Abstract
The utility model relates to an underground device for oil field exploitation and oil well production test, which comprises a water finding switch and a release joint. The utility model is composed of an upper joint (1), an upper connecting sleeve (2), springs (3, 5), a short release joint (4), a positioning ring (6), a slide ring dowel (7), a plugger (8), a cylinder body (9), a lower joint (10), a core shaft (11) and a release claw (12). The water finding device has the following advantages: (1), the obvious ground display causes the current state of the water finding device to be known clearly; (2), water finding layers can be arbitrary multiple layers, a single layer can carry out the production for a long time, and the data of pressure, liquid properties, output, etc. are accurate and reliable; (3), water finding and water pipe post blocking can be completed by one time, and a found oil layer can be exploited without installing a water blocking pipe post additionally; (4) the utility model is provided with a mechanical switch which is reliable to change directions and high in the success rate.
Description
Technical field:
The utility model relates to a kind of downhole hardware that is used for oil field development, oil well production test.
Background technology:
Along with the progress of oilfield development process, particularly adopting oilfield water outlet, the moisture continuous rising of water flooding regime exploitation is inevitable trend.Dynamic in order to monitor oil mining, find water exit accurately so that water blockoff increases oil, keep well oil output and moisture stablizing, need implement the water detection measure to oil well.At present, the on-the-spot groundwater prospecting method that adopts usually mainly is two kinds of well logging method and mechanical groundwater-tracing methods.Well logging method exist test period long, restraining factors are many, can only enroll shortcoming such as static data, are unfavorable for finding accurately in time, exactly within a short period of time water layer.When mechanical water detection, time switch is subjected to the restriction of battery electric quantity in the existing water detection instrument, and service time is short, and the hydraulic selector duty is difficult to determine, influence water detection process and effect, there are shortcomings such as the seam change switch difficulty is big, the construction success rate is low, cost height in injection well downhole flow regulator, production mandrel.
Summary of the invention:
The purpose of this utility model is the oil well down-hole water detection device that a kind of reliable operation, success rate height is provided, can accurately obtains dynamic datas such as water exit output, pressure, fluidity.
The utility model is to realize like this.Water detection device in this kind down-hole comprises water detection switch and releasing-joint two parts, wherein, the water detection switch is made up of top connection, upper joint sleeve, spring, release short circuit, locating ring, slip ring pin, blanking plug, cylinder body, lower contact, and releasing-joint is made up of mandrel and release piece.Blanking plug can move up and down in cylinder body along the track groove under releasing-joint, slip ring pin and spring action.During the water detection operation, the water detection switch sections is connected tail pipe below G.I.H, releasing-joint then is connected G.I.H with rod string.In the time of need opening switch, on carry rod string, the release piece of releasing-joint is stuck on the shoulder on blanking plug top in the water detection switch, it is up to drive blanking plug; When the slip ring pin arrives track groove top, discharge short circuit and block release piece, force in the release piece and receive, throw off blanking plug, blanking plug is descending under the effect of spring simultaneously, and the commutation of slip ring pin enters short track, open the water detection switch, realize to recover the oil, the mined bed is enrolled output, dynamic data such as moisture, be used to find accurately water exit at well head.In the time of need closing switch, on carry the beam hanger post, blanking plug is up under the effect of spring, the slip ring pin enters long track, cushion rubber can be sealed into oilhole, closes switch.
The utlity model has following advantage: (1) ground shows obviously, can know the current state of knowing the water detection device; (2) water detection layer position can be any multilayer, but the individual layer long-term production, and data such as the pressure of obtaining, fluidity, output are accurately, reliably; (3) realization water detection, water plugging string are once finished, and the oil reservoir that finds can close and adopt, and need not other water plugging string down; (4) mechanical switch, commutation is reliable, the success rate height.
Description of drawings:
Fig. 1, Fig. 2 are respectively and are water detection switch of the present utility model and releasing-joint two-part structure schematic diagram.Fig. 3 is a water detection switch blanking plug track expanded view.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of top connection 1, upper joint sleeve 2, spring 3,5, release short circuit 4, locating ring 6, slip ring pin 7, blanking plug 8, cylinder body 9, lower contact 10, mandrel 11, release piece 12, its structure, assembled relation are as follows: upper joint sleeve 2 upper and lower ends are connected with cylinder body 9 with top connection 1 with screw thread respectively, and cylinder body 9 lower ends are connected with lower contact 10; Be provided with release short circuit 4 in the upper joint sleeve 2, its upper end is connected with top connection 10, and the outside is set with spring 3, and the below is provided with spring 5; Be provided with blanking plug 8 in the spring 5 below cylinder bodies 9, blanking plug 8 upper outside are provided with locating ring 6 and slip ring pin 7, and above component-assembled constitutes the water detection switch sections; The releasing-joint part is made of the release piece 11 that mandrel 11 and setting are uniformly distributed along the circumference in the middle.Each parts of the utility model all adopt 45# carbon steel to make except that spring 3,5, and water detection switch top connection 1, lower contact 10 are processed with the TBG73 gas thread, rigid body minimum diameter 55mm.Wherein, blanking plug 8 is the cylinder that a middle part periphery protrudes, and projecting surface is provided with sealing ring.Cylinder body 9 is respectively equipped with the pipe body of external screw thread and internal thread for upper and lower end, inner headed face chromium plating, and be provided with the fork-shaped rail groove (see figure 3) that the short track of the long track of long 200mm and long 100mm constitutes, be uniformly distributed with 4 oil-feed through holes in the middle part of it along the circumference.
