The production of comprehensive mud logging equipment in China was later than that of European and American countries. In the eighties of the 20th century, comprehensive mud logging equipment in China mainly used comprehensive mud logging equipment imported from oil service companies such as the United States and Canada. The advancement of development forces and the rising prices of equipment in Europe and the United States have embarked on the road of independent entrepreneurship in the late 20s. The research factories of China’s comprehensive mud logging equipment are mainly CNPC, SINOPEC and private individuals represented by SK and IMUDLOGGING. After the research and manufacture of thesis years, the main similar products are CMS, IMUDLOGGING-3, SNOW WOLF, DML and above. The emergence of the above-mentioned comprehensive logging products means that China’s logging equipment has basically reached the international advanced level in terms of hardware, and there is a certain gap between the level of interpretation and evaluation of well-known international companies in terms of logging. Of course, there are some other brands of integrated logging products in China, but most of them are the above-mentioned OEM products, the products or quality are not high, and they have not been widely used.
Now we introduce the comprehensive mud logging products that are widely used in China.
SK-CMS Mud Logging Unit
IMUDLOGGING-3 is a comprehensive mud logging tool developed by SINOPEC. It mainly draws on equipment from Geoservice. At the same time, it has developed SinoWSL, SinoPLS-II and other multi-purpose comprehensive mud logging tools, which greatly accurately subdivides the logging service market. . IMUDLOGGING COMPANY LIMITED, as the hardware supplier of the integrated logging unit, supplied all the hardware except for the logging unit, and obtained the independent sales license for the logging unit.
IMUDLOGGING-3 is the only designated integrated logging tool of SINOPEC. In addition to all Sinopec logging services, it has entered more than 10 foreign markets including Mongolia, Iran, Kyrgyzstan, Kazakhstan, Turkmenistan, Azerbaijan, Mexico, Indonesia, Colombia and Turkey, etc. and has provided mud logging services for more than 300 wells.
Evaluation: IMUDLOGGING-3 is currently the most cost-effective comprehensive logging tool in China. It is fully certified and can be used in a variety of harsh environments (sea, desert, low temperature, etc.). The product quality is reliable and has undergone a large number of actual use tests. Recognition is a good purchase choice.
SNOW WOLF Mud Logging Unit
DMLMLU-200 Mud logging Unit
DMLMLU-2006 Dema (DML) comprehensive mud logging unit is a new product developed by China National Petroleum Corporation Bohai Drilling Engineering Co., Ltd. It mainly develops and draws on the mud logging unit of DATALOG company.
Instrument performance characteristics:
1. The overall positive pressure explosion-proof, passed the DNV A0 ZONE1 safety and explosion-proof certification;
2. Chromatographic analysis adopts µ-TCD technology, which has high analysis accuracy, short cycle and good linearity. It can analyze 9 components of C1-C5, H2 and CO2 within 30s (adjustable to 15s), which is fully adapted to rapid drilling and Need for discovery of thin-bed oil and gas;
3.32 channels of analog data, 8 channels of pulse signals, 4 channels of programmable output, which can be expanded arbitrarily;
4. Adopt isolation barrier technology, anti-interference, lightning protection, modular circuit, easy to maintain;
5. The software has rich functions, friendly interface, simple operation, and has the functions of dual hard disk data automatic backup, wireless data transmission, etc.;
6. With H2S early monitoring function.
7. The system adopts three languages: Chinese, English and Spanish, which can be switched at any time to meet the needs of different users.
8. The sensor connection adopts a patented method, which is convenient to install and disassemble, and is safe and explosion-proof
After the successful development of the instrument, nearly 100 units have been produced, which are used in Dagang, Jidong, Changqing and Indonesia markets, and are exported to Brazil, Mexico, Iran and other countries.
Evaluation: The DML integrated mud logging unit is also a piece of equipment for CNPC’s own use. The certification it has obtained does not yet meet the strict requirements for offshore logging services. Its wellsite information transmission method is relatively backward. It is a state-owned enterprise in China and is sold. Communication is relatively difficult, but in normal use, problems rarely occur.
