Comprehensive logging instrument is an important equipment for real-time monitoring in oil drilling field. It plays an important role in timely discovery and rapid evaluation of oil and gas reservoirs, safety assurance of drilling construction, reduction and reduction of personal damage. With the increase of drilling depth and speed, the performance requirements of comprehensive logging instrument are higher and higher. At present, the core technology of comprehensive logging instrument in China has reached a high level, and its cost performance advantage is obvious, about 1 / 2-2 / 3 of the price of similar products in foreign countries. With the increase of domestic crude oil production and natural gas production, the number of drilling wells will continue to increase.

To sum up, with the gradual recovery of the economy and the stabilization and recovery of crude oil price demand, it is expected that the demand for domestic comprehensive logging instruments, blowout preventers and other drilling equipment will rise steadily, and may increase significantly in 2010. We suggest to pay attention to Shenkai (25.59,0.10,0.39%) which is strengthening the integrated development and production of petroleum equipment in China. With the raising investment project put into production, the company may achieve rapid development by virtue of market brand effect and strong R & D ability.
