2013Year12month5Japanese CCTV News Channel reported that “oil pollution destroys cultivated land”、“Extension of illegal petroleum land use for many years”、"'Temporary'10The land use procedures for 2016 have been delayed” and other content reported that the temporary land use procedures for petroleum land have been extended beyond the expiration date、Land pollution and other issues。

2014Year3month14Vice Governor of Rizhuang Changxing held a special meeting on the treatment of oil and gas production land of Yanchang Petroleum Group，Request to resolve the historical issues of extending oil and gas land use。4Month Shaanxi Yanchang Petroleum (Group) dafabet mobile loginentrusted the group company to complete the survey and demarcation of Shaanxi Yanchang Petroleum land。

Refer to the spirit of Governor Zhuang’s meeting，Changqing Oilfield Company、Yan'an Oil and Gas Company、China Petrochemical Corporation entrusted the Group Surveying, Planning and Design Institute to complete its company boundary survey and approval work。

2. Project scale

Oil and gas production land demarcation and approval project，Involving four oil and gas land companies including Shaanxi Yanchang Petroleum (Group)，and its subordinate units48, the land covers Yulin, Yan'an, Xianyang, and Tongchuan4City28County (district), connect with relevant units80More than one.2014Year,2015Completed field boundary survey in two years510,0006Thousands of cases, land application area30.38Ten thousand acres.

3. Project results

Project since2014Year5The field boundary demarcation work started in January2015Year5The month is completely over，Obtained through full field data collection5.6Land boundary data of 10,000 well sites, formed5.6More than 10,000 "Field Investigation Registration Forms". Adopted within the projectArcgisSoftware for data management and database creation46pieces, drawn1:2000Survey and Boundary Map Approx.5More than 10,000 sheets, the number of printed boundary address and fruit lists20More than 10,000 sheets, forming a total boundary demarcation report41Department, Division255Book binding.

4. Technological Innovation

1, Application of new measurement technology

This project has scattered operating points，The area of ​​a single mapping unit (well site) is small，Tight construction schedule and other actual conditions。Using traditional wire measurement technology and staticGPSThe technical workload is too heavy、Take too long、Accuracy is difficult to guarantee、Problems such as poor scalability。

During the project implementation process, we adopted a brand newCORSStation technology has been deployed in Yan'an and Yulin8temporaryCORSStation, calculates parameters by county and region, operates around the clockCORSSite releaseGPSPositioning parameters，Provides accurate information for project implementation、Efficient basic control。

2, research and development of internal processing and quality inspection procedures

This project involves approx.510,000 survey and boundary maps，Use manual framing、Print operation，will be needed10Desk plotter continuous3Months of work can be completed. In this project we combine.net、ArcEnginePlatform, adoptedC#The automatic frame drawing program is written in the language, and will3Month’s workload reduced to10About days.

Cumulative projects involved3427Administrative villages,5.610,000 well sites,5.2approximately 10,000 plots38710,000 sets of coordinate data，Using manual entry of boundary demarcation classification area、Boundary address point result data，Accuracy and construction time requirements cannot be guaranteed。Two difficulties in internal processing，We are in softwareMDBBased on the database, usingC#Language has developed a batch entry program for classification area and boundary point results、Boundary address point result is reversedSHPTopology Checker。Two programs improve work efficiency，Data quality ensured，Played an escort role in the processing of boundary demarcation and approval data。

4. Technological Innovation

Due to the Xi’an Railway Bureau’s railway land surveying and registration agency project involving many lines、Heavy work tasks、Tight construction time，In addition, the railway itself is a linear feature，Using traditional measurement methods can no longer meet the requirements。Therefore，This project introduces photogrammetry technology，Aerial surveying using drones，GetDOM, extract relevant information and produceDLGProduct。This method greatly saves time and cost，Ensuring the production schedule for railway maps，Meet the accuracy requirements for line center line mileage recovery。

Project Outlook

Through Northern Shaanxi Oil and Gas Production Enterprise2014Implementation of land demarcation and approval projects left over from years ago，The computing service center has mastered the well location distribution of four oil production companies including Yanchang Petroleum Group in northern Shaanxi、Road traffic、Basic information such as land use。Accuracy of data、Comprehensiveness、Reality is unprecedented for oil and gas production companies。We have the idea to build an "oil well information management platform" for oil and gas production companies in the future，Assist enterprises to manage land，Manage production and operation work through the platform，And guide the company’s subsequent production dafabet loginand development decisions。

The successful implementation of the railway land registration, certification, cadastral surveying, mapping and title confirmation project，We have obtained the spatial location information of all railway lines and important ancillary facilities in the province under the name of Xi'an Railway Bureau。We will consider the railway management and operation needs of the Railway Bureau，Establishing a "Railway Information Management Platform"，For railway maintenance、Maintenance、Increase (expand) construction, maintenance and provision of systems、Queryable basic data information。

Followup，We will summarize the successful experience of two major projects，Relying on industry、Technology、Talent advantages，Strive to provide communication within the province、High Speed、Electricity、The land information supervision platform for large state-owned enterprises such as agriculture provides high-quality services。Formation of relevant industry big data collection，Provide data support for provincial economic development decisions。
