Description

Technical Field

[0001] The invention relates to a drilling measurement tool in the field of oil drilling, in particular to a high-side positioning tool for a directional well or a horizontal well power drilling tool. Background Art

[0002] As a drilling tool, power drilling tools have been widely used in the construction of complex wells such as directional wells and horizontal wells. They can not only control the wellbore trajectory to achieve the purpose of construction, but also effectively improve the drilling efficiency, which is beneficial to the exploration and development of unconventional oil and gas reservoirs and increase oil and gas production. The energy conversion of drilling fluid is used to increase the drill bit speed, which is beneficial to increase the mechanical drilling speed. Due to the mature technology of this tool, it has been widely used at drilling construction sites.

[0003] In order to more accurately measure the angular difference between the instrument and the power drill before construction during the drilling process, it is necessary to make a mark at the bypass valve of the power drill that is the same as the high side position. At present, the most primitive visual method is still used to calibrate the mark on site. This method requires the power drill to be rotated and fixed so that the position of the engraved line can be visually observed, which causes a large error in the precise measurement work, and may even cause serious consequences and be dangerous.

[0004] In order to ensure the positioning of the high side mark at the bypass valve of the power drill after the repair is confirmed on site or there is no high side mark at the bypass valve, and to complete the high side positioning of the power drill accurately and safely by one person, a safe, accurate and simple high side positioning tool for the power drill is necessary. At present, the high side positioning tool for the power drill has the disadvantages of low accuracy, complex measurement operation and high risk factor. In order to ensure the smooth implementation of the high side positioning on the power drill, there must be a simple, effective and safe positioning device that can meet the positioning of the high side. Summary of the invention

[0005] The purpose of the present invention is to provide a directional well and horizontal well power drilling tool high side locator with simple structure, accurate measurement, high efficiency, simple operation and safety and reliability in view of the problems existing in the prior art. The high side locator is used to locate the high side mark at the bypass valve of the power drilling tool after on-site repair or when there is no high side mark at the bypass valve, so as to provide accurate high side for the angular difference measurement of the directional well.
