Description
Technical field
The present invention relates to oil drilling and logging technique field, particularly relate to brill density log technology.Specifically a kind of measurement while-drilling instrument of the density of earth formations based on deuterium-tritium accelerator neutron generator.
Background technology
In the measurement while drilling field of drilling well industry, while-drilling density logger for measuring the density on stratum in drilling process in real time, thus effectively calculates the degree of porosity on stratum, the oil storage capacity on identification of hydrocarbon layer, calculating stratum.
Current known density measuring equipment, one uses radioactive isotope power supply (such as,
137cs or
60co) launch gamma ray, then use the gamma-ray detector at two different spacing places to measure the gamma ray returned through stratum Compton scattering, calculate the density value on stratum according to the counting rate size of specific energy window.
The while-drilling density logger in chemical gamma radiation source is used to there is following shortcoming: because radioactive isotope power supply utilizes the gamma ray discharged in isotope decay process, and in order to the source strength in the precision isotope source of satisfied measurement is higher, the half-life is longer, therefore radioactive isotope power supply can produce strong radioactivity.Although adopt multiple radioactive source screening device and measure, execute-in-place environment limits the use of effective preventive means, is difficult to avoid causing health hazards to operating personnel.In addition, operating condition complicated in drilling process very easily makes radioactive sources lost, once cannot reclaim meeting severe contamination subterranean resource, even makes whole oily district scrap.In addition, due to the transmitting of the uncontrollable neutron in chemoluminescence source and gamma ray, and the secondary gamma ray that neutron produces can affect the measurement of the gamma ray that gamma ray source produces, therefore in traditional instrument, neutron porosity is measured and gamma density measurement is the different instrument of use two, and spaced apart.So just increase the length of instrument, add the cost of instrument simultaneously.
Another is known with brill density measuring instrument, is use controlled D-T accelerator neutron generator to measure density of earth formations.The energy that deuterium-tritium neutron source discharges is atomic nucleus generation inelastic scattering in the fast neutron of 14MeV and stratum and discharges gamma ray, and the decay of gamma ray is relevant to density of earth formations.But gamma detector counting rate is subject to the impact that fast neutron transports in the earth formation, therefore in order to reduce the impact of fast neutron, a gamma detector and an epithermal neutron probe is used in instrument, utilize epithermal neutron probe to transport impact on Gama Count rate to correct fast neutron, but certainty of measurement is lower.
There is following shortcoming in the instrument using deuterium-tritium neutron source to measure density of earth formations: first, although use controlled D-T accelerator neutron generator can solve the problem of radioactive source pollution, can transmit in the earth formation after but the fast neutron that the energy of its release is 14MeV is released, until just can gamma ray be discharged with the atomic nucleus generation inelastic scattering in stratum, therefore relative to chemical gamma ray source, the generation position of its gamma ray is not fixed, and the dynamic change with the change of formation influence.Thus to make gamma detector respond be not only the function of density of earth formations.From known neutron porosity log principle, although the attenuation ratio of epithermal neutron probe to neutron is more responsive, but comparatively thermal neutron is low for its counting rate that can measure, can exist with brill deuterium-tritium neutron density measurement result precision lower if use it to carry out correction to gamma detector counting.Secondly, D-T accelerator has certain working life, and be generally hundreds of hour, along with the growth of service time, the yield that its institute discharges neutron can reduce, thus causes the reduction of gamma ray count rate, and the further precision affecting density measure.
