Description

Casing pressure data acquisition device seat for oil field Technical Field The utility model relates to the field of oil well data detection, in particular to a casing pressure data collector seat for an oil field. Background The pressure data measurement of the oil field is mainly that the pressure in a wellhead measuring well is used for providing reliable and key data for geological analysis of the oil field, the casing pressure needs to be measured regularly to ensure the accuracy of the data, and the measurement is frequent, and the problems exist in the current measurement process that firstly, the diameter of the measured wellhead is different in size, a measurer needs to adapt to the sizes of different wellheads during measurement, secondly, the pressure of the casing pressure cannot be observed intuitively, and the casing pressure needs to be detected frequently to determine whether the casing pressure exceeds a set value or not, so that the measurement frequency is increased. Therefore, a casing pressure data acquisition device seat for an oil field is provided. Disclosure of utility model The utility model aims to solve the problem that a measurer cannot adapt to a multi-size wellhead and casing pressure needs to be frequently detected, and provides a casing pressure data collector seat for an oil field. In order to achieve the purpose, the technical scheme is that the oil field casing pressure data acquisition device seat comprises a base, a hoop sleeved outside the base and a measuring device arranged at the top of the base, wherein the base comprises a flange plate communicated with a pipeline and a thickened expansion pipe fixed on the side wall of the flange plate in a matched mode, the measuring device comprises an acquisition device and a supporting plate arranged at the top of the thickened expansion pipe in a one-way communication mode, and the acquisition end of the acquisition device penetrates through the supporting plate and then is communicated with the inside of the thickened expansion pipe. As further description of the technical scheme, the base further comprises a plurality of screws which are uniformly distributed at the top of the thickened expansion pipe and used for fixing the thickened expansion pipe and the supporting plate. As a further description of the technical scheme, the measuring device further comprises a measuring hole formed in the supporting plate, and the inner wall of the measuring hole is in a threaded shape. As further description of the technical scheme, a pin shaft is fixed on the lower surface of the supporting plate, a movable plate which is limited to move in the pin shaft and is opened and closed within an angle range of thirty degrees is arranged in the pin shaft, and a sealing layer for plugging the measuring hole is arranged at the top of the movable plate. As a further description of the technical scheme, the detection end of the collector is threaded through the support plate and pushes the movable plate closed by pressure. As further description of the technical scheme, the hoop comprises an adjusting ring attached to the side wall of the thickened expansion pipe, an elastic device composed of a rotary threaded column and a base is arranged on the adjusting ring, and a plurality of adjusting holes which are matched with the rotary threaded column to be meshed and held tightly are uniformly formed in the adjusting ring. As a further description of the technical scheme, the thickening expansion pipe is made of rubber material with double layers of rubber and steel meshes in an interlayer mode. In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows: According to the scheme, the base is placed on the pipe diameter of the oil port needing to be measured, the adjusting ring is adjusted to be suitable for the pipe diameter of the oil port, the elastic device is screwed down, so that the base is fixed on the pipe diameter of the oil port, the base can be quickly installed on the pipe diameter of the oil port due to the elastic adjustment of the anchor ear, the installation is more convenient, and the base can be suitable for different pipe diameters of the oil port; The collector stretches into the measuring hole of seting up in the backup pad with the measuring stick to jack up the fly leaf that measuring hole one side set up, be in sealed state in the thickening expansion pipe this moment, can carry out the detection to the casing pressure, detect and pull out the measuring stick upwards, drive the fly leaf upwards to be closed, be in sealed state in the assurance thickening expansion pipe, the ring flange of base bottom prevents pressure leakage simultaneously, be in sealed state in further guaranteeing the thickening expansion pipe, whether can take place the flatulence through observing the thickening expansion pipe, thereby it is big to judge whether need measure the casing pressure data
