Abstract
The utility model discloses a ground sand control device for natural gas well is designed for preventing that oil gas pipeline from being blockked up by the gravel. A filter screen pipe for filtering sand is arranged in a separation pipeline of the sand prevention device; two ends of the separation pipeline are respectively connected with the plug and the oil-gas pipe joint, and two ends of the sand storage pipe are both connected with the plugs; the separation pipeline and the sand storage pipe are respectively arranged at the upper part and the lower part of the pipeline support; the pipeline support is internally provided with a longitudinal channel for communicating the separation pipeline with the sand storage pipe. During production, the sand prevention device is arranged at a wellhead, and sand-containing high-pressure oil gas enters a separation pipeline to filter gravel, so that clean oil gas enters a filter screen pipe and then flows into a ground production flow; the gravel falls into the sand storage pipe and is cleaned regularly. The sand control device removes sand by a physical method, can prevent the throttle valve and the manifold from being eroded by gravel, and prevents the conveying pipeline from being blocked by the gravel.
Description
Technical field
The utility model relates to a kind of ground sand control installation for the natural gas well, belongs to the natural petroleum gas field technical field.
Background technology
In the manufacturing process of petroleum gas, stratum gravel and pressure break sand grains can arrive ground with produce hydrocarbons, when reaching some, can influence production because stopping up gathering line, can damage the throttling gate valve when serious, cause security incident.
The method of gas well sand control mainly is divided into down-hole sand control and ground sand control both at home and abroad.According to sand control principle and process conditions, the down-hole sand control technique is broadly divided into mechanical sand control, chemical sand control and arch sand control etc., and the sand control emphasis is sand control in the gas well pit shaft all.And for the horizontal gas well of high yield, can pile up and the obstruction gas channel at the gas well horizontal segment from the isolated sand grains of down-hole sand control device, influence the performance of gas well deliverability.Therefore, for guaranteeing the safe high yield of horizontal well, need to adopt the ground sand control technique, carry out desanding with physical method.
Summary of the invention
The purpose of this utility model is to provide a kind of ground sand control installation for the natural gas well, and it can prevent that throttling gate valve and manifold from by the gravel erosion, preventing that feed-line from being stopped up by gravel.
Concrete technical scheme of the present utility model is as follows:
Be provided with the filter screen pipe that filters grit in this sand control installation separating pipe; The separating pipe two ends connect plug and oil gas union respectively, and the storage sand tube two ends all connect plug; Separating pipe and storage sand tube are located at the upper and lower part that pipeline supports respectively; In supporting, pipeline is provided with the vertical passage that is communicated with separating pipe and storage sand tube.
This sand control installation can prevent throttling gate valve and manifold by the gravel erosion with the physical method desanding, prevents that feed-line from being stopped up by gravel.
Description of drawings
Fig. 1 is for being used for the ground sand control installation schematic diagram of the natural gas well.
The specific embodiment
With reference to Fig. 1 embodiment of the present utility model is further specified:
Embodiment:
This sand control installation supports 4 by separating pipe 1, filter screen pipe 2, storage sand tube 3 and pipeline and forms:
Be provided with the filter screen pipe 2 that filters grit in the separating pipe 1; Separating pipe 1 two ends connect plug and oil gas union respectively, and storage sand tube 3 two ends all connect plug; Separating pipe 1 and storage sand tube 3 are located at pipeline respectively and support 4 upper and lower part; Pipeline supports and is provided with the vertical passage that is communicated with separating pipe 1 and storage sand tube 3 in 4.
During production, this device is installed in well head, not throttling of well head.After high-pressure oil gas and gravel entered this device split tunnel 1, gravel was blocked on filter screen pipe 2 outsides, and clean oil gas enters filter screen pipe 2, and entered the surface production flow process through its oil gas union.
After high-pressure oil gas and gravel entered this device, some gravels were according to self gravitation, and the vertical passage that supports in 4 along pipeline directly falls into storage sand tube 3, then is pushed into split tunnel 1 rear end by mobile oil gas by filter screen pipe 2 isolated gravels, falls into storage sand tube 3.Store up when a certain amount of when the sand amount, open the plug at storage sand tube 3 two ends, cleaning storage sand gets final product.
