According to different lithology characteristics, the scale well can be further specifically divided into an open hole scale well, a glass fiber reinforced plastic casing scale well, a steel casing scale well, a glass fiber reinforced plastic casing inter-well scale well, a glass fiber reinforced plastic inter-well scale well and the like. Specifically, as shown in fig. 1, fig. 1 shows twelve experimental wells with different lithologies of J1-J12, wherein J1, J5, J9 and J11 are open hole scale wells, J6, J7 and J12 are steel casing scale wells, and J3, J4, J8 and J11 are glass reinforced plastic casing scale wells. The open hole scale well, the glass fiber reinforced plastic sleeve scale well and the steel sleeve scale well are mainly used for completing the scale and the verification of a remote detection instrument; the glass fiber reinforced plastic inter-casing well scale well is mainly used for measuring scales between nonmetallic casing wells; the steel casing inter-well scale well is mainly used for measuring scales between metal casing wells; the glass fiber reinforced plastic and steel casing inter-well scale well is mainly used for inter-well scale between nonmetallic casings and metallic casings. The lithologic material of different materials can be any one or more of glass quartz, stainless steel, cement, granite and sandy shale, and can be other materials commonly used for construction and measurement.
The method is described by taking an open-hole scale well as an example.
As shown in fig. 2, the open hole scale well is composed of a three-part structure of mud filtrate in the well, a well wall filler and the well periphery, and the well wall structure is fixed by using a solid filler material. In order to ensure that the open hole scale well can reflect a more complex downhole environment, lithologic materials with different materials are arranged at different depths of the same open hole scale well. Specifically, as shown in fig. 2, the open hole scale well is layered according to the depth dimension, and the layering is expressed as, for example: 21. 22, 23, 24 … n layers (where n is a natural number), each layer forming the open hole scale well by using lithology materials of different materials and stacking each other. In addition, lithologic materials of different materials can be arranged in different directions at the same depth of the same scale well, as shown in fig. 3, a certain depth of the naked eye scale well is split, and the split is divided along the well periphery, and the partitions are expressed as, for example: 11. 12, 13, 14, 15 … n parts (where n is a natural number), each part is filled with lithologic materials of different materials.
In addition, an abnormal body with different materials may be further disposed around the borehole wall of the barefoot scale well, as shown in fig. 4, the disposed abnormal body may be expressed as, for example: 31. 32, 33, 34, 35, 36 … n abnormal bodies (where n is a natural number), which are distributed around Yu Jingzhou.
Similarly, when the experimental well is a well with other lithology characteristics, the above arrangement may be performed, for example: fig. 5, 6 and 7 show a glass fiber reinforced plastic casing calibration well, wherein fig. 5 is a schematic diagram of the glass fiber reinforced plastic casing calibration well cut along the depth direction, and the glass fiber reinforced plastic casing calibration well is layered along the depth direction, and specifically, the layering is expressed as: 51. 52, 53, 54 … n horizons (where n is a natural number); fig. 6 is a cross-sectional view of a glass fiber reinforced plastic casing scale well of the same depth, with a certain depth of the glass fiber reinforced plastic casing scale well sectioned, and divided along the well circumference, the partitions being represented as, for example: 41. 42, 43, 44, 45 … n (where n is a natural number); FIG. 7 is a schematic diagram of a glass fiber reinforced plastic casing scale well with anomalies distributed around the circumference of the well, the anomalies provided may be represented as, for example: 61. 62, 63, 64, 65, 66 … n abnormal bodies (where n is a natural number).
It should be noted that, as an embodiment of the present invention, the interval between the wellbore wall filler disposed in the same scale well and the well Zhou Yigou is preferably not more than 35cm; and the equivalent hydrogen index of the formed scale well is-0.041-0.05; specifically, the equivalent hydrogen index of the scale well is about-0.035 when the wellbore wall packing is primarily sand shale, and about 0.015 when the wellbore wall packing is primarily stainless steel or glass quartz.
The invention provides an interwell remote detection scale device which is composed of a plurality of scale wells with different lithology characteristics. Specifically, lithologic materials with different materials are arranged at different depths of the same scale well; lithologic materials with different materials are arranged at the same deep part of the same scale well in different directions; abnormal bodies with different materials are arranged around the well wall; abnormal bodies with different materials are arranged between the adjacent scale wells.
