Abstract
The utility model relates to a bottom hole pressure collection joint; the utility model solves the problem that the present down hole pressure measurement tool can not precisely master and automatically record the down hole pressure. The utility model is characterized in that the inside of a hollow identity (3) is equipped with a sensor assembly (4) and the lower part of the sensor assembly (4) is provided in a base (2); a short connection (6) and a centralizer (7) are equipped between the neck part, the middle part and the hollow identity (3); pressure holes (7) which area communicated are provided horizontally through the base (2) and the hollow identity (3); the inside of the pressure holes (7) are equipped with a pressure transmission device (1). The down hole pressure collection joint can realize the function of automatic collection and record of different well depths and different down hole pressures; the utility model has the advantage of precision and automation.
Description
Technical field:
The utility model relates to oil drilling and gathers automatic equipments of recording automatically with bottom pressure, belongs to a kind of bottom pressure and gathers joint.
Background technology:
The instrument that can measure downhole data in the oil drilling is a lot, they are sent to ground by wired mode or wireless transmission form, the process corresponding software is obtained by the professional to be decoded, but accept data, mistake appears in transfer of data and signal easily when being decoded by software, problems such as signal interruption appear sometimes, in drilling well, also do not realize at present the self registering instrument of automatic collection of bottom pressure, can't accurately grasp, calculate bottom pressure and strata pressure, especially more can't accurately grasp bottom pressure for the downhole gas liquid two-phase, operation brings very big difficulty to petroleum exploration and development.
Summary of the invention:
Existing bottom hole pressure measurement instrument can't accurately be grasped and the deficiency of automatic record bottom pressure in order to overcome, the utility model provides a kind of bottom pressure to gather joint, this bottom pressure is gathered the self registering function of the automatic collection of bottom pressure that joint can be realized different well depths, different industrial and minerals, has the characteristics of accuracy, automation.
Technical solution adopted in the utility model is: this bottom pressure is gathered joint and is comprised body, hollow body is built-in with sensor unit, and the sensor unit bottom places in the base, be equipped with short circuit and centralizer between its top and middle part and hollow body, laterally have the pressure transmission hole that communicates on base and hollow body, pressure transmission hole is built-in with pressure transfer device.
The beneficial effects of the utility model are: owing to take such scheme, this instrument is applicable in the various forms of drilling process, do not destroy original drilling assembly, can be directly installed on the drill bit, pressure transfer device will be managed outer data and will be delivered to the interior sensor unit of pipe, has the function that realizes external seal in the pipe, anti-blocking and Data transmission, base has the function that realizes external seal, drilling fluid passage, Data transmission and fixation of sensor in the pipe, and this instrument can be realized real time implementation, accuracy, the automation of bottom pressure acquisition and recording in the Process of Oil Well Drilling.
Description of drawings:
Fig. 1 is a structure half sectional view of the present utility model;
Fig. 2 is Figure 1A-A portion view.
1-pressure transfer device among the figure, 2-base, 3-hollow body, 4-sensor unit, 5-centralizer, the spacing short circuit of 6-, 7-pressure transmission hole.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this bottom pressure is gathered joint and is comprised body 3, hollow body 3 is built-in with sensor unit 4 and is used for receiving tube external and internal pressure data, 3 of sensor unit 4 tops and middle part and hollow body are equipped with short circuit 6 and centralizer 5, be used for fixing and set upright sensor unit 4, sensor unit 4 bottoms place in the base 2, base has the drilling fluid passage, the effect of Data transmission and fixation of sensor, base 2 and hollow body 3 laterally have the pressure transmission hole 7 that communicates, pressure transmission hole 7 is built-in with pressure transfer device 1, pressure transfer device 1 will be managed the external pressure data and will be delivered to the interior sensor unit 4 of pipe, realized the real time implementation of bottom pressure data acquiring and recording, accuracy, automation, and realized external seal in the pipe, the function of anti-blocking and Data transmission.This instrument can be realized the automatic acquisition and recording of bottom pressure in the Process of Oil Well Drilling, this instrument can be directly installed on the drill bit, therefore the pressure of gathering is bottom pressure, in drilling process, can realize that the bottom pressure of different well depths, different industrial and minerals automatically gathers self registering function, especially for the accurate acquisition and recording of the shaft bottom power the biphase gas and liquid flow of shaft bottom time the under balance pressure drilling, the air foam well-drilling.This instrument also can be installed in other corresponding well section of drilling tool, and the pipe external and internal pressure of this well section of acquisition and recording does not destroy original drilling assembly.
