Description
Technical field
This utility model relates to technical field of petroleum extraction, is specifically related to oil exploitation sand-proof pipe。
Background technology
Oil is the buried fluid mineral in underground。The oily liquids mineral that initial people produce nature claim oil, claim natural gas fuel gas, claim Colophonium solid combustible oil mineral。Along with going deep into that these mineral are studied, it is understood that they all belong to hydrocarbon compound on composition, in the origin cause of formation, mutual contact, is therefore referred to as oil them。The 11st WPC of nineteen eighty-three JIUYUE proposes, and oil is the complex mixture including gaseous state, liquid and solid hydrocarbon compound and a small amount of impurity composition existed in nature。So oil exploitation also includes natural gas extraction。The feature of oil exploitation is compared with general solid mineral reserve, there are three distinguishing features: the object 1. exploited constantly flows in the process of whole exploitation, oil reservoir situation constantly changes, all measures must carry out for this situation, therefore, the whole process of exploitation of oil-gas field be a continuous understanding, the process updated；2. exploitation person does not directly contact with ore body in the ordinary course of things。The exploitation of oil gas, to the understanding of situation in oil-gas reservoir and oil-gas reservoir is exerted one's influence carry out various measure, will be undertaken by special well logging；3. some feature of oil-gas reservoir must in process of production, even just must will appreciate that after well number is more, therefore, and exploration and mining phase usually mutual weave within a period of time。
Oil exploitation process needs by oil exploitation pipeline in depth under, and sand-proof pipe is as a kind of important oil exploitation pipeline, it is commonly used field of petroleum exploitation, but current sand-proof pipe uses of long duration, easily on tube wall, retain many sand grains, affect oil filter effect, it would be highly desirable to improve。
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, there is provided a kind of simple in construction, oil exploitation sand-proof pipe reasonable in design, easy to use, it is possible to dismounting sand-proof pipe internal structure at any time, carry out retaining the cleaning of sand grains, being greatly improved the filter effect of crude oil, practicality is higher。
For achieving the above object, the technical solution adopted in the utility model is: it comprises urceolus, netted inner core；The inside of urceolus is provided with netted inner core；Being uniformly provided with several fuel feed holes on the sidewall of described urceolus, fuel feed hole is provided with outer drainage screen；It is bag female thread, external screw thread, alarm and mass sensor also；The two ends up and down of described urceolus are equipped with female thread；The two ends up and down of described netted inner core are equipped with external screw thread, and it is in mating connection with female thread fixing；The upper end of described netted inner core is hollow-core construction, is internally provided with alarm and mass sensor, and alarm is connected with mass sensor。
The two ends up and down of described urceolus are equipped with fixing connecting hole, and some sections of urceolus are connected by contiguous block, and contiguous block is provided with through hole；Described contiguous block is connected fixing with its upper and lower two sections of urceolus by fixing screw, for the crude oil sucking filtration of different depth oil well。
It is provided with seal washer between some sections of described urceolus。
Operation principle of the present utility model: when the sand grains on netted inner core accumulates to a certain amount of, mass sensor senses, and controls alarm equipment alarm, and operator just can stop operation, and by rotating inner core, is disassembled by inner core, carries out sand grains cleaning。
After adopting said structure, this utility model has the beneficial effect that oil exploitation sand-proof pipe described in the utility model, sand-proof pipe internal structure can be dismantled at any time, carry out retaining the cleaning of sand grains, it is greatly improved the filter effect of crude oil, practicality is higher, and has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low。
