Abstract

On the request of the current level of the geological core drilling design, refer to oil drilling design software, a geological core drilling computer aided design system was developed by means of advanced web design technology. The system covers all procedures of geological core drilling design, and presets reference value according to system database information, and automatically draws geological column and borehole columnar section according to the user design information, and finally produces overall and standard design report. The development technology is based on ZK and Hibernate framework with MVC and MVVM model. Consequently, the system will be easy to be used and maintained, and will contribute to the geological core drilling design information exchange and share online. © 2014 The Authors.

1. Introduction

With the rapid development of computer technology, computer software is applied in all walks of life. In oil drilling industry, a lot of drilling engineering design software are developed and produce enormous economic and social benefits, and greatly drive the development of the drilling engineering. However, in core drilling industry, there isn’t the applicable geological core drilling design software. In China, the geological core drilling is still

designed by manual. The efficiency of manual design and drawing is very low. With the increasingly development of drilling technology, the manual design method can’t meet the requirements. Therefore, in order to further improve the level of geological core drilling design, the research and development on geological core drilling computer aided design is very necessary.

2. System Functions

2.1. Function Design

According to the Industry Standard of Geological Core Drilling Procedures issued by the ministry of land and resources of the People's Republic of China in 2010, and the current market demand for geological core drilling design, there are the following functions in the geological core drilling aided design system:

Design the geological core drilling design basic procedures, including geological information input, borehole columnar section design, bottom hole assembly (BHA) design, drilling parameter design, mud design, cementing design, equipment selection, accident prevention, construction organization and management, construction schedule, construction budget, and report output. Automatically plot the borehole columnar section and drilling progress chart. Real-time output the geological core drilling design report online. Import example documents. Manage the user information.

2.2. System Structure

Fig. 1 System Structure

As shown in fig. 1, the system has the database module and system functions module. Database Module

Basic information database, including geological rock database, drilling technology database, drilling equipment database, cementing database, downhole accident information, is the main basis of drilling system aided design. User information database, including the every user’s basic register information and drilling designed data. Design information database which stores each design data, is used to import and export design example and browse the design result.

System function module, which has 14 functions, will be discussed later individually.

Define and set the canvas. Import the pic_base.js file, in which there are great amounts of drawing methods compiled by the author. Draw the coordinate axes, and then fill the corresponding area with the rock legend. Draw the borehole outline, and dimension the borehole size. Draw the casing outline, and dimension the casing size. Output and save the graphic with the data stream to the specified location.

Conclusions

The paper presents a geological core drilling computer aided design system, which was developed by means of advanced web design technology. The system covers all procedures of geological core drilling design, and presets reference value according to system database information, and automatically draws geological column and borehole columnar section according to the user design information, and finally produces overall and standard design report. The development technology is based on ZK and Hibernate framework with MVC and MVVM model. Consequently, the system will be easy to be used and maintained, and will contribute to the geological core drilling design information exchange and share online. It solves the problems of manual design of the geological core drilling, low design efficiency, and lack of standardization of the drawing and design report. It significantly improves the design efficiency, shortens the design periods, and reduces the design cost. It can realize the standardization, normalization and informatization of the geological core drilling design in the whole nation. Consequently, there is a bright prospect for the geological core drilling computer aided design system.
