摘要
An electronic manometer is designed to study the formation fracturing process bya large volume of pressurized gas in an oil-well and develop a kind of fracturing tool used forthis process.It can record the pressure-time relation over the whole process.The meassure-ment error is less than 1.5% under a temperature up to 150℃ and a pressure of 200 MPa. Specially designed circiutry makes the manometer employ excellent performance under se-vere circumstances.In this paper,a novel construction of charge amplifier,an ASIC(Appli-cation Specific Integrated Circuits)and a calibration system will be discussed in detail.Thefield test results are also presented.
