During drilling operation, when a well kick takes place and bit bore is blocked, the by-pass valve can be opened to allow fluid circulation and well killing. Before drilling in a gas formation, the By-Pass Valve shall be located near or on the bit.
When well kick take place and pump pressure is too high or blocked, the following steps can be taken to open the By-Pass Valve :
Discharge Kelly and drop in a steel ball (or a Nylon ball) which is carried by tool;
Connect with Kelly;
Put ball into retainer by pump circulation;
When fluid is closed, the shear pin can be sheared off by adding 0.5~1.5MPa higher pump pressure than original pump pressure;
After pin is sheared, the seal sleeve move down to open the discharge hole and pump pressure come to drop down , then normal circulation and well killing operation can be started.
Petroleum exploration and development equipment refers to comprehensive equipment for oil and natural gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation Equipment, offshore drilling platform equipment, etc. and related accessories and tools; oil refining and petrochemical equipment refers to the complete set of equipment required in the whole process of oil and natural gas processing and conversion, including general equipment (such as various process compressors, expanders, etc.) , pumps and valves, etc.) and medical equipment (such as reactors, towers, heat exchange equipment, industrial furnaces, storage and transportation equipment, medical machinery, etc.). The equipment specifications and parameters of the oil refining and petrochemical industry are determined by the process of the oil refining and petrochemical industry. The oil refining and petrochemical industry is a process industry. The requirements for automation are high, and it is required to be able to run continuously and stably for a long period of time, so there are high requirements for the reliability of the equipment. The oil and gas exploration, development and production process is characterized by multiple links, complex technologies, and high individual requirements.
