Description
Technical Field
The utility model relates to a gas field water storage tank filter technical field, concretely relates to gas field water storage tank embeds filter.
Background
In the current shale gas well development in China, a sand fracturing process is widely adopted in the horizontal section of the gas well, the average adding amount of fracturing sand into each well reaches thousands of tons, the existing fracturing sand mainly comprises two materials, namely quartz sand and ceramsite, wherein the particle size of the quartz sand is 70/140 meshes, and the particle size of the ceramsite sand is 40/70 meshes. Therefore, after the gas well is put into operation and produced, natural gas can carry a large amount of pressure sand and gas field water from the bottom of the well to enter a ground treatment process, and fractured sand can enter a gas field water storage tank of the cluster well station after being separated. The gas field water storage tank is used as a temporary water storage container of the cluster well station, and the gas field water storage tank is pumped to a downstream processing station through a gas field water transfer pipeline by using a water transfer centrifugal pump after reaching a certain amount.
The flow from the gas field water storage tank to the water-transferring centrifugal pump in the current cluster well station has no special filter, the inlet of the water-transferring centrifugal pump only has one Y-shaped filter of DN100 (partial well station flow has no Y-shaped filter), and the filtering precision and the filtering area are both extremely low. The water outlet of the gas field water storage tank is positioned at the bottom of the tank, and the fracturing sand is settled at the bottom and can directly enter the water transfer process when transferring water. After the fracturing sand enters the centrifugal pump, mechanical seals of the water pump are damaged, and sewage which is not tightly sealed by the water pump is discharged into the ground to pollute the environment; because the gas field water transfer pipeline lays the environment and is Chuanhuan wumeng mountain area, the mountain region is big to fluctuate, and the water transfer pipeline height difference is big, and it is many to fluctuate, can gather in the lower department of part topography after fracturing sand gets into the water transfer pipeline, lower conveying efficiency, pressure differential is carried in the pressure boost, can cause the pipeline to break under the serious superpressure condition and arouse serious environmental protection problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a built-in filter of gas field water storage tank, through mutually supporting of cast subassembly and utilize gravity type separation principle, the commentaries on classics water pump Y type filter precision that has solved the gas field water storage tank and has connected is low can't filter the technical problem that a large amount of impurity of fracturing sand gets into the commentaries on classics water piping and reduces conveying efficiency.
