Successful Cases
MDRO-011 Model and MDRO-021 Model gyro inclinometers are used in most domestic oilfields. Our products have been unanimously praised by users after application in more than 200 wells which are distributed throughout the country such as Shengli, Jianghan, Zhongyuan Engineering Company, Yumen, Turpan-Hami Drilling and Production Company, Tarim, Karamay Drilling and Production Company, Sichuan Drilling and Production Company, Jilin Drilling Engineering Company, Jilin Oil Production Company, Jilin Logging Company, and Changqing Oilfield Engineering Company. With stable performance and high accuracy, the instrument is durable and easy to use, besides, many perfomance of which are comparable with the Keeper produced by U.S. Science Drilling Company, but the price is only 1/4 of the Keeper, therfore, our product is an economic ideal choice to replace the imported automatic north seeking gyro inclinometer.

1. Application in Turpan-Hami Oilfield
The first set of MDRO-011 model gyro inclinometer put into operation in 1998 in drilling and production company of Turpan-Hami oilfield. After measuring hundreds of wells, it is proved that our product is stable and reliable and it creates a good economic benefits for the oilfield.
Shan 7-10c is a production well; there is only a small amount of water overflow after completion, no oil. Since the block is easy to ramp, it is doubt that the well trajectory is shift, thus we decided to resurvey the well trajectory of the original wells and other wells by using gyro, recognize the structure, and provide a basis for further decisions. In July 1998, it is found that the well trajectory is shift seriously, after resurvey.  通过对该井测斜,进行处理,发现该 井实钻的目底层在断层外,                                                  
Then we carried out the casing window sidetracking under the arrangement of the oil product company, the daily output is more than 30 tons after well completion,
2. Application in Xianhe Oil Production Company in Shengli Oilfield
The monitoring team of Xianhe oil Production Company in Shengli oilfield compared two kinds of homemade gyro inclinometers by carrying out the operation in the deep wells with high temperature and found that the MDRO-021 Model gyro inclinometer has better resistance to high temperature, faster measuring speed, more accurate data and more stable performance.
3. Application in Zhongyuan Oilfield
Gyro inclination survey, casing window and gyro directional technology is widely used in Zhongyuan oilfield. Good results have been achieved in the No.5 oil production company, No.2 oil Production Company and drilling company by using the gyro inclinometer to resurvy the well trajectory, cut window, directional sidetrack the old wells. The first half of 2003, more than 30 wells have been measured by our products, which saved more than 80 million RMB investments for oil Production Company.
4. Application in Jianghan Oilfield
Our company has provided twice technical service for Jianghan Oilfield in September 2002 and July 2003 respectively, and a total of seven wells has been measured (Wangxin 66, Wangbei11-7, Wang 76 Xie-4, Wang 63-6, Ma 55, Ma 55 Xie- 2, Huang 22 Xie-2), since the process of the on-site construction is smooth, the measurement data is accurate and reliable, material interpretation system is perfect, we have been highly praised by the First Party.
Wang 76 Xie-4 is a production well of Jianghan oil production company. To meet the demands of geological structure reorganization, the gyro inclinometer was used to retest the well trajectory. Since the well is deep (required depth is 3389.50 meters), with larger inclination and higher temperature gradient, therefore the performance of the instrument such as high temperature resistant and anti-pressure can be verified. After measuring the whole well according to the requirements, the measured maximum temperature and the maximum inclination are 121.0 ℃ and 46.7 ° /2795m. The process is smooth, the measurement data is accurate and reliable, and it is proved that the high temperature resistant of the instrument is highly reliable
5. Application in Xinjiang Tarim Oilfield
Till the end of 2004, in the Tarim region, seven ultra deep well named T-417, T-433, LG-40C, etc have been carried out measurement by the gyro inclinometer. The LG-40C is located in Lungu oilfield, and the design depth of the well is 6,500 meters (5920m of measured depth). The instrument displayed that the temperature reached 136oC, over 125oC indicator temperature when doing gyroscopic survey and whipstock orientation. The process of the on-site construction is smooth, the measurement data is accurate and reliable, gyroscopic survey and whipstock orientation have been successfully completed.
6. Application in Chuandong Drilling and Exploration Company in Sichuan Province
After the purchase of MDRO-021 Model gyro inclinometer, Chuandong Drilling and Exploration Company in Sichuan Province have measured more than 30 wells, including well trajectory measurement, cutting window and whipstock orientation, all of which were successfully completed, provided accurate data for the next step and obtained customer praise.
35 wells: (Sichuan No.8 team) "data is accurate and performance is reliable":
Mud: density 2.01, viscosity 53S, shear force1.5/5.5pa
Drilling tools:8-1/2SH33G roller bit, +430*410 cement valve +6-1/2 drill collar +215 centralizer +6-1/4 drill collar + 5" drill pipe
Depth: 4230 m
7. Application in Jilin Oilfield
In Jilin oilfield, more than 60 wells were measured after the branch companies such as drilling engineering company, well logging companies, and oil production company purchase gyro inclinometer, including well trajectory measurement, cutting window, whipstock orientation, and oriented perforation, all of which were successfully completed, provided accurate data for the next step and obtained customer praise, especially in the operations of block reorganization, infill well arrangement.
In addition, MDRO series gyro inclinometer also used in the oil, salt, and mine  distriduted in north China oilfield, Liaohe oilfield, Daqing oilfield, Dagang, Xinjiang, Changqing oil field, Sichuan salt companies including well trajectory measurement, and whipstock orientation. With stable performance and high accuracy, the instrument is durable and easy to use, and provides a reliable guarantee of quality projects and save a lot of money. Our products have been unanimously praised by users.
