Utility model content
The purpose of this utility model is to provide a kind of upper oil gas field multiphase flow mixing and conveying system, the utility model has been simplified marine marginal small field and satellite oil, gas, water delivery technology, area and the weight of wellhead platform are reduced, can reduce oil field initial investment cost, realize the requirement of energy-saving and emission-reduction in offshore oil and gas field development process.
A kind of offshore oil and gas field multiphase flow mixing and conveying system provided by the utility model, it comprises a multiphase flow mixing conveying mechanism;
Described multiphase flow mixing conveying mechanism comprises Quimby pump;
The entrance of described Quimby pump is connected with offshore platform oil well, and described twin-screw delivery side of pump is connected with seabed mixed transporting tube line.
The offshore oil and gas field multiphase flow mixing and conveying system that the utility model provides, described Quimby pump can be realized the mixing of the multiphase mediums such as oil, gas, water, sand and carry, wherein can realize the supercharging of full liquid, full gas operating mode carries, be less than 60 minutes running time but need to control full gas operating mode, pumped (conveying) medium sand content should be lower than one thousandth simultaneously.
In above-mentioned multiphase flow mixing and conveying system, described Quimby pump is driven by frequency conversion explosion proof motor, can realize the adjusting of rotating speed, and meets explosion-proof requirement, and the requirement that specifically can change according to pumped (conveying) medium, realizes the adjusting of described Quimby pump rotating speed.
In above-mentioned multiphase flow mixing and conveying system, described Quimby pump is connected by shaft coupling with described frequency conversion explosion proof motor, it is emphasized that described shaft coupling need to meet the requirement of Non-spark.
The offshore oil and gas field multiphase flow mixing and conveying system that the utility model provides, mainly for the wellhead platform logistics transportation characteristics in the marginal small field in sea, satellite, substitute the mode of the difference supercharging in legacy system with the mixing mode of movement of multiphase flow supercharging simultaneously, to reduce the design scale of platform, reduce investment cost, allow more polygon border small field and satellite possess corresponding exploitation and be worth, improve the development efficiency of the energy, increase field output.
