Abstract
The utility model relates to a pressure measuring device used to measure a drill stand/branch pipe pressure in logging process, which consists of a pressure gauge, a pressure sensor and a three-way connection which is connected with an interface of an original pressure gauge of the stand/branch pipe by one end, connected with the original pressure gauge by another end, connected with the pressure sensor by the last end. The device has the advantages of simple assemblage, convenient using, safe reliability, and high detection sensitivity, low maintain working capacity, low operating cost, widely using in pressure detection of the drill stand/branch pipe.
Description
The utility model relates to rig vertical and sleeve pipe device for pressure measurement in a kind of well logging process.
In petroleum prospecting, measuring drilling mud vertical and sleeve pipe pressure has related parameter most important to the accurate recording drilling well.At present, the device of measurement rig vertical and sleeve pipe pressure is made of isolation buffers, high-pressure oil pipe, rapid-acting coupling, pressure transducer etc.On pipe, sever an osculum, on this mouthful, connect isolation buffers, connect pressure transducer through high-pressure oil pipe then, see shown in Figure 1ly, detect vertical and sleeve pipe pressure by pressure transducer.The defective of this device is: (1) installation requirement height.Since vertical and sleeve pipe pressure big (generally have 30-40Mpa), very high to the quality requirements of welding, otherwise be prone to accidents; (2) maintenance workload is big.Easy oil leakage such as isolation buffers, rapid-acting coupling needs often to refuel, very trouble.And diaphragm stings leakage easily, needs the diaphragm that more renews after thorn leaks, and has increased maintenance workload.(3) measuring accuracy height.This inadequate natural endowment of expanding with heat and contract with cold of hydraulic oil causes sensor signal to vary with temperature and changes in the high-pressure oil pipe, makes the signal measurement distortion.Isolation buffers and oil circuit thereof are easily frozen in winter, and measurement can't be carried out.
The purpose of this utility model is to propose a kind of device that the measurement rig vertical and sleeve pipe pressure simple, easy to maintenance, that detection sensitivity is high is installed.
Rig vertical and sleeve pipe device for pressure measurement in the well logging process that the utility model proposes is made of three-way connection, tensimeter and a pressure transducer.Utilize original tensimeter and interface thereof on the rig vertical and sleeve pipe, an end of three-way connection is connected with former manometric interface on the rig vertical and sleeve pipe, an end is connected with former tensimeter, and the other end directly is connected with pressure transducer, as shown in Figure 2.
The device of the measurement rig vertical and sleeve pipe pressure that the utility model proposes is compared with classic method, and following advantage is arranged:
1, omitted isolation buffers and high-pressure oil pipe, reduced link, avoided wafing and shortcomings such as leakage of oil, oil impregnate, reduced operating cost by the caused temperature of hydraulic oil;
2, install simply, easy to use, the safety coefficient height;
3, cancelled the buffer action of isolation buffers, sensor is directly contacted with pressure medium (mud),, improved the detection sensitivity of sensor not by the pressure transmission of oil pressure oil.
Fig. 1 is former measurement mechanism diagram.
Fig. 2 is this measurement mechanism diagram.
Number in the figure is: 1 is the rig vertical and sleeve pipe, and 2 is tensimeter, and 3 are the sense force transducer, and 4 is isolation buffers, and 5 is high-pressure oil pipe, and 6 is three-way connection.
Embodiment: rig standpipe 1 overall diameter is 12cm, and the interface diameter of former tensimeter 2 is φ 20 on the tube wall, and the diameter of three joints of three-way connection 6 also is φ 20, and the joint diameter of pressure transducer 3 cooperates with the three-way connection diameter.By installation shown in Figure 2, be about to the interface on the termination standpipe 1 of above-mentioned three-way connection 6, a termination tensimeter 2, the other end directly connects pressure transducer 3, the device of promptly obtain safety, accurately, easily the rig standpipe pressure being measured.
Claims (1)
1, rig vertical and sleeve pipe device for pressure measurement in a kind of well logging process, constitute by three-way connection, tensimeter and a pressure transducer, an end that it is characterized in that three-way connection is connected with former manometric interface on the rig vertical and sleeve pipe, one end is connected with former tensimeter, and the other end directly is connected with pressure transducer.
