Original Title: [Dry Goods Super Long Article] The Past and Present Life of MWD in Directional Drilling 1 Basic concepts 1. What is MWD instrument? MWD is the abbreviation of Mease oding programs. There are generally two ways to realize the coding transmitter of downhole tools. A. Drilling fluid pulse. It is equivalent to putting the hand in the water flow under the faucet,dth hammer bit, twisting the knob of the faucet, and the impact pressure on the hand will change. The  trajectory, it can only be known but not controlled, and its role is limited. Therefore, the development of measuring instruments is closely related to the development of trajectory oriented control instruments. The more advanced the directional instrument is, the stronger the controllability is,Tapered Rock Bit, and the higher the requirements for data quality including measurement frequency and accuracy are, which objectively promotes the development of i Shot", which can measure multiple data in one construction. Photographic inclinometers have been widely used in land drilling teams in recent years, and in the South China Sea, they were basically eliminated around 2014. 3. Electronic Multi Shot As the name implies, down the hole bit ,mining dth bit, the multi-point inclinometer can measure multiple points in one construction nd perature deviation. In order to enter the international market of MWD and other fields, it is difficult for domestic small and medium-sized enterprises to complete alone,dhd drill bit, which requires the state to set up projects and concentrate technology and funds to tackle key problems. Perhaps in this case, in the next 10 years, domestic products can achieve curve overtaking and occupy the international leading level.
