Abstract
The utility model discloses a ground filter device and relates to an improved filter which is specially used for separating dispersion particles out of air or steam. The ground filter device is characterized by comprising a primary filtering device and a secondary filtering device which are connected in sequence, wherein the secondary filtering device is composed of secondary filtering devices in group A and group B. The ground filter device can meet the requirement of continuous liquid supply, can realize the impurity removal by back flushing, and meets the production requirement of deep penetrating perforations of high-pressure water jet. In addition, the ground filter device is stable in operation, meets the safety production requirement, greatly simplifies the cooperation and construction procedures, shortens the construction period, and improves the production timeliness.
Description
Technical field
The utility model relates to a kind of improved filter that dispersed granules is separated that is specifically designed to from gas or steam.
Background technology
Waterpower deep penetration system utilizes the mode of high-pressure water jet boring to form the cleaning duct, by to jet pipe, nozzle send the realization deep penetration to, form the outer turning radius of sleeve pipe and be zero miniature radially horizontal well.The ground entry well fluid appears in present high pressure water jet-flow deep penetrating perforating technology easily has mechanical acrobatics to enter into the perforation tool inner chamber, causes normally perforation construction.Enter for fear of mechanical admixture in the perforation process, usually connect the 20m oil pipe in the hydraulic perforating upper tool part, the inner screen pack of installing filters, because water jet equipment requires into well water matter standard height, under the screen pack stopping state of down-hole, can't change screen pack, cause midway that the upper lifting pipe post keeps in repair etc., can't effectively realize the hydraulic perforating construction requirement.
Summary of the invention
The utility model aim to provide a kind of safe and practical, easy and simple to handle, self prevent that entry well fluid impurity from entering into the result in blockage ground filter for installation of parts potential risk of high-pressure water jet device interior.
A kind of ground described in the utility model filter for installation is characterized in that comprising the one-level filter and the cascade filtration device that link to each other successively, and wherein the cascade filtration device is made up of secondary A group filter and secondary B group filter.
Preferably, the connection between one-level filter and the cascade filtration device is provided with valve.
More preferably, described valve is magnetic valve.
Perhaps preferably, also be provided with pressure tester in the connection between one-level filter and the cascade filtration device.
More preferably, described pressure tester is electro connecting pressure gauge.
Further preferably, described pressure tester is arranged between valve and the cascade filtration device.
The utility model can satisfy the requirement of continuous liquid supply, and backwash can reach the removal of contamination purpose, has satisfied the production needs of high pressure water jet-flow deep penetrating perforating.And it operates steadily, and meets the safety in production needs.Greatly simplify the job execution program, shortened the construction period, improved the production timeliness.
Description of drawings
Fig. 1 is the structural representation of embodiment one.
The specific embodiment
Embodiment one.
A kind of ground described in the utility model filter for installation comprises the one-level filter 1 and the cascade filtration device that link to each other successively, and wherein the cascade filtration device is made up of secondary A group filter 10 and secondary B group filter 5.Be provided with magnetic valve 2,3,12,13 and electro connecting pressure gauge 4,6,9,11 in the connection between one-level filter 1 and the cascade filtration device successively.
Entry well fluid carries out primary filter by the one-level filter, and filtration back liquid enters secondary A group filter through magnetic valve 13 and filters, and liquid enters in the well by ball valve 8 then, and this moment, magnetic valve 2,3,12 was in closed condition.When the pressure of the electro connecting pressure gauge of secondary B group filter upper end during less than the force value set, judge the plugged filter in the secondary A group filter, at this moment open magnetic valve 2 earlier, close magnetic valve 13 then, at this moment B group filter is in running order, and the water after the filtration enters in the well through filter.Want backwash secondary A set filter device, need open magnetic valve, a part of water after the filtration is oppositely discharged through magnetic valve 12 through A set filter device, treat the draining cleaning after, close magnetic valve 12, the anti-cleaning of A group filter finishes to be ready.When the electro connecting pressure gauge of secondary B group filter upper end during less than the force value set, at this moment open magnetic valve 13 earlier, close magnetic valve 2 then, at this moment A group filter is in running order, backwash secondary B set filter device, need open magnetic valve 3, a part of water after the filtration is oppositely discharged through magnetic valve 3 through A set filter device, after treating the draining cleaning, close magnetic valve 3, the anti-cleaning of B set filter device finishes to be ready.So circulation reaches the purpose of not termination of pumping feed flow work, and guaranteeing provides uninterrupted cleaning water source for the high pressure water jet-flow deep penetrating construction.
Only at filter because grunge pollution is serious, even under the situation that backwash can not be rinsed well, close one group of ball valve and magnetic valve wherein after, change standby filter, ball valve is often opened under other situations.
