Description
Technical Field
The invention relates to the technical field of petroleum drilling engineering, in particular to a programmable automatic control downlink communication device and a downlink signal transmission method.
Background
In the field of drilling engineering, various devices for measuring geological parameters and controlling the direction of a drill bit are installed underground. The ground operators in the well drilling need to know the geological condition and the well bore direction of the stratum to be drilled at any time, and continuously adjust the measurement mode and the bit direction. Thus, communication between surface operators and downhole equipment, including "up signal transmission" and "down signal transmission", has become very important.
The existing downlink signal transmission technology, such as two modes of downlink signal transmission disclosed in the background art in the document with patent application number CN 201510953355.7: in a first way, the "downstream signaling" approach is to stop and start the main mud pump in a set of time codes, and the pressure change pulses can be detected by sensors in the downhole measurement and control equipment and decoded into commands. This approach requires stopping the pump operation and downhole drilling operations, and has the disadvantages of relatively long pump-down and pump-on state determination times, low downstream signaling information, and the like. In the second mode, the drilling operation and mud circulation are the same as in the first mode. The downlink signal transmission system consists of a pipeline and a bypass valve, and the mode is that part of mud of the circulation system is directly returned to the mud tank without passing through underground measuring and controlling equipment through the opening and closing of the bypass valve. Therefore, when the bypass valve is opened and closed, the flow and the pressure at the underground measuring and controlling equipment are changed, and the codes for opening and closing the ground bypass valve are decoded through the underground sensor measurement to obtain a ground command.
