Abstract
The utility model relates to a while-drilling vertical well inclinometer constituted by a down hole part and a ground part. The down hole part comprises a battery short section, a pulser short section and a drilling tool joint, which are threadedly connected together in a top-to-bottom arrangement. The ground part comprises a mud pump pressure sensor, a ground main machine, and a data processing software. The pulser short section of the down hole part comprises an inclination survey circuit, which is constituted by an acceleration transducer provided with two or more shafts, besides, a chip adopts a resistance grade of high temperature of 175DEG. The working sequence of the pulser short section of the down hole instrument is programmable, and can be set to be closed in a time-delay manner or opened at a fixed time by the data processing software in order to save power. The while-drilling vertical well inclinometer provided in the utility model has advantages of simple structure, convenient operation, while-drilling measurement, more than 0.1degree measurement precision, abilities of measuring parameters such as temperature, gravity high side and so on, thereby solving the technical problems of the while-drilling vertical well inclinometer of deep wells, ultra-deep wells, high-temperature high-pressure wells, which are specially difficult, improving drilling efficiency, and saving drilling costs.
Description
Technical field
The utility model belongs to drilling engineering field in oil, colliery and the geological prospecting, be a kind of be used for that drilling process hole deviation attitude parameter measures with boring the deviational survey instrument.
Background technology
At present, the mechanical type directional tool efficiently solves straight well in the present drilling engineering with the technical barrier that bores deviational survey, particularly hp-ht well, deep-well, ultradeep well deviational survey in the known wellbore construction.But this inclinometer certainty of measurement is low only to be 0.5 ° and 1 °, the directional survey scope: during 0.5 ° of certainty of measurement 0 °～5 °; When certainty of measurement is 1 °, 0 °～10 °, through manual adjustment; Its pendulum adopts " go up and hang " location, the tapered extension of locating snap ring, and the angle of pendulum center line and centre line equals hole angle all the time; Angle changes greatly; Unitary construction is complicated, and parameter such as energy measurement temperature, gravity flash not, and in use the slush pump discharge capacity is had relatively high expectations.
Summary of the invention
In order to solve the problem that Purely mechanical directional tool certainty of measurement is low, measurement parameter is few; It is a kind of with the drilling straight-hole inclinometer that the utility model provides; Use the directional survey precision can reach more than 0.1 ° under high temperature, the hyperbaric environment, and can measure parameters such as temperature and gravity flash.
The utility model solves the technical scheme that its technical problem adopted: be made up of down-hole part and above ground portion with the drilling straight-hole inclinometer; The down-hole part comprises battery pipe nipple, pulser pipe nipple and tool joint; Be threaded from top to bottom, above ground portion comprises slush pump pressure sensor and ground host.Comprise the deviational survey circuit in the pulser pipe nipple of down-hole part, the deviational survey circuit is become by diaxon and above groups of acceleration sensors, and chip all adopts anti-175 ° of high-temperature levels.The work schedule of the pulser pipe nipple of downhole instrument is able to programme, is set to time-delay closing or regular the unlatching with power saving through data processing software.At first carry out the work schedule setting, connect the downhole instrument assembly then, be fixed in the directed interior cover of drill collar joint, transfer to the down-hole with data processing software paired pulses device pipe nipple.When slush pump quits work; Downhole instrument is operated in the measurement state and data measured is stored; When slush pump starts and reach certain discharge capacity; The pulser startup work of downhole instrument transfers to ground through mud with pulse signal, reacts pulse signal on the slush pump pressure sensor on ground.Ground host is scaled parameters such as hole deviation, gravity flash and temperature according to coding protocol with the pulse signal variation.
The beneficial effect of the utility model is: product structure is simple, easy to operate; But measurement while drilling; Certainty of measurement can reach more than 0.1 °, and can measure parameters such as temperature, gravity flash, has solved special highly difficult straight wells such as deep-well, ultradeep well, hp-ht well with the technical barrier that bores deviational survey; Improve drilling efficiency, practice thrift drilling cost.

The specific embodiment
As shown in Figure 1, the down-hole part comprises battery pipe nipple (1), pulser pipe nipple (2) and tool joint (4), is threaded from top to bottom.Above ground portion comprises pressure sensor as shown in Figure 2 (6), and the PC (9) of ground as shown in Figure 3 main frame (8), band data processing software is communicated by letter through embedded radio receiving transmitting module realization between pressure sensor (6) and the ground host (8).
At first use data processing software paired pulses device pipe nipple (2) to carry out the work schedule setting, connect the downhole instrument assembly then, be fixed in the directed interior cover (3) of drill collar joint (5), transfer to the down-hole.When slush pump quits work; Downhole instrument is operated in the measurement state and data measured is stored; When slush pump starts and reach certain discharge capacity; Pulser pipe nipple (2) the startup work of downhole instrument transfers to ground through mud with pulse signal, and the slush pump pressure sensor (6) on ground is gone up the reaction pulse signal.Ground host (8) is scaled parameters such as hole deviation, gravity flash and temperature according to coding protocol with the pulse signal variation.
More than the utility model case study on implementation has been carried out detailed introduction, and set forth the concrete case method of the specific embodiment in actual use, the explanation of above examples of implementation just is used to help to understand the using system of the inventive method; Simultaneously, for one of ordinary skill in the art, according to the thought of the inventive method, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction that invention is used to this method.
