Description
Technical field
The utility model relates to the oil field detection technique of shaking out, particularly about a kind of sand production rate of oil field thick oil production checkout gear.
Background technology
In each oil extraction process, all extensively exist the problem of shaking out at home and abroad.Sand production rate how much be the key factor that influences the oil gas well life-span, shake out and not only cause the damage of various plant equipment, safety in production is brought major hidden danger, also seriously influenced simultaneously production efficiency.If can not control sand production rate early, may cause that oil-gas Layer sand buries, the serious consequence of oil pipe sand plug, the long-pending sand of ground line, shortened the application life of oil gas well widely, greatly to oil gas field production influence.Therefore sand production rate is detected, can control better and shake out, optimization production, the life-span of prolongation oil gas well.But the real-time monitoring of sand control, the effect of controlling sand and sand production rate then is a technical barrier both domestic and external for many years.
In existing technology, domestic research mainly is the measurement at the river silt content, does not also have the special research about the sand production rate of oil-gas well measurement, and the river silt content is measured the method that is adopted to be had: (1) ultrasonic Method for Measuring.Promptly utilize solia particle in the aqueous medium that hyperacoustic strafing with refraction effect determined silt content in the river.(2) radionetric survey method.The ray attenuation amount of utilizing χ ray or gamma-rays to pass behind the blending agent is determined silt content.(3) photoelectric method.This method depends on the interaction of light and sand grains, when light when holding the sand current under the arm because the extinction or the scattering process of silt particle make through light intensity and weaken, just can determine silt content according to the attenuation of light.(4) other method.Comprise infrared method, laser method etc.
Be used for the sand production of oil-gas wells quantity measuring method abroad and mainly contain following two kinds: (1) ray method.This kind method adopts the radioactive source of three kinds of different-energies, measures to comprise the density of sand grains at interior heterogeneous fluid, thereby determines sand production rate.(2) sonic method.Promptly, judge the sand production rate in the fluid by detecting the acoustic signal that the collision of sand grains and tube wall is produced.The probe that this method adopted has two kinds of plug-in type and externals, plug-in type is that detection probe is inserted into oil pipe inside perpendicular to tube wall, the acoustic signal that is produced with sand grains collision probe detects sand production rate, perhaps, determine the sand production rate in the multiphase flow by the damaged amount of metal of the caused probe of collision detection.External is the outer wall place that sonic sensor is installed on oil pipe, at the pipeline place of sensor installation one 90 ° turning is arranged, and this mounting means is difficult to the down-hole, in other words, is difficult to form the fluid passage at 90 ° turning in the down-hole.
The external above-mentioned two kinds of sand production rate detection methods that adopt are mainly at non-viscous crude, yet there are no report for the checkout gear of viscous crude sand production rate.Because it is big that viscous crude has a viscosity, the characteristics of mobile difference, the sand grains in the stratum is easier to be included in the viscous crude, and this brings bigger difficulty for detecting the viscous crude sand production rate.
