Mechanism analysis of geological factors on pipeline system damage. In the process of underground oil recovery, formation non-uniformity, rock characteristics, geological tectonic activity and crustal movement are objective conditions that cause damage to the production well piping system. Once these factors occur, they will be generated. Huge stress changes will damage the pipeline system in the production well and seriously affect the production of the oil field.

The sand layer in the oil layer is an important factor in the deformation and destruction of the pipeline system. The main feature of the oil layer structure in the heavy oil reservoir is the sand injection in the steam injection well. Because the heavy oil layer is mostly clay or crude oil cemented, the oil layer is very easy to be injected during steam injection. sand.
The sanding oil layer is generally a weakly cemented loose sand layer, the oil layer is loosely cemented, and the mineralized content is high. When the gas is injected, the injected hot water and steam wash the oil layer, and at the same time, the bottom bottom wet steam liquid is strongly alkaline, at high temperature. Under the action of high pressure, after several times of steam stimulation, the wettability of the rock is changed, and some rocks (feldspar and quartz, etc.) are softened, which further reduces the degree of cementation of the oil layer, especially the structure of the rock around the bottom of the well. The damage is severe, and a lot of non-cemented loose sand is formed. Then the oil flow brings the fine sand grains of these loose sandstone into the pipeline system, causing the particles to migrate during the steam injection and causing sand production.
The gas injection pressure is increased, and the temperature difference between the gas temperature and the formation becomes larger, which further aggravates the damage of the cement structure. The matrix structure changes cause the rock skeleton to break, resulting in more voids and tunnels in the sand layer. In addition, a large amount of injected steam may be pressed in the wellbore to fracture the oil layer, which may also cause sand production. In the case of eucalyptus oil, sand is generated due to the long-term action of the liquid-carrying sand on the bare hoof tube, which eventually causes stress concentration in the local pipeline system. When the thermal recovery occurs, the deformation of the pipeline system may be caused and the stress state of the pipeline system may be damaged. In-depth, regardless of whether the oil well is hot, as long as the oil layer is produced during the production process, the formation pressure cannot be replenished in time as the burst occurs, causing local stress concentration caused by the collapse of the formation.
The overburden pressure will additionally act on the pipeline system. When the pressure exceeds the compressive strength of the pipeline system, the instability of the pipeline system will occur, which will affect the life of the pipeline system and cause the pipeline system of the sand production well to be damaged in advance. According to the actual situation of the site, the investigation of the damage of the pipeline system of Liaohe Special Oil Company was mainly investigated. Most of the damage of the pipeline system occurred in the perforation section of the pipeline system, and the rest mainly occurred in the perforation section of the pipeline system, but in the pipeline system. The damage of the pipeline system above the perforation section is mainly above and below the perforation section of the pipeline system. It can be seen that the sand outflow of the oil layer affects the pipeline system damage above the perforation section of the pipeline system in the perforation section of the pipeline system. Therefore, sand production from the oil layer is one of the important factors that cause damage to the piping system.
