Abstract

In the drilling process, there are several phases: open hole and close hole. Open hole stage is drilled to create holes and then measured in three-dimensional shape of land. While the close hole stage is a reservoir that have been made, coated with concrete is known cementing. In this final project will discuss the form of wall surface of cementing (close holes). This system uses ultrasonic sensors with 42 KHz of frequency as a detector layer of concrete walls, a rotary sensor for measuring the depth of the hole drilling and facilities of the microcontroller as the main controller circuit. Data from scanning is data pulses to be processed by a microcontroller, and then it is sent to the computer by serial communications and display in three dimensions. To display the form of a layer of concrete walls in three dimensions, the y-axis is assumed as the depth of well. As for the x-axis and z-axis are sought by the formula geometry obtained from the combination of TOF ultrasonic and servo angle. The expectation target is to know the shape of the surface layer of concrete from the reservoir is detected by the ultrasonic sensors. Surfer is software used to display three-dimensional surface layer of concrete.
