ABSTRACT:. This paper takes a typical ultra-deep tight sandstone gas reservoir located in Tarim Basin as an example to investigate the rare sand production problem. The situation of sand production was presented, and then conventional analyses were conducted. As follow, six tight sandstone core plugs were selected to conduct rock mechanical tests before …

Sand control is an ongoing challenge in numerous hydrocarbon-producing wells in sand-rich reservoirs. Sand production in these wells can cause damage to equipment, reduce production rates, and lead to erosion that can damage subsea equipment, production equipment, well completions, and surface facilities. This problem can compromise the mechanical integrity …

Sand Production; The core stage of the sand production process involves further processing qualified shale particles into sand. Equipment Selection: Sand-making machines (such as impact crushers or vertical shaft impactors) are the primary equipment used for this purpose. Working Principle: Sand-making machines accelerate materials to high speeds by a high …

Well sand production can be broadly divided into two stages: the first stage is the change from skeletal sand to loose sand, which is a necessary condition leading to sand production; the second stage is the transport of loose sand. Only after these two conditions are met will large-scale sand production be caused. For the first stage of

With a larger sand production radius, the critical pressure difference will be higher. A larger sand production radius results in a lower sand production rate under a certain FBHP. Figure 5 shows the sand production rate under the FBHP of 18 MPa and sand production radii of 0.20 m, 0.22 m, 0.24 m, and 0.25 m. Overall, the possibility of sand ...
