Description
Technical Field
The invention relates to the technical field of oil and gas geological drilling, in particular to a method and a device for realizing divergent track deployment of adjacent vertical wells in a platform well.
Background
The development of cluster platform well is that on one operation well site or platform, several or even hundreds of wells are drilled, the well mouths of every well are spaced by less than several meters, and the well bores of every well are directionally drilled to different directions to implement predefined underground target extension. The cluster platform well generally consists of a small number of vertical wells and directional wells, and along with the development of unconventional resources, a large number of horizontal wells exist in the cluster platform well. In oil and gas field development, according to the deployment situation of a development well pattern, it is a common way to deploy relatively concentrated target sites of underground oil and gas resources on the same cluster platform in a directional well manner to complete drilling and completion operations, as shown in fig. 1. Compared with the traditional single-vertical well development mode, the mode has the technical advantages of saving ground construction investment, reducing ground land acquisition, strengthening the connection of drilling procedures and improving the operation efficiency.
However, the cluster platform is usually small in ground wellhead distance, generally between 5 and 8, and the minimum is only 2.5m. When the small-distance drilling operation is carried out, the requirements on the design of a borehole track and the anti-collision obstacle avoidance of the track are higher. When the well mouth is deployed, the distance between the designed well hole tracks of the adjacent wells on any depth plane is required to be ensured to be larger than or equal to the well mouth distance between the two wells, so that the collision and obstacle avoidance risk during drilling operation is reduced. However, in the actual process, due to the lack of design specifications and corresponding design models, the distance between the designed wellbore trajectories of the adjacent wells in a certain depth plane is smaller than the distance between the well heads of the two wells, for example, referring to fig. 2, in the design process of the trajectory of the directional wells of the vertical well and the adjacent wells in the cluster directional well, the 1# well is deployed as one vertical well, the 2# well is deployed as one directional well, and the two wells are located in the same stratum due to the underground target points, and the depths are basically similar. It can be seen from the figure that although the distance between wells at the wellhead position is 8m, after the #2 well is drilled to the deflecting section, the track is inevitably close to the track direction close to the # 1 well position because the target point of the track design is located in the southwest direction of the # 1, the track distance can be calculated to be 5.7m according to the vertical relation, and the condition that the distance between the tracks of the designed well bores of the adjacent wells in a certain depth plane is larger than or equal to the distance between the wellheads of the two wells cannot be ensured.
