1.Brief introduction

Hejian Hengji Bit Manufacture Co.,Ltd is located in Hejian,Hebei province.and is Chinese bit industry's emerging enterprises.The company is mainly engaged in the development of various series of bits, development, production and sales.

Hengji company has developed and mass-produced products 3 inches to 26 inches series steel tooth bit and tricone bit, various types of PDC bits, core bit and production and processing assembly 0.6 m to 3 m large diameter drill bits.Widely used in the oil, natural gas, hydrology, address, ore drilling engineering, product marketing the country and 20 countries and regions in the world.

2.Cautions

1).Please select the applicable formation and parameters according to the instructions.

2).Carefully check the bits appearance and to check the bits threaded end face,whether the serial number on the box and certificate.

3).Selection of WOB and RPM should be within the limits of the recommended parameters, higher WOB and RPM cannot be used simultaneously.

4).Bottom hole must be clean and bit must not be used for long section reaming.

5).Drilling process must operate smoothly, find that there is Bie jump on abnormal phenomenon, should be timely analysis and take effective measures

6).The bit should be kept indoor with dry and well ventilated conditions at 10-33℃ and kept from sunshine and rain. Stored under such conditions, quality of bit is guaranteed for 3 years.
