Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard is based on the important technical content of DZ/T 0054-1993 "Directional Drilling Technical Specifications", the name and chapter of the standard.
The structure of the section, the technical content of the chapter and the contents of the attachment were supplemented and revised. Compared with DZ/T 0054-1993, except for editorial changes
The main technical changes are as follows.
--- The name of the standard was changed to "Directive Drilling Technical Regulations";
--- Added structural content such as "preface", "item" and "references";
--- Added "normative reference documents", "special directional hole drilling", "directional hole trajectory control", "directional drilling measurement and trajectory calculation", etc.
Chapters and technical modifications to the text layout;
---Selection of directional drilling design, directional drilling equipment and equipment, directional drilling construction technology, prevention of directional drilling accidents and
The chapters have been revised considerably;
--- Removed some of the technology is too old and inappropriate, supplemented with new equipment, new appliances, new technologies and new processes;
--- Removed the recommended mud pump, continuous whipstock and hydraulic bottom hole power drill in "Selection of Directional Drilling Equipment and Appliances"
With the parameter list; supplement the slanting drilling slanting record table, the final hole acceptance measurement record table and the directional hole axis trajectory coordinate calculation table
And other forms;
--- Added two appendices for "orientation tool angle-oriented calculation formula" and "orientation hole axis trajectory calculation method".
This standard was proposed by the Ministry of Land and Resources of the People's Republic of China.
This standard is under the jurisdiction of the National Land Resources Standardization Technical Committee (SAC/TC93).
This standard was drafted. Institute of Exploration Technology, Chinese Academy of Geological Sciences.

Language and definition, and supplement and improve.
3.1
Directional drilling directionalborehole
Using the natural bending law of the borehole or using an artificial slanting tool to make the borehole bend, forcing the axis of the borehole to extend according to the design trajectory
a method of drilling.
3.2
Primary directional hole preliminarydirectionalborehole
Using conventional techniques and techniques, the directional holes that are naturally inclined and regularly formed by the formation are utilized.
3.3
Controlled directional hole controlleddirectionalborehole
A boring machine and process measures are used to drill the borehole axis along the design trajectory.
3.4
Main hole mainborehole
The borehole axis is the borehole that is first designed and constructed.
3.5
Branch hole branchborehole
A directional hole that branches off from the main hole.
3.6
Horizontal directional hole horizontalborehole
The borehole end hole axis is close to the horizontal directional hole.
