Oil exploration tension combination pressure base pedestal

Abstract

The invention provides an oil exploration tension combination pressure base pedestal, and belongs to the technical field of oil exploration. The oil exploration tension combination pressure base pedestal structurally comprises a base and an oil tank. An oil injection port and a sensor interface are formed in the front side of the oil tank. An unimpeded telescopic oil pressure telescopic sleeve cylinder is arranged at the center of the top surface of the oil tank. A high plastic strain column is arranged in a space, extending from the bottom of the oil cavity to the top end of an upper cavity of the oil pressure telescopic sleeve cylinder, of the middle of an oil cavity. A bearing block is fixedly connected with the upper surface of a penetrating pressing plate on the upper portion of a spherical bearing seat and used for withstanding pressure of external force. A pulling force supporting rod is arranged on a base of the side direction of one side of the oil tank. A pulling ring is fixedly connected with the upper surface of the end part of the tensile end of a penetrating and pressing plate. A spacing distance exists between the pulling ring and a valve hole. By means of the oil exploration tension combination pressure base pedestal, the quality and standard of comprehensive logging construction are improved in the field application, the accuracy and timeliness of pressure detection are improved, and the running benefit of equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration, in particular to an oil exploration tension-compression combined pressure base pedestal. Background technique [0002] Integrated mud logging technology is widely used in the drilling process of oil and gas exploration. Comprehensive mud logging is not only widely used in parameter wells, pre-exploration wells and exploration wells in the exploration process of new areas, but also has a very obvious effect on the construction of development wells and adjustment wells in the development process of old areas. Since the comprehensive mud logging technology is a high-tech aggregate of multidisciplinary and multi-technical integration, the large number of parameters and data information it obtains at the construction site is not just for a single user, that is to say, the obtained drilling engineering information can be used for It can be used by drilling engineers and technicians, and ...

Problems solved by technology

The method of comprehensive mud logging to detect the rotational torque of the drilling rig is through the direct vertical compressive stress and the current intensity of the electromagnetic field. However, how to vertically transform, utilize and analyze the detection of torque and tension is a key technology. problem

At present, the methods of torque detection mainly include mechanical hydraulic torque, jackscrew torque, electric torque and induction disc torque, but the detection principle is single and cannot be combined and applied. In short, there are many ways and methods of torque or tension detection. question:

[0006] (1) The detection method is single and the pressure transmission is not perfect;

[0007] (2) The lack of a pressure conversion device complicates the simple problem;

[0008] (3) Transitional physical exertion is caused during the installation of the hydraulic torque detection device for chain transmission, which is not conducive to occupational health protection, and the transmission mode is unsafe;

[0009] (4) The installation of the jacking screw torque device is complicated, which affects the cross operation;

[0010] (5) Inductive chip torque detection has high requirements on the applicability of the environment, and there are many factors affecting the detection;

[0011] (6) Electric torque is only suitable for electric drive and cannot meet the detection needs of mechanical torque;

[0012] (7) The installation position is fixed, lacking random selectivity
