Background
Inclinometers are indispensable tools in drilling engineering, and are mainly divided into electronic inclinometers and mechanical inclinometers. Because the underground conditions are complex and changeable, the mechanical inclinometer has the advantage of higher working reliability when facing severe working conditions such as high temperature, high pressure and the like.
The mechanical inclinometer has various structures, and a representative inclinometer scheme comprises a mechanical wireless inclinometer disclosed in China patent application No. CN200510042035.2, and a mud pulse signal generating device and an inclinometer disclosed in China patent application No. CN 202210516750.9. The inclinometer senses the well inclination angle by using the gravity of a pure mechanical structure, and uses mud as a signal transmission medium to communicate with the ground. Among the two schemes respectively disclosed in the above two patents, the latter scheme has the advantages of large inclinometry range and no need of stopping the pump in the inclinometry operation process.
In the inclinometer disclosed in the above application number CN202210516750.9, the device for specifically sensing the well inclination angle is a flow control valve comprising a bias block, and the bias block is fixedly connected with a flow distribution valve core contained in the flow control valve to drive the flow distribution valve core to rotate relative to the flow distribution valve seat, so as to realize the regulation and control of the flow control valve. The flow output by the flow control valve is related to the sensed well deviation, and the real-time well deviation angle can be judged and identified according to the flow of drilling fluid output by the valve.
Disclosure of Invention
However, in the prior art represented by the inclinometer disclosed in CN202210516750.9, the eccentric weight block for sensing the well inclination angle is directly exposed in the flow channel, and besides the eccentric weight block is subjected to the action of gravity, the eccentric weight block is also directly impacted by drilling fluid, so that the stress is complex, and the eccentric weight block is difficult to keep stable during inclinometry. Therefore, the gravity sensing regulating valve for well deviation measurement has the advantage of stable well deviation measurement process, and the problem is solved by the following technical points:
the gravity sensing regulating valve for well deviation measurement comprises a valve body with a valve body fluid inlet and a valve body fluid outlet, wherein a flow passage for communicating the valve body fluid inlet and the valve body fluid outlet is arranged in the valve body, and a valve seat and a valve core capable of rotating relative to the valve seat are fixedly arranged in the valve body; the valve body is internally provided with a eccentric weight block accommodating cavity, the eccentric weight block accommodating cavity is airtight, an eccentric weight block is arranged in the eccentric weight block accommodating cavity and can rotate relative to the valve body, the rotation center of the eccentric weight block is coaxial with the rotation center of the valve core, and the eccentric weight block is fixedly connected with the valve core; when the valve body is tilted: the eccentric weight block can drive the valve core to rotate relative to the valve seat.
As described above, the present utility model provides a gravity-sensing regulator valve for well deviation measurement, in general, the valve body of the present regulator valve has or is mounted with a valve body fluid inlet, a flow passage, a valve seat, a valve element, and a valve body fluid outlet, the valve element being rotated relative to the valve seat to regulate the opening degree of the present regulator valve. Simultaneously, rotary valve core and eccentric weight piece fixed connection, under the effect of eccentric moment of eccentric weight piece, the eccentric weight piece drives the valve core and points to the gravity direction all the time, and this gravity sensing governing valve installs on the drilling tool after, and the valve body can incline with the drilling tool jointly. When the valve body, namely the drilling tool, inclines, the valve core always pointing to the gravity direction can rotate relative to the valve body, and then flow regulation is achieved. The flow output by the fluid outlet of the valve body is regulated and controlled by the valve core, and the rotation of the valve core is controlled by the eccentric weight, so that the real-time well inclination angle is reflected by the flow output by the regulation and control device, the effect of measuring well inclination is realized, and the valve core adopts a rotary valve, such as a ball valve or a butterfly valve. Unlike available technology, the valve has also one sealed eccentric weight holding cavity inside the valve body, and the eccentric weight is set inside the holding cavity and deflected inside the holding cavity. Because the eccentric weight accommodation cavity is airtight, the eccentric weight cannot be impacted by drilling fluid when rotating, and can swing freely only under the action of gravity, so that the induction of well deviation is more stable. The gravity sensing regulating valve for well inclination measurement has the advantage of stable inclination measuring process, and the mechanical inclinometer provided by the utility model can output an inclination measuring signal with higher quality than the prior art.

The characteristic provides a specific implementation mode of the regulating valve, namely, the valve body comprises an upper valve body and a lower valve body, and the two valve bodies are enclosed to form a cylindrical valve seat and clamp a cylindrical valve core. The upper valve body and the lower valve body can be connected through bolts so as to facilitate the assembly and disassembly of the valve core in the valve body. The valve core rotates in the valve seat to adjust the superposition area between the valve core fluid inlet and the valve body fluid inlet, thereby changing the size of the fluid flow area so as to realize the effect of flow adjustment. The fluid medium with specific flow rate and with specific flow rate flowing in from the superposition part of the valve core fluid inlet and the valve body fluid inlet then enters a flow passage formed by the interval between the two sealing end surfaces and flows out from the valve core fluid outlet and the valve body fluid outlet. The sealing end face and the sealing cylindrical surface prescribe the flow direction of the slurry, so that the slurry is prevented from flowing to other areas in the valve body, and the slurry is prevented from interfering the work of the eccentric weight.

The characteristic is that the flow inlet of the valve body is opposite to the flow outlet of the valve body, and the flow directly flows out from the outlet without changing the flow direction after flowing into the flow channel from the inlet. The specific position between the inlet and the outlet makes the regulating valve have the advantage of small flow resistance.

The characteristic provides an implementation mode of the valve core fluid inlet, and the step arrangement of the four valve ports means that the four valve ports are connected end to end, no matter how much angle the valve core rotates in the adjusting range, the valve core fluid inlet and the valve body fluid inlet are all overlapped, and the measuring process is not interrupted. The stepped arrangement also means that the four valve ports are not collinear in a staggered manner in the axial direction of the sealing cylindrical surface, different valve ports are overlapped with the valve body fluid inlet under different rotation angles, the widths of the four valve ports are different, and the overlapped areas of the valve core fluid inlet and the valve body fluid inlet under different rotation angles are also different, so that the flow regulation effect is realized.
In order to enable the device to perform measurement work in a well deviation range of 0-90 degrees, the device is provided with: the rotary shaft of the valve core is taken as the center: the circumferential angle between the top edge of the first valve port and the bottom edge of the fourth valve port is 90 degrees.
The valve core fluid outlet completely covers the valve body fluid outlet, and takes the rotation shaft of the valve core as the center: the peripheral angle between the top and bottom edges of the spool fluid outlet is 90 deg.. The characteristic is that in the inclinometry process, the superposition area of the valve core fluid outlet and the valve body fluid outlet is kept unchanged, the flow outlet part does not regulate the flow, and the regulating valve only adopts the valve core fluid inlet and the valve body fluid inlet to play a role of flow regulation. The regulating valve is simple and easy to control for regulating the flow.
