturated vapour, and on display, show automatic record at any time, realized the one-well metering of thick oil thermal extraction HTHP saturated vapour.
The invention has the beneficial effects as follows: flowmeter structure is simple, the dependable performance accurate measurement, operation, easy to use; This invention has solved the measurement problem of thick oil thermal extraction saturated vapour under high-temperature and high-pressure conditions, for steam drive oil production and horizontal wells provide notes vapour well online in real time detection technique and method of measurement; The application of this method can refine to the pipe network evaporation capacity for engine individual well gas injection rate, for notes vapour sendout and the notes vapour effect of accurately understanding and grasping every mouthful of well provides the one-well metering data, formulates injection-production program for reasonable development scientific basis is provided.
