Title: Innovations of Songyan Li in Carbon Dioxide Control Technologies
Introduction
Songyan Li is a prominent inventor based in Qingdao, China. He has made significant contributions to the field of carbon dioxide control technologies, holding a total of 4 patents. His work focuses on innovative methods and devices that enhance the efficiency of carbon dioxide usage in various applications.
Latest Patents
One of his latest patents is a carbon dioxide fluidity control device and method. This device comprises a sample preparation tank, a high-pressure stirring unit, a reciprocating plunger pump, and a booster pump. The stirring unit includes one or more high-pressure stirring tanks, each equipped with an atomizing spray probe and a piston. The discharge port of the sample preparation tank connects to the atomizing spray probe via a plunger pump, which pushes the piston to reciprocate. The booster pump supplies supercritical carbon dioxide to the high-pressure stirring tanks, with a discharge port connected to an oilfield well group. The method involves mixing surfactants and nanoparticles with heated carbon dioxide and injecting a microemulsion of supercritical carbon dioxide and nano-silicon dioxide into an oilfield well group.
Another notable patent is a method for integral profile control and plugging of water encroachment and steam channeling in heavy oil reservoirs with edge and bottom water. This method includes selecting an oil reservoir, arranging a huff-puff well, performing steam huff-puff development, and executing integral plugging control. The technology employs a high-strength nitrogen foam system injected at various positions in the oil reservoir to form effective plugging walls, thereby reducing water invasion and steam channeling.
